麻黄碱生产工艺改进分析

Discussion about Reformation of Ephedrine Production Technology.

目前没有经济、成熟的方法处理麻黄碱生产工艺废水。改革现有工艺苛化前工序对麻黄草预处理 ,采用先进的分离手段处理浸取液 ,可以使麻黄碱浸取条件温和 ,浸取液中污染物减少 ,苛化时碱耗减少 ,并有可能使酸水用于浸取。

There are no economic and ripe methods treating ephedrine production wastewater now.The reformation of present processes that precede causticizing,these are the pretreatment of ephedra grass and the treatment of its leaching solution by advanced separation methods,may make the leaching condition of ephedrine mild,pollutants in the leaching solution and consumption of caustic sodium in causticizing decreased and acid water used in leaching.
