Abstract
An efficient method for preparing nitrated glycerol glycol ether useful as a high energy plasticizer, by using as nitrator feed, the reaction products of an alkali metal bisulfate-catalyzed reaction of ethylene oxide and a stoichiometric excess of glycerol.
Claims8
A process for producing high energy plasticizer composition for rocket propellant comprising
- (a) contacting glycerol and ethylene oxide in the presence of a catalytic amount of dry alkali metal bisulfate;
- (b) separating out the alkali metal bisulfate;
- and
- (c) conitrating the resulting intermediate reaction products, to obtain the desired high energy plasticizer composition.
