摘要:
建立以氯化苄为原料、常压反应-减压精馏耦合高选择性生产苄叉二氯的新型工艺。基于已建立的Newton-Raphson内外层模拟方法对工艺过程进行模拟计算,考察提馏段塔板数、相邻反应器间隔塔板数、反应器台数、Cl2进料流率及其分配情况对塔底苄叉二氯纯度的影响,得出适宜的工艺条件。结果表明:在精馏塔操作压力10 kPa,反应器常压操作、温度100 ℃时,提馏段塔板数为15、相邻反应器间隔塔板数为1、反应器台数为3较为适宜; 当塔釜上升蒸汽量为10 kmol/h,Cl2分配系数为 0.34、0.33和0.33 时,塔底出料中苄叉二氯摩尔分数随着Cl2进料流率的减小而明显上升,甚至达到0.99以上。
Abstract:
The coupled atmospheric reaction-vacuum distillation technology with benzyl chloride as raw material was set up to obtain high selectivity of benzal chloride.The inside-outside method based on the Newton-Raphson method was correspondingly set up to simulate the process.Furthermore,the effects of the configuration parameters,such as the number of stripping stages,the number of separation stages between adjacent reactors and the number of reactors,and the operating parameters,such as the feed flow rate of chlorine with its distributed ratios to the reactors,on the purity of benzal chloride at the bottoms were investigated to select the suitable process parameters.Results demonstrated that,for the novel process,in which the reactor temperature was set to 100 ℃ and the column pressure was fixed at 10 kPa,the suitable choices of the number of stripping stages,the number of separation stages in the reaction zone and the number of reactors were 15,1, and 3,respectively. Besides,when the vapor boilup rate was 10 kmol/h and the distributed ratios of chlorine to the reactors were 0.34,0.33, and 0.33,with the decreasing feed flow rate of chlorine,the purity of benzal chloride at the bottoms was obviously increased and even a high purity above 0.99 was obtained.
