【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。更多还原

【Abstract】 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 ∈-HNIW as 50 ℃,ultrasonic bath with frequency of 60 KHz.Results showed that the product was ∈ phase HNIW with particle size of approximately 1 μm.更多还原
