摘要
研究了萃取精馏技术和反应萃取精馏技术在回收四氢呋喃(THF)中的应用。选择了萃取剂和反应萃取剂,设计了工艺流程,优化了操作条件。试验结果表明,采用以上技术从制药废液中回收的THF,纯度(按质量分数计)可达到99.4%
The application of extractive distillation and reactive extrative distillation in the reco very of tetrahydrofuran (THF) has been studied. The extractants and reactive extractants were selected, the process flow and optimum operation conditions were determined in the study. The results show that the purity (as mass fraction) of THF recovered from waste pharmaceutical liquor can reach 99.4%.
