摘　　要：对丙酮、四氢呋喃、三乙胺、水混合物的分离进行了工艺流程设计和实验研究。针对流程做了丙酮、四氢呋喃二元溶液间歇普通精馏实验,丙酮、四氢呋喃、三乙胺、水混合物的萃取精馏实验和萃取精馏脱水实验以及丙酮、四氢呋哺混合物萃取精馏实验。结果表明,采用本工艺可得质量分数为99.7％的丙酮。The process flow was designed and experimentally studied for separation of acetone,tetrahydrofuran(THF) ,triethylamine and water mixture. Batch distillation of binary solution of acetone and THF, the extractive distillation of acetone, THF, triethylamine and water, dehydration of acetone, THF, triethylamine and water mixture by extractive distillation, extractive distillation of acetone and THF mixture were studied.Results show that purity(as mass fraction)of acetone can reach 99.7% .
