摘要
A combination of thin-layer chromatography and spectrophotometry provides a reliable means for measuring typical plasticizers and stabilizers in aged double-base propellants. The use of a thin-layer chromatographic separation eliminates analysis errors encountered in other methods. Both nitrated stabilizers and nitroglycerin breakdown products are removed before measurement of the unused stabilizers and nitroglycerin. Satisfactory thin-layer separations and recoveries were demonstrated even with an application sample size of up to 40 mg. The analysis time was not significantly longer than with other methods and acceptable accuracy and precision were shown in a reliability study. © 1968.
