D，L-萘普生合成原料新戊二醇回收工艺的研究

摘要

Synthesis of D,L-naproxen via ketalization,neopentyl glycol consume a large amount of raw materials,through rearrangement,hydrolysis to produce a large number of containing 2,2-dimethyl-3-bromopropanol high COD waste water.Studied the wastewater via epoxidation,hydrolysis of recycle neopentyl glycol process,thereby lowering the production cost,developing circular economy power environmental protection.%在合成D，L-萘普生缩酮过程中，消耗大量原料新戊二醇，经重排、水解后产生大量含有2，2—二甲基—3—溴丙醇的高COD废水。研究了该废水经环氧化、水解回收新戊二醇的工艺，进而降低生产成本，发展循环经济助力环境保护。
