摘要
采用萃取精馏、常压精馏以及NaA分子筛膜脱水分离技术,对四氢呋喃-己烷-水混合物中四氢呋喃的提纯进行了实验研究。结果表明,此工艺可以得到总收率在88.34%~99.47%,纯度不低于99.9%的四氢呋喃。
The purification of tetrahydrofuran from tetrahydrofuran-hexane-water mixture was studied by extractive distillation,atmospheric distillation,NaA zeolite dehydration membrane technology.The results showed that the total yield was 88.34%~99.47% and the purity was not less than 99.9% by this process.
