A gas‐liquid chromatographic procedure was developed in connection with the determination of water in nitroglycerin‐nitrocellulose pastes. The method is based on the reaction of water with 2,2‐dimethoxypropane and its conversion to acetone which is subsequently determined. The technique is simple, rapid, and shows good accuracy and precision.
A simplified method, which is less accurate but does not involve chromatography, is also proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
