溶剂结晶法直接制备HMX粒度分级产品

The Preparing of Size-grading products of HMX by Crystallizing in Solvent

在丙酮 -乙酸乙酯溶剂中 ,加入醋酐法生产的粗品α- HMX,根据结晶、转晶原理 ,通过控制适当的工艺条件和恰当的操作方式 ,使α- HMX全部转化为β- HMX,同时直接制备出 A、C、D、F四个不同粒度级别的产品。

The raw product α HMX obtained by means of acetic anhydride method is added to the mixture solvent of acetone and ethyl acetate. According to the principles of crystallization and transformation, and by proper control over technological conditions and operating methods, α HMX is thoroughly turned into β HMX with four different grades of A,C,D and F.
