Embodiment 1

[0025] Embodiment 1: the preparation method of modified activated carbon

[0026] 1. Activation:

[0027] Reagents: activated carbon; potassium permanganate; concentrated sulfuric acid; concentrated phosphoric acid; hydrogen peroxide; deionized water

[0028] (1) At room temperature, mix 100-500mg of activated carbon with potassium permanganate (500-2000mg) and add it to a 100-250mL round bottom flask. After stirring evenly, add 20-100mL of concentrated sulfuric acid-concentrated phosphoric acid to the reaction flask dropwise For the mixed acid solution (volume ratio 1:1-9:1), the rate of addition is properly controlled so that the temperature of the reaction solution is controlled within 30 degrees Celsius in a cold water bath.

[0029] (2) After the acid solution is added dropwise, transfer it to a constant temperature device and react at 50 degrees for 8-48 hours.

[0030] (3) After the reaction is over, cool the reactant to room temperature naturally, then pour it into i...

Embodiment 2

[0035] Add 80g of Burley tobacco powder to 600ml of 15% tartaric acid solution and heat at 70°C for 2 hours. After cooling, filter the filter residue. Use 40% KOH solution to adjust the pH of the filtrate to > 11, and then use 700ml of n-hexane + ethyl acetate Ester (5:1) was extracted twice, and the organic phases were combined, concentrated and evaporated to dryness to obtain free nicotine. The nicotine component in the free nicotine contains more than 80%, even up to 95%, which also contains the aromatizing components of the gas in the tobacco. Of course, the free nicotine component can also be obtained through compounding.

[0036] Dissolve free nicotine in the atomizer (propylene glycol) to prepare electronic cigarette liquid, wherein each gram of electronic cigarette liquid contains about 8mg of nicotine.

Embodiment 3

[0038] The above-mentioned free nicotine and tartaric acid are dissolved in an atomizing agent (propylene glycol) to prepare an e-cigarette liquid, wherein each gram of the e-cigarette liquid contains about 8 mg of nicotine and 2 mg of tartaric acid. The added tartaric acid can form nicotine tartrate salt with nicotine.

Abstract

The invention provides electronic cigarette liquid stably releasing cigarette fragrance. The electronic cigarette liquid contains nicotine, nicotine salt, an aroma component, an atomization componentand modified activated carbon. A preparation method of the modified activated carbon comprises the steps that the activated carbon and potassium permanganate perform reaction after being mixed under the acidic condition, excessive potassium permanganate is removed after the reaction is completed, the obtained solid product is washed to reach a neutral state, and then p-toluenesulfonic acid and polyethylene glycol perform esterification reaction to obtain the modified activated carbon. The modified activated carbon and organic acid are added into the electronic cigarette liquid to be combined with the nicotine, various components in the electronic cigarette liquid are absorbed to form the nicotine salt, the slow-release purpose is achieved, and the nicotine can be stably and uniformly released.

Description

technical field [0001] The invention relates to an electronic cigarette liquid for stably releasing cigarette aroma, belonging to the technical field of electronic cigarettes. Background technique [0002] In recent years, new tobacco products such as low-temperature cigarettes and electronic cigarettes are rapidly emerging. The shape of electronic cigarettes is similar to that of ordinary cigarettes. It is a device that can vaporize electronic cigarette liquid (also known as electronic cigarette oil, which is a flavor solution) into mist, giving smokers a feeling similar to smoking. [0003] While satisfying people's smoking habits, electronic cigarettes greatly reduce the harm to human body. In a nutshell, electronic cigarettes have the following main features: First, they do not need to be burned, which greatly reduces the tar and harmful components produced by burning, and are less harmful than traditional cigarettes; second, they do not produce second-hand smoke and do...
