粗苯催化氯化精制新工艺的研究

Study on New Process of Crude Benzol Refining with Catalytic Chlorination

研究了反应温度、反应时间、氯气量、催化剂用量和碱液浓度等因素对催化氯化法精制粗苯过程的影响。与硫酸法相比，在保证纯苯质量的前提下，可消除酸焦油和含酸废水对环境的污染。

The effect of the factors such as reaction temperature, reaction time chlorine quanti- ty, catalyst consumption and soda solution concentration on the crude benzol refining with catalyt- ic chlorination process is studied. Compared with sulfuric acid process, under the premise of ensur- ing pure benzene quality, the pollution of tar acid and waste water contained with acid on environ- ment can be eliminated.
