对氯苯甲醛分子式：C7H5ClO分子量：140.57CAS号：104-88-1性质：无色片状结晶。熔点47.5℃，沸点213-214℃，72-75℃（0.399kPa），相对密度1.196（61/4℃），折光率1.5552（61℃），闪点87℃。易溶于乙醇、乙醚和苯，溶于水、丙酮。能随水蒸气挥发。制备方法：（1）由对氯甲苯氯化水解而得：将对氯甲苯和三氯化磷加入反应锅，在光照下升温至155℃，通入氯气。控制温度在160-170℃，通氯至计算量，得氯化液。搅拌下将其加入浓硫酸中，常温搅拌5h。静置分层，取下层液放入冰水中结晶，冷至5℃以下过滤。滤饼用冰水洗涤得粗品，减压蒸馏，收集108-111℃（3.33kPa）馏分即得成品。（2）对氯甲苯二氧化锰氧化法：先将对氯甲苯加入反应锅，再加入70%硫酸，在70℃以下慢慢加入二氧化锰。加毕，反应0.5h，再用水蒸气蒸馏。另外，对氯甲苯用空气氧化也可以得到对氯苯甲醛。用途：医药、染料中间体，用于制造芬那露、氨苯氨酪酸等。
