本文介绍了以废次烟叶为原料 ,采用新型萃取剂 GTM— 2 0 ,提取生产硫酸烟碱的新方法。研究结果表明 ,GTM— 2 0萃取剂具有萃取速率快 ,萃取温度低 ,萃取率高 ,使用过的萃取剂不需处理便可反复使用 ,因而萃取剂损耗小。本方法生产工艺简单 ,生产成本较低 ,是生产硫酸烟碱的有效方法。
This paper introduces a new method of extracting nicotine sulphate using waste tobacco as raw material and using a new extraction agent GTM-20. The results show that GTM-20extractant has the advantages of fast extraction rate, low extraction temperature and high extraction rate. The used extractant can be reused without being treated, so the loss of extractant is small. The method has simple production process and low production cost, and is an effective method for producing nicotine sulfate.
