Embodiment 1
[0053] Mix 6.00 g of leaf alcohol, 3.42 g of δ-caprolactone, and 50 mg of citric acid in a 50 mL single-necked bottle, and stir and react at 70° C. for 3 h. GC-MS detection reaction progress. After the reaction was completed, 3.63 g of 5-hydroxyhexanoic acid phyllyl ester was obtained through column chromatography separation and purification. The yield was 56%.
[0054] Get 3g of 5-hydroxyhexanoic acid phyllyl ester, dissolve in 997g of absolute ethanol and configure a 0.3% solution, then dilute the ethanol solution with 9000g of water to obtain a 0.03% solution by mass, and this solution is the coating solution .
[0055] The coating liquid was coated on the cigarette paper by off-line gravure coating, the speed of the coating machine was controlled at 60 m / min, and the temperature of the oven was controlled at 90°C. In cigarette paper, the amount of 5-hydroxyhexanoic acid phyllyl ester accounts for about 0.005% of the cigarette paper.
[0056] Take cut tobacco of a certa...
Embodiment 2
[0059] Using a method similar to that of Example 1, geraniol 3-(2-hydroxyphenyl)propionate was prepared by carrying out a transesterification reaction of geraniol and dihydrocoumarin under acidic conditions.
[0060] Get 3g 3-(2-hydroxyphenyl) geraniol propionate, be dissolved in 997g absolute ethanol and be configured into a 0.3% solution, then add 9000g water to dilute the obtained ethanol solution to obtain a coating with a mass percentage of 0.03%. cloth liquid. Add it to the cigarette paper by off-line gravure coating, the speed of the coating machine is controlled at 60m / min, the temperature of the oven is controlled at 100°C, and the product containing 3-(2-hydroxyphenyl) geraniol propionate The amount of 3-(2-hydroxyphenyl) geraniol propionate added to the cigarette paper accounts for about 0.005% of the cigarette paper.
[0061] Take cut tobacco of a certain low-tar specification and roll it with the above-mentioned cigarette paper to make a cigarette, and the compar...
Embodiment 3
[0064] Using a method similar to Example 1, 3-(2-hydroxyphenyl) phyllyl propionate was prepared.
[0065] Take 0.1 g of 3-(2-hydroxyphenyl) phyllyl propionate, dissolve it in 50 g of absolute ethanol, and then add 950 g of water to dilute to prepare a 0.01% solution. Cigarette paper was soaked therein for 10 minutes, and after soaking, the paper was dried at room temperature, and dried to obtain cigarette paper containing 3-(2-hydroxyphenyl) phyllyl propionate, 3-(2-hydroxyphenyl ) The added amount of phyllopropionate accounts for about 0.15% of the cigarette paper.
[0066] Take cut tobacco of a certain low-tar specification and roll it with the above-mentioned cigarette paper to make cigarettes, and the comparison is a cigarette made of the same cut tobacco and cigarette paper without adding 3-(2-hydroxyphenyl) phyllyl propionate. The test found that during the smoking process of the cigarette loaded with the case cigarette paper of the present invention, 3-(2-hydroxyphenyl...
