摘要

目的:优选从八角枝叶提油废水中提取莽草酸的工艺。方法:以莽草酸含量为指标

通过正交试验优选石灰膏和活性炭脱除废水中杂质的工艺条件

将除杂后废水通过201×7（717）型树脂柱进行阴离子交换

用1%HCl洗脱

收集洗脱液

浓缩得粗品;粗品用冰乙酸重结晶

得莽草酸产品。结果:石灰膏除杂最佳工艺为石灰膏用量5%

混合后60℃保温20min;活性炭除杂最佳工艺为用量5%

混合后50℃保温60 min

可在任意pH下操作。莽草酸平均得率37.60%

产品中莽草酸纯度98.84%。结论:该工艺简单易行

可有效处理八角枝叶提取挥发油后的废水

且适于工业化大生产。

Abstract

Objective:To optimize extraction technology of shikimic acid from wastewater

which was produced after volatile oil was extracted from leaves and stems of Star Anise.Method:With the content of shikimic acid as index

orthogonal tests were adopted to optimize technology conditions for removing impurities and pigments by lime paste and powdered activated carbon

then wastewater was enriched by resin 201×7（717） anion exchange resin column

eluted by 1%HCl

collected eluate

concentrated to receive crude products;The crude products was recrystallized by acetic acid

obtained shikimic acid products.Result:Optimum impurity removal process of lime paste was as following:added 5% lime paste as per the westewater volum

incubated for 20 min at 60 ℃ after mixing;Optimum impurity removal process of activated carbon was:added 5% as per the westewater volum incubated for 60 min at 50 ℃ after mixing

operation at any pH.The average yield and purity of shikimic acid were 37.60%

98.84%

respectively.Conclusion:This optimized technology was simple and feasible by deal with wastewater effectively

and it was suitable for industrial production.
