1 邻氯甲苯邻氯甲苯是邻氯甲醛、邻氯苯甲酸的重要原料。工业上生产邻氯甲苯以甲苯为原料,催化氯化(或选择性氯化)后经过精馏而得,该工艺的关键技术是精馏。国内最大的氯甲苯生产厂为株洲化工厂,产能2500ｔ/ａ。国内1997年1～7月份氯甲苯的进口量为519.9ｔ。2 对氯甲苯对氯甲
1 o-chlorotoluene o-chlorotoluene o-chloroformate, o-chlorobenzoic acid is an important raw material. Orthochlorobenzene in the industrial production of toluene as raw material, catalytic chlorination (or selective chlorination) derived after distillation, the key technology is the distillation. China’s largest chlorotoluene production plant in Zhuzhou Chemical Plant, production capacity 2500t / a. China’s imports of chlorotoluene from January to July 1997 was 519.9t. 2 p-chlorotoluene chloromethyl
