摘要
以乙酸为原料，采用Ａｃ２Ｏ－ＰＣｌ３－Ｓ２Ｃｌ２为催化剂，进行催化氯化制备高纯度氯乙酸，产品含量≥９８．５％。同时讨论了反应温度，催化剂用量等工艺条件对氯化反应及产品质量的影响。
pure monochloroacetic acid (Purity≥98.5%)was synthesized by catalylic chlorination from acetic acid in the presence of Ac 2O-PCl 3-S 2Cl 2. The effects of various factors on the chlorination reaction and the quality of produet were discussed.
