Abstract

The invention provides a batch preparation method of nicotine salt. The method comprises the following steps of 1) putting cigarette tobacco powder into a supercritical extraction device for extraction under the extraction pressure of 20-30 Mpa at the temperature of 35-55 DEG C for 1.5-4 hours; 2) carrying out first-stage molecular distillation at the heating temperature of 85-100 DEG C, carrying out second-stage molecular distillation at the heating temperature of 100-110 DEG C, and carrying out third-stage molecular distillation at the heating temperature of 130-150 DEG C; (3) weighing the third-grade fraction of the tobacco powder, and putting the third-grade fraction into a container; weighing ethyl acetate, pouring into a container, and uniformly stirring; weighing water, pouring into a container, and uniformly stirring; standing for layering, separating liquid, removing a lower-layer water phase, and reserving an upper-layer ethyl acetate phase; 4) adding benzoic acid into the ethyl acetate phase, and fully and uniformly stirring; weighing water, adding the water into the solution, and uniformly stirring; standing, layering, separating liquid, removing an upper ethyl acetate phase, and leaving a layer water phase; and the water-phase rotary evaporation dehydration being complete.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a batch preparation method of nicotine salt and its application in electronic cigarettes. Background technique [0002] Nicotine can exist in the form of aprotic state (I) (free state) and single proton state (II) or diproton state (III) (combined state, nicotine salt). The gas is transferred from the tobacco to the smoker, and the autonomic nerves and the central nervous system feel the stimulating effect. [0003] The preparation method of existing nicotine salt generally is to mix organic acid and nicotine, stir and react to obtain nicotine salt; Mass production of nicotine salts. Contents of the invention [0004] One of the objects of the present invention is to provide a batch preparation method of nicotine salt, which method comprises the following steps: [0005] Step 1) placing the cigarette powder in a supercritical extraction device for extraction, the extract...
