\u003C\u002Fp>\u003Cp>（1）乙酸氯化法是在碘、磷、硫或磷和硫的卤化物等催化剂存在下，用氯气将乙酸直接氯化而得。除生成氯乙酸外，还有深度氯化的副产物如二氯乙酸、三氯乙酸。此法原料消耗较低，工艺简单，氯乙酸产率可达92%。\u003C\u002Fp>\u003Cp>\u003C\u002Fp>\u003Cp>（2）三氯乙烯水合法是以93%的硫酸为催化剂，反应温度约160-180℃。此法可得高纯度的氯乙酸，产率可达90%，但副产盐酸较多。\u003C\u002Fp>\u003Cp>\u003C\u002Fp>\u003Cp>（3）氯乙醇氧化法是在60℃用60%的硝酸氧化，氯乙酸收率超过90%。在北美洲以乙酸氯化法为主，西欧以三氯乙烯水合法为主。我国采用乙酸氯化法生产：将定量的冰醋酸加入反应锅，以冰醋酸重量的3.5%硫黄粉作催化剂，预热至90℃以上，开始通入适量的氯气，两只反应锅串联通氯，主锅控制温度为98±2℃，副锅为85-90℃，通氯速度约70kg\u002Fh，待反应锅内物料的相对密度为1.350（80℃）时，即反应到达终点。将反应物抽至酸罐，冷却结晶，液相为少量乙酸、二氯乙酸、氯化硫和少量氯乙酸，分离出结晶体，再在38℃以下把母液抽尽即为成品。每吨产品约产生150公斤母液，可进一步氯化制成二氯乙酸、二氯乙酸甲酯及氯仿。三氯乙烯水合法同时进行水的加成和水解：反应温度160-180℃，反应中硫酸浓度应保持在93%，控制三氯乙烯和水的比例。硫酸消耗不超过50kg，副产30%的盐酸2.57t。工业品氯乙酸为无色或略带淡黄色结晶体。原料消耗定额：冰醋酸（98%）730kg\u002Ft、氯气860kg\u002Ft、硫磺26kg\u002Ft。\u003C\u002Fp>\u003Cp>\u003C\u002Fp>\u003Cp>精制方法：用氯仿、四氯化碳、苯或水重结晶后，放入真空干燥器中用五氧化二磷或浓硫酸干燥。若需进一步纯化可在硫酸镁存在下蒸馏。馏出物熔化后分步结晶，产品在真空或干燥氮气中贮存。\u003C\u002Fp>\u003Cp>（4）在乙酸酐存在下往乙酸中通入氯气即可制取氯乙酸：\u003C\u002Fp>\u003Cp>\u003C\u002Fp>\u003Cp>经蒸馏精制即得氯乙酸成品。\u003Cbr \u002F>（5）取工业氯乙酸于35～40℃下放置约半个月，渗析出结晶中的液态乙酸和二氯乙酸，然后溶于苯中，蒸出部分苯，停止加热后冷却重结晶，过滤结晶，以去除三氯乙酸，用苯和少量乙醚洗涤，即得无水纯氯乙酸。\u003C\u002Fp>\u003Cp>2.制法： \u003C\u002Fp>\u003Cp>于装有搅拌器、温度计、回流冷凝器（连一道气管至氯化氢气体吸收装置）、通气导管（伸入瓶底）的反应瓶（预先称重）中，加入冰醋酸（2）150g（2.5mol），红磷6g，加热至100℃，慢慢通入氯气，保持反应℃在105～110℃之间。直至质量增加约85g，大约需要5h。蒸馏，先收集沸点较低的乙酰氯和未反应的乙酸，再收集150～200℃的馏分。此馏分的液体冷却后固化。尽可能的倾去未固化的液体，将固体物重新蒸馏，收集182～192℃的馏分，冷却后固化mp63℃，得氯乙酸（1）150～175g，收率64%～74%。\u003C\u002Fp>","\u003Ctd>\n\n\u003Ctable>\n\u003Ctbody>\n\u003Ctr>\n\u003Ctd>\u003Cstrong>
