摘　　要：为实现铬系催化剂回收溶剂的充分循环利用,对回收溶剂异戊烷进行组分分析,用水对废溶剂中的异丙醇等进行萃取分离,再用填料塔对溶剂进行精馏提纯,实现铬系催化剂溶剂异戊烷的重复利用。溶剂的回收和提纯利用可有效促进铬系催化剂生产节能减排。To achieve the effective cyclic utilization of chromium-based catalyst solvent,identify the components with the analysis of the recovered isopentane solvent,using water as an extract to extract isopropyl groups from the solvent,then distillation with packed tower,isopentane solvent can be reused again.The purification of chromium-based catalyst solvent can effectively promote the production energy conservation and emission reduction.
