Embodiment 1

[0035] Preparation of tobacco humectant Uio-66 by solvothermal method:

[0036] 15mmol anhydrous ZrCl 4 Put it into a beaker, add 30ml of N,N'-dimethylamide, and then perform ultrasonic treatment for 30 minutes until it is completely dissolved. Add 15mmol terephthalic acid and 60ml N,N'-dimethylamide into the above solution, and continue to sonicate for 30 minutes until completely dissolved. The above mixed solution was transferred into a polytetrafluoroethylene reactor and reacted at 120°C for 24h. Filter out the solid product, wash it with 20ml of 60°C ethanol, dry it, transfer it to a conical flask, add 30ml N,N'-dimethylamide and stir to remove unreacted ligand. The above-mentioned product was filtered out, washed with 20ml of ethanol, dried and transferred to a reaction kettle, and then dried in an oven at 90°C for 12 hours. The solid product was obtained by centrifugation, and was centrifugally washed twice with 20 ml of ethanol and twice with 20 ml of acetone, and th...

Embodiment 2

[0037] Embodiment 2: Preparation of tobacco humectant Uio-66-NH by solvothermal method 2

[0038] 18mmol anhydrous ZrCl 4Put it into a beaker, add 30ml of N,N'-dimethylamide, and then perform ultrasonic treatment for 30 minutes until it is completely dissolved. Add 14mmol of 2-amino-terephthalic acid and 50ml of N,N'-dimethylamide into the above solution, and continue ultrasonic treatment for 30 minutes. The above mixed solution was transferred into a polytetrafluoroethylene reactor and reacted at 120°C for 24h. Filter out the solid product, wash it with 20ml of 60°C ethanol, dry it, transfer it to a conical flask, add 30ml N,N'-dimethylamide and stir to remove unreacted ligand. The above-mentioned product was filtered out, washed with 20ml of ethanol, dried and transferred to a reaction kettle, and then dried in an oven at 90°C for 12 hours. The solid product was obtained by centrifugation, and was centrifugally washed twice with 20 ml of ethanol and twice with acetone, a...

Embodiment 3

[0040] Embodiment 3: the mensuration of the dynamic content of moisture added in tobacco by tobacco humectant Uio-66

[0041] Dissolve the tobacco humectant Uio-66 prepared in Example 1 in a mixed solvent of 1,2-propanediol and glycerin, and add it to shredded tobacco according to the amount of humectant at 0.2%, so as to add an equal amount of alcohol mixed solvent but not Cut tobacco samples containing humectant Uio-66 were used as blank control. Then the shredded tobacco sample was placed in a DVS dynamic moisture adsorption instrument with a temperature of 22° C. and a relative humidity of RH46%, to measure the dynamic moisture content. The results are shown in Table 1 and Figure 4 shown. From Figure 4 It can be seen that the adsorption-desorption curve of Uio-66 has a large adsorption hysteresis. Under a certain pressure, it has a certain degree of adsorption and retention of water, and the maximum adsorption capacity can reach 14%, which has a good water adsorption ...

Abstract

The invention discloses a tobacco moisturizer. The tobacco moisturizer is a metallic organic skeleton material with a three-dimensional structure obtained through the self-assembling of Zr 4+ and p-phthalic acid or 2-aminobenzene-1,4-dicarboxylic acid, wherein the metallic organic skeleton material with a three-dimensional structure obtained by the self-assembling of the Zr 4+ and the p-phthalic acid is Uio-66, and the metallic organic skeleton material with a three-dimensional structure obtained by the self-assembling of the Zr 4+ and the 2-aminobenzene-1,4-dicarboxylic acid is Uio-66-NH2. The invention further discloses a preparation method of the tobacco moisturizer and the application of the tobacco moisturizer in tobacco.

Description

technical field [0001] The invention belongs to the field of tobacco additives, and in particular relates to a tobacco humectant, its preparation method and application. Background technique [0002] Tobacco leaf is a loose and porous material, and from a thermodynamic point of view, it has a high potential for absorbing moisture. Just because it is a porous material, free moisture, capillary moisture, etc. will be lost faster at higher temperature and lower humidity, so that cigarettes are also easy to dry. In the production process of cigarette products, the addition of humectant can maintain the moisture of cut tobacco and improve its physical moisturizing performance. [0003] At present, commonly used humectants are polyols such as propylene glycol, glycerin, diethylene glycol, and sorbitol. However, these humectants are unsatisfactory in improving the sensory quality of cigarettes. Therefore, a new type of humectant is needed to replace the traditional humectant, re...
