坎利酮的清洁生产方法
摘要：
本发明属于坎利酮生产技术领域，具体涉及坎利酮的清洁生产方法。本发明通过将氧桥水析工艺改为浓缩后溶剂提取，过滤，分离后直接进行脱氢反应；脱氢反应完成后，经浓缩提取，分离，再浓缩后，直接进行内酯反应；内酯反应完成后，减压浓缩，直接进行脱酯反应，脱酯反应完成后，减压浓缩，精制，冷却，分离，出料。本发明革除了传统工艺氧桥水析、脱氢盐析、内脂碱析-酸析、脱脂盐析及水洗过程，避免了大量有机废水的产生，达到清洁生产之目的。
摘要（英）：

The invention belongs to the technical field of canrenone production and particularly relates to a clean production method of canrenone. The method comprises the steps of changing an oxygen bridge water elutriation technology to post-concentration solvent extraction, directly performing a dehydrogenation reaction after filtration and separation, directly performing a direct lactone reaction following concentration, extraction, separation and re-concentration after the dehydrogenation reaction finishes, directly performing a degreasing reaction through pressure reduction concentration after thelactone reaction finishes, and performing pressure reduction concentration, refining, cooling, separation and discharging after the degreasing reaction finishes. The method removes oxygen bridge water elutriation, dehydrogenation, salt precipitation, lactone alkali precipitation-acid precipitation, degreasing salt precipitation and water washing of the traditional technology, avoids generation ofmuch organic wastewater and achieves the purpose of clean production.
