Abstract:

An improved nitrocellulose recovery process is being used that involves extraction of the solvent-extractable materials nitroglycerin, dinitrotoluene, phthalates, stabilizers, etc. from scrap nitrocellulose-base propellants with methylene chloride, leaving essentially nitrocellulose. After the extraction, most of the methylene chloride is eliminated from the nitrocellulose by a special technique and the nitrocellulose while still moist is incorporated with other ingredients in the manufacture of new propellant. In connection with this process, it was necessary to develop a method for determining methylene chloride in the moist residue. It was found that this could be done by gas chromatography after extracting the methylene chloride with benzene.
