Abstract

The invention relates to nicotine salt prepared through a non-solvent method and a preparation method of the nicotine salt. The nicotine salt comprises nicotine and acid with the molar ratio of 1:(0.1-4.2). The preparation method comprises the steps that nicotine and acid are added according to the molar ratio and heated until the mixture is dissolved, stirring and a reaction are conducted for a time period, after a reaction solution is cooled to the room temperature, the solution is taken out, and the nicotine salt prepared through the non-solvent is obtained. The preparation method has the advantages of being easy to operate, efficient, environmentally friendly and the like, and the prepared nicotine salt is high in purity, environmentally friendly, efficient and capable of having few impurities.

Description

technical field [0001] The invention belongs to the technical field of novel tobacco products, and specifically relates to a green reaction method for preparing nicotine salt, which is mainly applied in the field of novel tobacco products such as e-cigarette liquid and heat-not-burn tobacco products. Background technique [0002] As a non-combustible cigarette substitute, e-cigarettes have many advantages such as non-combustion and no "second-hand smoke" hazards. It mainly uses means such as atomization to turn e-cigarette liquid containing nicotine and other components into vapor Finally, let the smoker inhale. [0003] Heat-not-burn tobacco products, unlike traditional cigarettes. Traditional cigarettes are smoked by igniting and smoking. Usually, many harmful substances will be produced at a high temperature of 350°C to 600°C. At a high temperature of 600°C to 900°C, the tobacco raw materials will be incompletely burned, and the smoke produced includes nicotine. , Tobac...
