Abstract

本发明是从烟叶中提取烟碱的新工艺。是以甲基叔丁基醚和甲醇为提取溶剂，在50～70℃温度和常压下，提取烟碱的新工艺。该工艺具有收率高，三废少、工艺路线短等特点。

Description

烟叶提取烟碱新工艺
烟碱是天然烟草中含有的主要生物碱，它的用途十分广泛，如用于粮食、蔬菜、油料水果等人类食用的农作物的无残毒，无公害的高效生物型杀虫剂：在医药工业上，用于心血管、皮肤病、蛇毒咬伤等病的特种药的原料，在烟草工业上用于高级香烟的品质改良剂。
近年来，国内外采用多种不同的工艺路线提取烟碱，本发明涉及的新工艺是针对老工艺所采用的酸、碱水溶液提取、中和、水蒸汽蒸馏、溶剂萃取老工艺路线的缺点如收率低、三废多、工艺路线长而开发成功的、本发明的新工艺路线短、收率高、三废少。其最佳工艺条件为：混合溶剂中甲基叔丁基醚含量50％，甲醇含量50％提取温度55℃～65℃，压力为常压。
