摘要
为了制备多种粒度的HM X,探索了用-丁内酯为溶剂重结晶HM X的原理,研究了HM X的-丁内酯溶液在不同过饱和度等条件下的结晶状况,通过控制稀释剂水的加入量和速度,以及结晶过程的搅拌强度等工艺条件,分别制备出符合G JB 2335-95标准的6种粒度类别的HM X产品。结果表明,该方法工艺简单易行,溶剂便于回收且可循环使用,低耗,无污染。
A method and principle of HMX recrystallized by γ-butyrolactone and the crystallization status of HMX in γ-butyrolactone solution under different supersaturation degree were studied. The HMx products with 6 kinds of granulation conforming with GjB2335-95 were prepared through controlling of the process conditions, such as the adding rate and the amount of water used for diluting the solvent ,and the stirring strength during the crystallizing procedure. The results indicate that the process is simple to operate, the solvent is easy to recovery and can be recycled, having the advantages of the lower consumption and no pollution.
