Determination of Phthalate Esters in Propellants

Colorimetric Determination of Diethyl, Dibutyl, and Dioctyl Phthalates in Ball Propellants

“…improved methods for the determination of phthalates in propellants (9,11,12) are still time-consuming and require a fairly large sample, which is not always available. Therefore this laboratory undertook the development of a rapid colorimetric method.…”

Reduction of Nitroglycerin by Catalytic Hydrogenolysis in Analysis of Propellants for Dioctyl Phthalate

“…The polarographic determination of phthalate is made directly from the filtered extract after catalytic hydrogenolysis. This investigation was undertaken to improve the gravimetric method for the determination of phthalates in propellants (10). In the original method, the nitroglycerin in the acetic acid extract or in the dried methylene chloride extract, acidified with dilute acetic acid, was reduced with zinc dust.…”
