INTRODUCTION

The Taliani test is essentially one in bhich a. sa•]l

of propellant 1i heated in a constant volume system,, tartJmg

with a fixed pressure of gas (usually one atmosphere) and

measuring the rate of pressure change. The original apparatus

(142) has been modified greatly by workers at the California

Institute of Technologyb) and further Improved at the Naval

Powder Factory (). In studies of the stabillsation of double

bose powder carried out at the .fllegany Ballistics Labora-

toz7 (5), the conclusion was reached that "Tallaii data obtained

under nitrogen represents a good test for gas butble formation

for ova2uation of rocket propellants, and the test conducted

=der air or oxygen gives no information other than the rate

of oxygen consumptioaw

The problem of propellant stability in general can be

divied into tWo parts: (1) the length of time the propellant

can be stored before depletion of stabilizer and subsequent

accelerated decomposition results in spontaneous ignition or

deterioration of the propellant (chemical safe-life); and (2)

the length of storas it can undergo before a significant cbane

in b&alistic properties occurs due to a breakdown of pbyaical

structure (pblyical safe-life). The term "safe-life" used

subsequently in this report refers to "chemical safe-life".

Spurlitn(6) has disussed the different types of storage failure

Ci i .LUU 1

I

in some detail, and the Naval Powder Factory has reported

investigations of tie problems of storage of JP and JFI bal-listitev(7#.

The degree of deterioration of a stored propellart can

be estimated by different methods such as chemical detari-

nation of stabilizer content (as compared to the original)

or determination of the changes in Viscosity of the nitro-

cellulose or changes In mechanical properties of the propel-

lant. Unfortunately, such data is often not easily obtained

ard is difficult to interpret in terms of residual safe-life

properties of the propellant. A good stability test that vould

give a precise measure of degree of deterloretion is dez.irabl.•

and this, together with the need for more information about

the phenomena of degradation of propallants, inspired this

irnestigation.

!XPERDMNTJAL PROMW,®uR_

In the initi-al phase of this investigation, 45-g JM•

surveillance samples which had been stored at 65.50C for

varying periods were selected to give a wide range of residual

safe-life. Subsequently, aged saqpes were prepared by placin

100-g samples of sheet N-4 (Lot PAZ. 133) in surveillance

bottles in an oven at 800C. The samples vero put in at weekly

* intervals until the first one fumed. At this point all were

2 CONni•In AL

COwNivr-AL NAVCD RPORT 30a

*reoved, providing a series of sasples of different residual

afe-life. A separate series of PAE 133 aged at 800C was

* prepared for Taliani tests at b.C and 120*C, respectively.

The twe-to-fume3 at 80C was 93 days in one case and 105 days

"in the other. This differeLce is probably due to slight

dIfferences in oven temperature. A series of sheet JPN (Lot

IXR-37) samples was prepared similarly. Other groups of

sheet N-4 (Lot PAZE 133) samples were placed in a 65.5 0 C sur-

veillance magazine and withdrawn at 40-day intervals for test-

1Mg. A series of modifib] 1 -4 (Lot hIR-47) propellantsp

differing from each other only in the stabilizer added, eas

prepared and stibJected to Taliani tests.

The Taliani test apparatus and procedure have been de-

scribed In Technical Report No. 25, pp. 34-35(4). Tts propel-

lant samples were ground in a Wiley cutting mill; portions

which passed a U. S. 18 and were held on a U. S. 50 sieve

were selected. The ground samples were weighed into Taliant

test tubes. For the tests conducted under air, the samples

were preheated in the hath for 30 sinutes, after which the

pressure was reduced to atmospheric and the initial reading

taken. The tests under oxygen and nitrogen had samples pre-

heated under air in the same manner, but, folloving the pro-

heating period, the systex was evacuated and flushed four

times with the appropriate gas before the final addition of

C0NFIDEIAL

r

gas vhich brought the internal pressure above atmospberte.

The pressure %ua than reduced to atmospberic by rM-p•.v ae

and closing a stopcock.

i jIscmssIoN

The Taliani test data are plotte4 in Furezs 1 through

17 in the Appor.i1x. Dhuplicate re~dings vero taken each half

bour and their avara~es plotted. FIgures 1 %nd 12 ahow quite

clearly that ll00C Taliani tests under nitrogen are of no

valus in detecting aging of JPN. Figures 6 an! 9 leal to the

same conclusion for N-4. Figure 2 Indicates the useftlJess

or the 1100 C test under oxygen for measuring degree of de-

terloration; Figures 1,, 7, and 10 show even momr cearly that

this test correlates wall with the condition of the powder if

the time to reach a fixed positive pressure, eog. 100 z% is

zeasured. Figures 13 and 14 show that carrying out the oxyg"

Taliani test at 120C provides a more rapid measurement viUt)t

sacrificing the good correlation of the lower temperatmv test.

Figures 3, 5, 8 and 11 abho that a Taliani teat under air

reveals deterioration only during the later stages of the

powder's safe-life.

These facts can be readily explained. On& of the gases

evolved in the Taliani test is NO. Under nitrogens this gas

durirg the test period. Unier air or oxygen, NO reacts toIo"

fOr %2, wbicb then reacts vith the paue. Thu, the imodi-

ate net result is a decrease in amount of gas present in the

"system, so long an ciffectiTe quantities of stabilizer are

present to pick L7 the 02. When the stabilizer becomes do-

plated, the ND12 attacks the nitrate asters primarily and

increases the decomposition rate of the powder.

"Allowing for the volu=e occupied by sample, there are

initially 6.7 ml of gas at n=. and 1 ata pressure in the

Tallni apparatus. This is equivalent to 2.13 x 10-4 moles.

When the gas is oxygen, 4.26 x 10- mo of NO can be oun-

verted to VD2. If the test Is carried out in an atmosphere

of air, 0.89 x 10-4 moles of IO can be oxidized. The amber

of moles of stabilizer in 1 g of a 1$ ethyl contrallto powder

* (JP2) is only 0.37 x 20"4* There are 0.93 x 10-4 moles of

stabilizer In 1 g of a 2% 2-nitrodiphenylaaine pouder (N-4).

The amount of 302 vhich each molecule of stabilizer can ab-

sorb before becoming Ineffectual has not been established.

However, It is probable thati in a Ta1ian1 test under oxyge;

centralite- or 2-nitrodipbenylaine-stabihized propellants

containing no more than 2% stabilizer are completely converted

to an unstable form through nitration of stabilizer. This

would not bold true under air vmless the powder had already

been aged substantially.

COKIlIA

MAVORD REPOSE 30a CONFIDE3IAL

The test under oxygen, in which the time required for a

fixed pressure above atmospheric to be achieved is determined,

is better able to distinguish between propellants in the

early stages of deterioration because this time is dependent

on the exact amount of effective stabilizer initially present.

It is likely that the more rapid pressure increase shown in

testing of propellants in the later stages of deterioration

under air, as compared to oxygen, is due to early depletion

of the oxygen by reaction with NO along with stabilizer de-

pletion. After this occurs, all VO produced increases the

total pressure. The increased pressure probably also acceler-

ates the decomposition catalyzed by acidic products. Under

oxygen, the NO produced must use up much more oxygen before

it can increa-e the pressure directly. In the late stages

of decoaposition, N0 2 may be liberated from the powder itself,

Figures 15 through 17 show the Taliani behavior of a

series of modified X-4 propellants. IXR-47A contains the

customary 2% 2-nitrodipbenylamine. In IXR-47B, this stabi-

lizer is replaced by the same percentage of carbazole; in

IXR-47C, by diphenylamine; in IXR-47D, by etI1l centralite;

and in IXR-47E, by a mixture of 1% 2-nitrodiphenylamine vith

1% ethyl centralite. IXR-47F contains no stabilizer. To

insure that no differences would occur in composition other

than stabilizer, a single 150-1b batch of unstabilized N-4

was prepared and then dividade into six parts. The appropldah

stabilizer was then added by dry mixing.

As the graphs show, the test under nitrogen indicates the

unstabilized propellant to be the most stable one and the

propellant stabilized with the 1:1 mixture of 2-antrodipbeql-

-sine and centralite to be the least stable. This is, of

course, contrary to all that fs known about the relative safe-

life of s'.abilized and unstabilized propellants. The test

under oxygen gives results which fit the facts of safe-life

mnch better. Here the unstabilized prcpellant reaches 100 m

pressure in under 6 hours. At 13. hours, the dipbenylazNe-

stAbilized propellant is the next to fall. Dipbeiglamine is

notorious as a poor stabilizer fw double-base propellants

because of its alkalinity. The other four propellants all

reach 100 mm pressure at about the same time, approximately

20 hours, the one stabilized with the centralite - 2-nitro-

dikenylamine mixture lasting slightly longer than the others.

Centralite and 2-nitrodipherglamine, which are in three of

these latter four propellants, are known to be good stabilizers

for double-base propellants. According to Davis(8), carbazols

Is an excellent stabilizer at 110C (the temperature of this

test), but an extresely poor one at 600 and 75*C.* Naturally,

*The stabilizing power of carbazole and the other stabilaersin the modified N-4 compositions is wo; under inveet41-tionby measuring time-to-fues at various t.peratures.

i.M high temperature test is subject to errors involved in

extrapolation of data and conclusions to lower temperatures

at which differest reactIons may predominate.

Figures '8 througl% 21 illustrate how oxygen Taliani data

can be used in the determination of residual safe-life of a

propella.,t which has been in storage. The relationships

bet'.een data obtained from the Taliani tests (the time required

to achieve a pressure of +100 mm) and the percent of safe-

life remaining have been plotted. The latter value has been

computed from the ratio between length of storage at 800 C

ard time required for the sa-ple to evolve NO2 fwZ3 at that

temperature. Of cour;, estiMates Of t A f.Oe-WiSe time of

a new propellant foraulation are best obctained by extrapolation

of temporature-decomuposition rate data to lower temperatures.

In each case, the plot of the logarithm of the time required

to reach 100 mm pressure vs percent or -afe-life remaining

approximates a straight line, and the least squares line is

shown in each of the figures.

Some speculation on the theoretical interpretation of this

data is in order here. It can reasonably be assu=ed that, for

any propellant forwulation, the time required to reach 100 =

pressure Is equal to some constant value plus a factor pro-

portional to the concentration of "active" stabilizer.

If the plot of log (tp-c) versus t yielded a straight line,

It should be pointed out that the inogeneity of the

propellant colloid restricts the precision with vhich quanti-

tative measurements of the rate of loss of safe-life can be

made. Consequently, a proper evaluation of c from Taliani

data on propellants being decomposed in constant temerature

storage would require many oxygen Tallani tests on may pro-

pellant lots of identical formulations so that statistical

treatment could smooth out individual Irrekularities. The

precision of the oxygen Taliani test as a measure of the

residual aafe-life of propellants could alco be increased

by thus obtaining additional data. The lower temperature

Taliani tests permit greater precision than the high temper-

ature ones by lessening the effect of slight variations iL

preheat time which are due to the manipulations Involved in

flushing the system.

COI nIDUT NUMORDEPORT

The utility of the oxygen Tallani test for measuring

the degree of propellant deterioration during storage has

been demonstrated above, and the possible utility of such a

test for evaluating proposed stabilizers has been Indicated.

The use of the test in specifications or as a control for the

manufacture of propellants should be considered. The dis-

crepancy between test time for the N-4 sheet lot PAE 133# a

regular Picatinny Arsenal production lot, and the X-4 lot

IXR-471, prepared by dry addit5.on of stabilizer to the un-

stabilized sheet, ay be due to the differences in processbW

or to possible differences in coaposition. With suitable

adjustment of sample size ur of voluse of the apparatus, the

, test can be applied to any solventless propellant based on

nitrate esters by providing sufficient oxygen for ccoplete

depletion of stabilizer. Of course if gases otber than NO

are evolved reptily, azW fixed positive pressure = be achieved

prior to exhaustion of stabilizer.

The nitrogen Taliani test is useful for quickly ccmparing

rates of gas evolution frcm different propellants, but its

validity as an absolut, measure of the tendency of propellants

to fissure is open to question. The permeability of dilferent

propellant compositions may be expe-Ced to vary as weio as

their gas evolution rates. Ernsberger and Olsen(9) have

conJuded, on the basis of thei r experimental work on evolution-

and diffusion of gases in ballistite, that the pressure built

up in a solid 2-inch-diameter cylinderof JPN after xtorage In

air for an extended peritd at 600C may be 3-.uffic-ent to

cause cracking.

An investigation of the effect on the oxy-.n Tallani test

of incorporation of vary•ind quantities of stat=%zer into the

nitrocellulose-nitroglycerin system is. conte.plated. This

would provide further information about the r-lidity of the

assi~ption relating test time to "active" stabl zer content.

The effect of varying the nitrocellulore-nitrzElycerin ratio

is also to be investigated.

A Taliani test under oxygen has been fc~nd to give a

quantitative measure of the residual safe-life of propellants

in storage. A relationship betieen the azorz:.t of "actlvc"

stabilizer and the test re3ult has been propozed. The oxygen

Tallani test is also useful for evaluating propeared new stabi-

lizers.
