一种从17α‑羟基黄体酮生产废液中回收甲苯和二乙氧基甲烷的方法
摘要：
本发明提供了一种从17α‑羟基黄体酮生产废液中回收甲苯和二乙氧基甲烷的方法，所述17α‑羟基黄体酮生产废液中含有甲苯、二乙氧基甲烷、乙烯基异丁基醚、异丁醇和乙醛，所述方法包括以下步骤：废液蒸馏、甲苯‑水共沸蒸馏、甲苯‑水冷凝、甲苯‑水液液分离、有机相蒸馏、冷凝83～88℃组分、乙烯基异丁基醚聚合反应、混合液相中和反应、二乙氧基甲烷蒸馏、二乙氧基甲烷冷凝、冷凝低于83℃组分。本发明实施例充分利用废液中各物质沸点的差别，将17α‑羟基黄体酮生产废液分成三段，合理分段有利于废液的进一步处理和有效成分的高效回收，具有工艺合理、方法简单、环保节能、操作成本低、产品回收率高等优点。
摘要（英）：

The invention provides a method for recycling methylbenzene and methylene diethyl ether from 17alpha-hydroxyl progesterone production waste liquid. The 17alpha-hydroxyl progesterone production waste liquid contains the methylbenzene, the methylene diethyl ether, vinyl isobutyl ether, isobutyl alcohol and acetaldehyde. The method comprises the following steps: distilling the waste liquid; performing azeotropic distillation on the methylbenzene and water; condensing the methylbenzene and the water; performing liquid-liquid separation on the methylbenzene and the water; distilling an organic phase; condensing a component of 83 to 88 DEG C; carrying out a polymerization reaction on the vinyl isobutyl ether; carrying out a neutralization reaction on a mixed liquid phase; distilling the methylene diethyl ether; condensing the methylene diethyl ether; condensing a component below 83 DEG C. In the embodiment of the invention, the 17alpha-hydroxyl progesterone production waste liquid is partitioned into three segments by fully utilizing the difference among boiling points of substances in the waste liquid, so that reasonable segmenting has contribution to further treatment of the waste liquid and efficient recycling of effective components; the method has the advantages of reasonable process, simple method, environmental friendliness, energy saving, low operation cost, high product recycling rate and the like.
