| 摘 要： | 研究了邻氰基甲苯用光氯化法制备邻氰基氯苄的中试工艺。把160 kg的邻氰基甲苯投入到300 L的搪瓷反应釜中,把3只100 W白炽灯的光照引入到邻氰基甲苯液体中,在130~155℃下以9~10 kg/h速度通入干燥的氯气,通氯约40 kg停止反应,冷却氯化液,用离心机分离析出的晶体,母液再投入到反应釜中,重复上述操作,通氯质量分别为16 kg、11 kg和6 kg,把所得的邻氰基氯苄合并,用乙醇重结晶,干燥,共得到产物168 kg,总收率81.3%,w(邻氰基氯苄)=99.2%。 |
| 关 键 词： | 邻氰基氯苄 邻氰基甲苯 光氯化 中试放大 |

| Abstract: | 160 kg o-cyanotoluene was treated at 150～155 ℃ with about 40 kg dry Cl_2 at flowrate of 9～10 kg/h under the light of white lamp of 3×100 W.Then the reactant was cooled and filtered to give o-cyanobenzyl chloride.The same operation was repeated with the mother liquor,and amounts of chlorine gas introduced were successively 16 kg,11 kg and 6 kg.The crystals were combined and recrystallized with alcohol to get 168 kg o-cyanobenzyl chloride with overall yield of 81.3% and mass fraction of 99.2%. |
| Keywords: | o-cyanobenzyl chloride o-cyanotoluene photochlorination pilot-plant-scale |
