  • Process for preparing high energy rocket propellant plasticizer from glycerol
    Patent number: 5310433
    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.

  • Alkoxy substituted aromatic stabilizers for crosslinked CMDB propellant
    Patent number: 4299636
    Abstract: A class of alkoxy substituted aromatic stabilizers is provided for double base propellant. These stabilizers are soluble in the energetic plasticizer employed in the propellant. These stabilizers are particularly suitable and useful in diisocyanate crosslinked composite modified double base propellant because they do not react with the crosslinking agents during preparation of the propellant and impart improved thermal stability to such propellants.
