Embodiment 1

[0019] Dissolve 6g of menthone in a mixed solvent (2:3) composed of 50mL of absolute ethanol and benzene, add 20g of anhydrous sodium carbonate; weigh 4g of hydroxylamine hydrochloride, dissolve in 50mL of ethanol, and gradually Add it dropwise to the menthone solution, reflux for 4 hours after the addition, filter after cooling, and recover the solvent (5.33KPa) by vacuum distillation to obtain about 3.5 g of the crude menthone oxime, which is recrystallized in absolute ethanol solution and further purified to obtain white crystals .

[0020] Add sodium amide and liquid ammonia (cooled by liquid nitrogen and acetone bath) into a 500mL dry three-necked flask, drop the mixture of propionitrile and 2-bromopropane (3:4) into the flask, and keep the temperature to continue the reaction a period of time. After the reaction is over, allow it to heat up naturally, and after all the liquid ammonia has volatilized, add a small amount of water to quench the reaction. An appropriate am...

Abstract

The invention discloses a sustained-release pellet capsule of a sweet cooling agent for a cigarette with a filter plug, belonging to the technical field of cigarettes. The sustained-release pellet capsule of the sweet cooling agent for the cigarette with the filter plug is prepared by the following steps of: (1) synthesizing corn mint oxime and N,2,3-trimethyl-2-isopropyl-butyrylamide; (2) compounding the corn mint oxime and the N,2,3-trimethyl-2-isopropyl-butyrylamide according to the proportion of (5-20): (1-10) to obtain a uniformly mixed white crystal compound; and (3) dropping. The invention has the advantages that the sustained-release pellet capsule prepared through synthesizing, compounding and dropping releases sweet substances only when the cigarette is smoked, therefore, effective components can not be lost in advance, and better fragrance keeping and remaining effects can be achieved. Meanwhile, the sweet and fragrant taste is unique and is coordinated with the smoke. In the process that the cigarette is smoked, the characteristic of a sweetener can be better embodied, the quality of the smoke is not remarkably influenced, and raw materials used in the invention have wide sources and low cost.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a sweet-flavored cooling agent prepared as a sustained-release capsule for a filter tip. Background technique [0002] In the prior art, sweeteners are generally applicable to all tobacco products, and are especially suitable for cigarettes with low sugar content, high nicotine content and high pH value of smoke. Traditional sweeteners include white sugar, brown sugar, honey, glucose, maltose, fructose, etc. Generally, sweeteners are used in cigarette fillings, and sweeteners in shredded tobacco will participate in combustion at the same time as the cigarette is drawn, not only losing Due to the effect of sweetening and flavoring, new harmful substances may also be produced due to cracking. It is added to the filter rod, so that it releases the sweet substance into the mainstream smoke during the smoking process of the cigarette, and endows the cigarette with a sp...
