摘要
以乙烯酮和氯气为原料在溶剂中反应合成了氯乙酰氯，适宜溶剂为磷酸三乙酯，采用带夹套的填料塔式反应器。在最佳工艺条件：溶剂比（溶剂与反应生成产物的质量之比）约１－０，反应温度２０ ～３０ ℃，反应压力约９－３ ｋＰａ，原料配比ｎ（Ｃｌ２）∶ｎ（ＣＨ２ＣＯ） ＝（１－０５～１－２０）∶１ 下，氯乙酰氯收率达９２－５ ％ 以上，纯度可达９８－５％ 以上。
Chloroacetyl chloride was synthesized from ketene and chlorine as raw materials in the solvent. The adequate solvent was triethyl phosphate. The reactor was a packing tower with a jacket. Under the optimum conditions: the solvent mass ratio ( solvent to reaction product) about 1 0∶1, the material molar ratio (Cl\-2 to CH\-2CO) (1 05～1 2)∶1,reaction temperature 20～30 ℃ and reaction pressure about 9 3 kPa, the yield and the purity of chloroacethyl chloride were respectively more than 92 5% and 98 5%.
