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-propyl-ene glycol dinitrate were investigated. Results show that H-ZSM-5 catalyst has good catalytic properties. Under the optimum reac-tion conditions of H-ZSM-5 as catalyst,dichloromethane as solvent,the reaction temperature 15 ℃,reaction time 6 hours and N2O5/ECH molar ratio 1.11.0 ,the conversion of ECH is 100%. The selectivity and yield of 3-chloro-1,2-propylene glycol dinitrate are 98 . 0%.
