摘要
重点研究了C12～24正构烷烃在加热、光催化和化学催化条件下氯化反应的反应特征，并对这3种氯化方式进行了对比分析；探讨了化学催化氯代反应的影响因素，利用正交实验得出最佳工艺条件为：反应时间12h，反应温度70℃，催化剂加入量1％（质量分数），进氯速度25g／h。实验证明该催化剂可大大缩短反应时间，提高设备利用率和产品质量，为氯代烃产品的工业化生产方式的选择提供了依据。
The characteristics of chloro-substituted reaction of C12-24 n-alkanes under the condition of heating, photocatalyis and chemical catalyis are studied, and the comparative analysis on the three methods is made. The influencial factors on chloro-substituted reaction of C12-24 n-alkanes under the condition of chemical catalyst are emphatically discussed. The optimal reaction conditions are as follows： 12 hour of reaction time, 70℃ of reaction temperature, 1 wt% of the catalyst content, ：25 g/h of the feeding speed of chlorine. The research provides theoretical basis for mode selection of industrialized production of chlorinated hydrocarbons.
