本发明属于有机合成技术领域，具体涉及种氯乙基正丙醚的合成工艺。本发明采用高效催化剂，以2-正丙氧基乙醇和氯化亚砜为主要原料，通过滴加氯化亚砜，严格控制反应速率，后经升温、保温得到粗品，再经精馏提纯得到氯乙基正丙醚，产品外观清澈透明，纯度达99.22％以上，收率大于98.53％，水含量小于0.19％。与传统工艺相比，本发明无废水产生，精馏产生的前馏和釜底料及催化剂能够进行循环利用，纯度和收率高，水含量低，适合工业化生产。 The invention belongs to the technical field of organic syntheses, and specifically relates to a compounding technology of chloroethyl n-propyl ether. The compounding technology comprises the steps of adopting an efficient catalyst taking 2-n-propoxyl ethyl alcohol and thionyl chloride as main raw materials; strictly controlling the reaction speed by dripping the thionyl chloride; obtaining a crude product through temperature rising and temperature preservation; obtaining the chloroethyl n-propyl ether through rectification and purification. The product appearance is clear and transparent, the purity is more than 99.22 percent, the yield is greater than 98.53 percent, and the water content is smaller than 0.19 percent; compared with the prior art, no wastewater is generated, fore-distillate and a kett
