摘要
本文研究了使用两性离子交换树脂柱直接从发酵液中吸附 ,然后以热水为脱附剂分离L 苹果酸的工艺技术和最佳操作条件。与老工艺相比较 ,生产收率提高 10 %以上 ,生产成本降低 10 %以上 ,几乎可完全消除生产中的三废污染 ,是一种对环境有利的清洁生产工艺。
A new malic acid separation technology was studied. At first, malic acid was adsorbed from fermation liquid with amphoteric ion-exchange resin.Then hot water was used as desorbtion to desorb it from resin.With this method,production rate can be improved by 10% and production cost can be reduced over 10%.Also it almost diminishes the pollutions.It is a kind of pollution-free production technology.
