摘　　要：该文以有机碱作为缚酸剂,研究了4-氯-4,5-二甲基-1,3-二氧杂环戊烷-2-酮(CDMDO)脱氯化氢制备4,5-二甲基-1,3-二氧杂环戊烯-2-酮(DMDO)的工艺。优化的工艺条件为:N,N-二甲基苯胺作为缚酸剂,甲苯为溶剂,反应温度110℃,CDMDO转化率70%。The organic bases as binding agent of HCl were investigated in synthesis of 4,5-dimethyl-1, 3-dioxolen-2-one （ DMDO ） from 4-chloro-4, 5-dimethyl-1, 3-dioxolan-2-one （ CDMDO ）. Optimized reaction conditions of this technology were that N, N-dimethylaniline are used as binding agent, toluene as solvent, reaction temperature is 110 ℃. Under optimized conditions, the yield was 70%.
