摘　　要：直接法合成的苯基氯硅烷粗单体是一种成分复杂的多组分混合物,其分离纯化较为困难,国内外鲜有报道。文中设计了4种分离方案并与文献中已有的分离方法进行对比。利用Aspen Plus对以上5种分离方案进行严格模拟计算,旨在保证一苯基三氯硅烷、二苯基二氯硅烷的纯度及收率的前提下找出年度费用最低的分离方案。基于易分离度系数法的分离方案年度总费用最低,比现有分离方案的年度总费用降低了7.8%。以该流程为初始方案,利用调优法找出4组相邻分离方案。通过对4组分离方案进行精确模拟计算,得到结论:调优方案3年度总费用最低,为苯基氯硅烷单体分离的最优分离方案,比初始方案年度总费用低了3.5%。It is very difficult to separate the crude phenyl chlorosilane mixture synthesized by the direct method and the separation schemes are rarely reported in the published literature. 4 separation schemes were provided and compared with the scheme mentioned in the published literature. The strict simulation was performed for the above5 separation schemes by Aspen Plus to find out the scheme with the minimum total annual cost（ TAC） under the precondition of purity and yield of phenyl trichlorosilane,diphenyl dichlorosilane. The TAC of the scheme based on Easy Separation Coefficient Method（ ESCM） is minimum,which is 7. 8% lower than that of the reported scheme in literature. Based on the initial ESCM scheme,another 4 similar separation schemes were developed by evolutionary method. A comparative study of the 4 schemes shows that the scheme 3 is the optimal scheme with a minimum TAC,which is 3. 5% lower than that of the initial ESCM scheme.
