摘　　要：采用常压脱己烷、减压脱轻、减压脱重组分三步精馏法有效地从乙叉降冰片烯(ENB)残液中回收ENB产品,和目前ENB回收工艺相比,解决了ENB回收过程中产生大量废水且回收产品纯度低的问题,回收后ENB的质量分数达到99.5%以上,且整个回收过程中未产生废水,达到了清洁生产的目的,具有非常好的应用前景。ENB products were recovered from（ENB）residue by 3steps rectification methed,namely atmospheric hexane removal,removal of light components by pressure reduction,removal of recombinant fraction by pressure reduction.Compared with the current ENB recovery process,this technology can solve the problems of a large amount of waste water produced in the process of ENB recovery and the less purity of the product.The quality fraction of ENB after recovery is up to 99.5%,The waste water is not produced in the whole recovery process,and the utility model achieves the goal of cleaner production,and has a very good application prospect.
