【摘要】 以环氧乙烷和工业盐酸为原料，用无水氯化钙磷酸氢二钠作催化剂，合成了氯乙醇。采用环氧乙烷底吹法，去掉了搅拌和二次回流装置，降低了环氧乙烷的消耗，节约了设备投资，增加了生产安全性。投入工业生产后，产品质量分数稳定在５０ ％ 左右，环氧乙烷耗量比理论值仅多７％ ～８％ 。更多还原

【Abstract】 In this paper,chloroethanol is synthesized by the reaction between ethylene oxide and industrial hydrochloride with CaCl 2/Na 2HPO 4 as catalyst.The bottom-blowing method of ethylene oxide is used without stirring and secondary refluxing.By this method,the investment of equipment and the amount of ethylene oxide are reduced,and the safety in the process is increased.The content of chloroethanol is controlled stably at about 50%. The amount of ethylene oxide is only 7%～8% higher than theorical value.更多还原
