Embodiment 1

[0023] S1. Pretreatment of tobacco waste: first, pour the selected tobacco waste into the boiler dryer, rotate and dry for 1.5 hours at a speed of 60r / min and a temperature of 75°C, so that the moisture in the tobacco waste can be fully evaporated , and then pour the dried tobacco waste into the crushing and grinding machine, first knock and crush it, and at the same time screen through a 90-mesh screen, and the tobacco waste that passes through the screen will enter the grinding chamber of the crushing and grinding machine. Fully grind through the grinding wheel, and the tobacco waste powder after grinding will be discharged from the discharge port of the crushing and grinding machine, and people can collect the tobacco waste powder discharged from the discharge port;

[0024] S2. Nicotine dissolution treatment: Pour the mixture of the tobacco waste powder obtained in S1, the prepared NaOH solution and methyl tert-butyl ether into the mixing container in turn, then put the mix...

Embodiment 2

[0030] S1. Pre-treatment of tobacco waste: first, pour the selected tobacco waste into the boiler dryer, rotate and dry for 1 hour at a speed of 50r / min and a temperature of 70°C, so that the moisture in the tobacco waste can be fully evaporated. Then pour the dried tobacco waste into the crushing and grinding machine, first knock and crush it, and at the same time screen it through an 80-mesh screen. The tobacco waste that passes through the screen will enter the grinding chamber of the crushing and grinding machine. The grinding wheel is fully ground, and the tobacco waste powder after grinding will be discharged from the discharge port of the crushing and grinding machine, and people can collect the tobacco waste powder discharged from the discharge port;

[0031] S2. Nicotine dissolution treatment: Pour the mixture of the tobacco waste powder obtained in S1, the prepared NaOH solution and methyl tert-butyl ether into the mixing container in turn, then put the mixing contain...

Embodiment 3

[0037] S1. Pre-treatment of tobacco waste: first, pour the selected tobacco waste into the boiler dryer, rotate and dry for 2 hours at a speed of 70r / min and a temperature of 80°C, so that the moisture in the tobacco waste can be fully evaporated. Then pour the dried tobacco waste into the crushing and grinding machine, first knock and crush it, and at the same time screen it through a 100-mesh screen. The tobacco waste that passes through the screen will enter the grinding chamber of the crushing and grinding machine, The grinding wheel is fully ground, and the tobacco waste powder after grinding will be discharged from the discharge port of the crushing and grinding machine, and people can collect the tobacco waste powder discharged from the discharge port;

[0038] S2. Nicotine dissolution treatment: Pour the mixture of the tobacco waste powder obtained in S1, the prepared NaOH solution and methyl tert-butyl ether into the mixing container in turn, then put the mixing contai...

Abstract

The invention discloses a method for extracting R-nicotine from tobacco waste, which specifically includes the following steps: S1, pretreatment of tobacco waste, S2, nicotine dissolution treatment, S3, alkaline racemization treatment, S4, Chiral resolution of nicotine, S5, extraction and separation, S6, purification and refining of R-nicotine, the present invention relates to the technical field of extraction of tobacco chemical components. The method for extracting R-nicotine from tobacco waste realizes improving the racemization rate of S-nicotine by selecting different racemic agents, selecting a new resolution agent to improve the conversion rate of the target product, and using a ratio extractant to increase the Product purity and energy saving and pollution reduction optimization test, compared the advantages and disadvantages of the preparation route for pilot production, improved the extraction yield and the purity of R-nicotine, thus replacing the traditional crystallization enzymatic method to extract R-nicotine, which is very convenient People's R-nicotine extraction work.

Description

technical field [0001] The invention relates to the technical field of extraction of tobacco chemical components, in particular to a method for extracting R-nicotine from tobacco waste. Background technique [0002] Tobacco annual or limited perennial herb, Solanaceae. The plant is covered with glandular hairs, the stem height is 0.7-2 meters, the petiole is not obvious or has a winged stalk, the panicle is terminal, the calyx is cylindrical or cylindrical bell-shaped, the corolla is funnel-shaped, and the end is pink. Whether and how to choose tobacco leaves, Basically, the grade quality of tobacco leaves is an important basis, and the grade quality of tobacco leaves depends on the quality and purity of grades when receiving. Therefore, tobacco leaf reception plays a very important role in tobacco leaf selection, and tobacco leaf reception, selection supervision and supervision are likely It is the same group of people, so it is not only responsible to the company but also...
