Embodiment 1

[0056] Embodiment 1: the synthesis of tetraacetylglucose phenethyl alcohol

[0057]Add 5g pentaacetylglucose and 3g phenethyl alcohol in the three-necked flask, add 50ml methylene chloride therein, stir to make it fully dissolved in the methylene chloride, then put the three-necked flask into an ice-water bath, continue to stir for 10 minutes, and Under the condition of a water bath, a certain amount of catalyst is slowly added dropwise therein, the catalyst is equivalent to 100-400% of the mole fraction of pentaacetylglucose. After the addition of the catalyst is completed, the ice-water bath is removed, and the reaction is continued to stir at room temperature for 3 hours. After the reaction was complete, the mixture was filtered and the solvent was removed by rotary evaporation. The residue was dissolved in 200 mL of ethyl acetate and washed successively by 2 x 100 mL of saturated aqueous sodium bicarbonate, 2 x 100 mL of saturated aqueous sodium chloride and 2 x 100 mL of ...

Embodiment 2

[0059] Embodiment 2: the synthesis of phenylethyl alcohol glycoside

[0060] Take 1 g of the tetraacetylglucose phenylethanol prepared in step 1 and put it into a three-necked flask, and add 20 mL of methanol into it, and stir well to form a uniform suspension. 15 ml of a methanol solution containing 0.1 g of sodium methoxide was slowly added to the suspension, and further stirred for 60 minutes to fully react. After the reaction was complete, methanol was removed by rotary evaporation, and the residue was separated by silica gel column chromatography using ethyl acetate-methanol (15:1 volume ratio) as eluent. Fractions were monitored by thin layer chromatography (TLC) using ethyl acetate-methanol (8:1 volume ratio) as eluent. fractionation section with R f =0.51 were collected together and evaporated to give the product as a white solid which was recrystallized from appropriate amount of methanol in 92% yield.

Abstract

The invention discloses an electronic cigarette liquid containing phenylethanol glycosides. The electronic cigarette liquid is prepared from components in percentage by weight as follows: 3%-10% of tobacco leaf extract, 3%-8% of tobacco essence, 1%-5% of tobacco flavors, 5%-15% of deionized water, 10%-20% of glycerin, 3%-10% of phenylethanol glycosides and the balance of propylene glycol; the phenylethanol glycosides are prepared with a preferred chemical synthesis method. The method for preparing the phenylethanol glycosides is environment-friendly, rapid and efficient, the glycosides can promote electronic cigarette smoke to be fine, the drying stimulation is reduced, the smoking comfort is improved, the fragrance characteristic of an electronic cigarette can be further enhanced, the electronic cigarette liquid is used for electronic cigarette atomization, no tar or CO is produced, danger to consumers is greatly reduced, and damage of second hand smoking cannot be caused.

Description

technical field [0001] The invention belongs to the field of daily chemical industry and relates to tobacco, in particular to an electronic cigarette liquid containing phenylethyl alcohol glycoside. Background technique [0002] With the continuous development of the global tobacco control campaign, smoking and health have attracted more and more attention from the society. In order to meet the smoking and health requirements of different consumers, new tobacco products have developed rapidly in recent years, mainly including smokeless tobacco products, low-temperature cigarettes and e-cigarette. Among them, electronic cigarettes do not produce harmful substances such as tar, and the atomized smoke liquid is quickly diluted in the air. There is no sidestream smoke and no second-hand smoke hazards. It is a popular substitute for cigarettes. [0003] The appearance of electronic cigarettes is similar to that of ordinary cigarettes. It is a device that can vaporize nicotine so...
