Problems solved by technology

Nicotine salt is used as a substitute for nicotine in the second-generation e-liquid products, and the smoking stimulation is significantly lower than that of the first-generation e-liquid, but the disadvantage is that it usually needs to provide a higher concentration of nicotine salt (equivalent to nicotine content> mL) in order to make smokers feel satisfied when using e-cigarettes

Embodiment 1

[0029] This embodiment provides an electronic cigarette liquid, which is prepared from the following raw materials: 1 part by weight of nicotine, 2 parts by weight of niacin, and 50 parts by weight of an organic solvent. The organic solvent is composed of propylene glycol and glycerin in a volume ratio of 7:3 .

[0030] The specific steps of the preparation method of the e-cigarette liquid are: sequentially adding nicotinic acid and an organic solvent to the nicotine, heating to 50° C., and stirring while heating to fully react for 10 hours to obtain the e-cigarette liquid with a pH of 6.8.

Embodiment 2

[0032] This embodiment provides an electronic cigarette liquid, which is prepared from the following raw materials: 5 parts by weight of nicotine, 10 parts by weight of p-fluorobenzoic acid, 300 parts by weight of organic solvent, and 10 parts by weight of mint flavor. Triols are composed in a volume ratio of 7:3.

[0033] The preparation method of the electronic cigarette liquid comprises the following steps: sequentially add p-fluorobenzoic acid and 30% organic solvent to nicotine, heat to 80°C, stir while heating to fully react for 1 hour, and then add mint after cooling down to room temperature flavor essence, and then add the remaining organic solvent, and continue to stir for 4 hours to obtain the e-cigarette liquid with a pH of 8.0.

Embodiment 3

[0035] This embodiment provides an electronic cigarette liquid, which is prepared from the following raw materials: 2 parts by weight of nicotine, 3 parts by weight of p-aminobenzoic acid, 95 parts by weight of organic solvent, and 5 parts by weight of mixed fruit flavor essence. The organic solvent is composed of propylene glycol and Glycerol is composed at a volume ratio of 3:7.

[0036] The preparation method of the e-cigarette liquid, the specific steps are: add p-aminobenzoic acid and 30% organic solvent to nicotine in sequence, heat to 60°C, stir while heating to fully react for 5 hours, after cooling down to room temperature, add the mixed fruit flavor, then add the remaining organic solvent, and continue to stir for 4 hours to obtain the e-cigarette liquid with a pH of 7.2.

Abstract

The invention relates to an electronic cigarette liquid, a preparation method thereof and a novel acid for preparing a nicotine salt and an electronic cigarette. The electronic cigarette is prepared from the following raw materials in parts by weight: 1 to 5 parts of nicotine, 2 to 10 parts of organic acid and 50 to 300 parts of organic solvent, wherein the organic acid is any one or a mixture ofnicotinic acid, parafluorobenzoic acid and para aminobenzoic acid. The electronic cigarette is prepared through reaction of the nicotine and a specific type of organic acid in the organic solvent. Compared with other existing electronic cigarette liquids, the electronic cigarette liquid disclosed by the invention has the advantages of lower nicotine salt concentration (the content of the nicotineis lower than or equal to 20mg / mL), better smoking feel, unique atomizing effect and smoking feel, and certain health care function.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to an electronic cigarette liquid, a preparation method thereof, and a novel acid for preparing nicotine salt and electronic cigarettes. Background technique [0002] E-cigarette liquid is a liquid used in electronic cigarettes to produce atomization effects. E-cigarette liquids on the market are generally composed of propylene glycol, glycerin, flavors and fragrances, and nicotine. The first generation of nicotine used in e-liquids on the market is its free base. The disadvantage is that the satisfaction of smoking is low, and the stimulation of nicotine concentration is too strong to be used. Nicotine in the form of nicotine salt is generally used in pharmaceutical intermediates and pharmaceutical fields. The reason is that compared with the form of nicotine free base, the form of nicotine salt has the advantages of convenient use, high purity and few imp...
