| titleOfInvention | Direct production of beta hmx |
| abstract | 1. THE PROCESS FOR THE DIRECT PRODUCTION OF BETA-HMX WHICH COMPRISES SUBSTANTIALLY CONTINUOUSLY FEEDING INTO A PRECHARGED NITRATOR ZONE RAW MATERIALS COMPRISING HEXAMINE, NITRIC ACID, AMMONIUM NITRATE AND ACETIC ANHYDRIDE, THE HEXAMINE BEING DISSOLVED IN ACETIC ACID AND THE RATE OF FEED OF SAID HEXAMINEACETIC ACID SOLUTION BEING SUBSTANTIALLY GREATER THAN THE RATE OF FEED OF THE ACETIC ANHYDRIDE IN SAID NITRATOR ZONE, VIGOROUSLY AGITATING TOGETHER THE AFORMENTIONED MATERIALS AND MAINTAINING THEM UNDER A TEMPERATURE BETWEEN 40-50*C. FOR AT LEAST 15 MINUTES UNTIL AT LEAST SOME NITRATION HAS OCCURRED, WITHDRAWING REACTION PRODUCT FROM THE NITRATOR ZONE TO A FURTHER ZONE WHEREIN THE WITHDRAWN REACTION PRODUCTS ARE FURTHER AGITATED AND PERMITTED TO AGE AT A TEMPERATURE BETWEEN 40-50*C., WITHDRAWING AT LEAST A PORTION OF THESE AGED MATERIALS TO A SECOND NITRATOR ZONE WHEREIN FURTHER QUANTITIES OF NITRIC ACID, ACETIC ANHYDRIDE AND AMMONIUM NITRATE ARE INCORPORATED INTO THE REACTION, SUBJECTING THE MATERIALS IN THIS SECOND NITRATOR ZONE TO VIGOROUS AGITATION AND MAINTAINING THE TEMPERATURE BETWEEN 40-50*C., WITHDRAWING SUCH REACTION MIXTURE FROM THE SECOND NITRATOR ZONE TO A FURTHER ZONE WHEREIN THE WITHDRAWN REACTION PRODUCTS ARE FURTHER AGITATED AND PERMITTED TO AGE AT A TEMPERATURE BETWEEN 40-50*C. WHEREBY A REACTION MIXTURE CONTAINING A SUBSTANTIAL PORTION OF BETA-HMX IS PRODUCED, WITHDRAWING SUCH REACTION MIXTURE TO FURTHER TREATMENT WHICH INCLUDES HYDROLYSIS, FILTERING, WASHING AND DRYING FOR OBTAINING A CRYSTALLINE BETA-HMX PRODUCT. |
