Abstract: | A novel cigarette essence, menthyl (3-methyl)pentanoate, was synthesized. The structure of product was characterized by IR , GC- MS and 1HNMR. The influences of reaction factors ( reaction time, reaction temperature, the ratio of amount of catalyst and amount of the react- ants substance of and other factors)were also discussed and optimized. The optimum preparation conditions were n ((3-methyl) pentanoate ) : n (menthol) = 1.5: 1, benzene as the dewatering reagent, toluane-p-sulfonic acid as catalyst,w (toluene-p-sulfonic acid) 3% , reaction tempera- ture 130℃ and reaction time 5 h. The yield was 73.5%. |
