摘　　要：采用溶剂-非溶剂重结晶法研究了六硝基六氮杂异伍兹烷(HNIW)的超细化制备工艺。通过改变溶剂与非溶剂的体积比、溶液温度、进料速度、超声波振荡频率等影响因素,研究了超细∈-HNIW的粒度及粒度分布,确定的最佳工艺条件为:溶剂为乙酸乙酯,非溶剂为石油醚,溶剂与非溶剂的体积比为1∶5,50℃下的∈-HNIW饱和溶液体系,超声波振动频率为60kHz,所得ε-HNIW的粒度约1μm。Solvent non-solvent recrystallization to prepare ultrafine HNIW was studied. The particle size and particle size distribution of ultra fine HNIW were resarched by changing of factors such as the volume ratio of solvent and non-solvent, solution temperature, feeding rate and ultrasonic frequency. The optimally conditions were determined with acetic ether as solvent and petroleum ether as non-solvent,and the volume ratio of solvent and non solvent was 1 ： 5 and the temperature of the saturated solution of ε-HNIW as 50 ℃, ultrasonic bath with frequency of 60KHz. Results showed that the product was ; phase HNIW with particle size of approximately 1μm.
