提高太安堆积密度的结晶工艺研究

Process Research on Crystalline to Improve PETN Bulk Density

以季戊四醇经浓硝酸酯化后的粗制太安为原料 ,在溶剂下重结晶得精制成品太安。讨论了不同溶剂、结晶速度、结晶溶液 p H值对太安堆积密度的影响。关键词 :太安 ;堆积密度 ;

Refinery PETN through re crystallization in solvent by using fatted crude PETN by concentrated nitric acid as raw material was produced. The PETN bulk density affected by different solvents, crystallization speed & solution pH value was discussed.
