摘要
研究了环氧氯丙烷(ECH)与N2O5的绿色硝化反应过程。考察了催化剂种类、反应温度、反应时间、溶剂对制备3-氯-1,2-丙二醇二硝酸酯的硝化过程的影响。结果表明,酸性分子筛催化剂H-ZSM-5具有较好的催化性能,以其为催化剂,CH2Cl2为溶剂,反应温度15℃,反应时间6 h,N2O5与ECH摩尔比1.1:1.0的优化条件下,ECH的转化率达100%,3-氯-1,2-丙二醇二硝酸酯的选择性和收率达98.0%。
The green nitrating reaction process of epichlorohydrin （ ECH ） with dinitrogen pentoxide （ N2O5） was studied. The effects of catalyst type, reaction temperature, reaction time and solvent on the nitrating process of preparing 3-chloro-1 ,2-propylene glycol dinitrate were investigated. Results show that H-ZSM-5 catalyst has good catalytic properties. Under the optimum reaction conditions of H-ZSM-5 as catalyst, dichloromethane as solvent, the reaction temperature 15℃, reaction time 6 hours and N2O5/EcH molar ratio 1.1 ： 1.0 , the conversion of ECH is 100%. The selectivity and yield of 3-chloro-l,2-propylene glycol dinitrate are 98.0%.
