【Abstract】 Butadiene is reacted、with chlorine to form3,4-dichlorobutylene and 1,4-dichlorobuty-lene、where the latter can be converted to the formerbvdistillation-isomerization reaction. According to the basic prineiple of process development a two～tower system is developed. The diStillation-isomerization process can be divided into distillation process and isomerization reaction process.A simple reaction kinetics model and a distillation design model have been established.The ontimization of technological conditions and sensitivity analysis have been studied.Based on the optimization results the authors propose to adopt liquid back feed,lower、and high liquid recycle. The modeling result has been confirmed by pilot plant tests.更多还原
