ABSTRACT:
HMX is obtained in substantially increased amount by means of a novel modcation of the conventional process for producing HMX by reaction of hexamine with a nitrating agent consisting of HNO.sub.3 --NH.sub.4 NO.sub.3 solution in acetic acid-acetic anhydride medium, wherein the nitrating agent, hexamine solution and acetic anhydride are concurrently added to a mixture of acetic acid and acetic anhydride called a "heel". The modification involves incorporating a small amount of hexamine in the heel prior to the addition of a major portion of the nitrating agent.
