Embodiment Construction

[0016] Essence for tobacco of the present invention, take 3-methylpentanoic acid and menthol as raw material, and reaction formula is as follows:

[0017]

[0018] The substance ratio of 3-methylpentanoic acid to menthol is 1.5:1.

[0019] The preparation method of flavoring essence for tobacco of the present invention comprises the following steps: using 3-methylvaleric acid and menthol as raw materials, wherein, the ratio of substances of 3-methylvaleric acid to menthol is 1.5:1, and using benzene As a water-carrying agent, the catalyst is p-toluenesulfonic acid, the reaction heating temperature is 130°C, the reaction time is 5h, and the reaction produces menthyl 3-methylvalerate, wherein the consumption of the catalyst p-toluenesulfonic acid is The reactant 3-methylpentanoic acid and menthol substances amount and 3%.

Abstract

The invention relates to a cigarette-used essence and a preparation method thereof, which takes 3-methyl-pentanoic acid and menthol as raw materials, wherein, the quantity ratio of 3-methyl-pentanoic acid and menthol is between 1.25 to 1 and 2.25 to 1. Benzene is taken as a water-carrying agent and methyl-benzenesulfonic acid as a catalyst; heating temperature for reaction is between 120 DEG C and 140 DEG C; time for reaction is 1h to 6h; 3-methyl-menthyl valerate is obtained. The 3-methyl-menthyl valerate, namely the cigarette-used essence, is a novel menthyl subtane with potential fragrance; ester prepared from 3-methyl-pentanoic acid and natural product menthol belongs to a mentholated essence in terms of the odor type and structure and has lower volatility than menthol; and therefore, after entering cigarettes during essence adding process, the ester slowly decomposes during the burning process of the cigarettes and then evenly releases 3-methyl-pentanoic acid and menthol, thereby realizing the purpose of balancing the pH value of the cigarettes and improving the aftertaste of the cigarettes and smoke quality of the cigarettes.

Description

technical field [0001] The invention relates to an essence for tobacco, and also relates to a preparation method of the essence for tobacco. Background technique [0002] Tobacco spices are used in the cigarette process to modify or cover up the defects of tobacco leaves, to compensate, enhance, adjust and improve the physical and chemical characteristics of cigarettes, to round out the aroma, to reduce the irritation of smoke, to make smoke smooth, to improve the taste and to increase the pleasantness of cigarettes. The aroma of human cigarettes can suppress the spicy stimulation and counteract the disgusting bad smell, reduce the harmful components of cigarettes, and meet the various requirements of consumers. my country is one of the earliest countries in the world to discover and use spices. The production of tobacco flavors in our country was roughly around the 1930s. With the recovery of the national economy and the development of the cigarette industry, new varieties...
