Abstract
The present invention is dry distillation process of extracting nicotine from tobacco stem. Crushed tobacco stem is heated in dry distiller in condition of isolating air. The present invention features that water fog produced during dry distillation is pumped with vacuum pump to pass through four containers successively, with one buffer being set between the last container and the vacuum pump. The four containers have water amount ratio of 6 to 5 to 4 to 3 successively, and after dry distillation for 8-10 hr, the brown oily saturated liquid inside the No. 1 container is collected as the destination product while shifting water inside the next containers forwards successively for the next time of dry distillation. Compared with available technology, the present invention has simple technological process, no acid and alkali corrosion and no solvent to be recovered, and the product has high ether content and high pesticidal effect.
Description
Technical field
The present invention relates to a kind of from tobacco the method for extraction nicotine, relate in particular to a kind of method with dry distillation extraction nicotine from tobacco stem.
Background technology
It is a kind of main alkaloid in the tobacco that nicotine has another name called Nicotine (its Latin is nicotinum), and its molecular formula is C
10H
34N
2, be colourless or pale yellow oily liquid, in air, become brown, on the agricultural as sterilant.Document record is flooded tobacco with dilute sulphuric acid, with the alkali neutralization, and vapor distillation then, and with oxalic acid treatment, row alkalization and getting again.Chinese patent literature discloses the many pieces of methods about extraction nicotine from tobacco.Wherein application number 89104689 is announced a kind of production method of nicotine sulfate: tobacco is pulverized water, alkali steeping, and its filtrate is with the solvent oil extracting and separating of 50-120 degree, adds the sulfuric acid of 10-80% to above-mentioned solvent oil, and layering separates.The pollution that this method exists acid, caustic corrosion and may cause, complex process, process is many, and has problem such as organic solvent recuperation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, and a kind of method with dry distillation extraction nicotine from tobacco stem is provided.
The objective of the invention is to be achieved by following technical scheme.
A kind of method with dry distillation extraction nicotine from tobacco stem places dry distiller with the tobacco stem of a certain amount of drying and crushing, and the secluding air heating is characterized in that:
The smog that produces in the destructive distillation successively through at least 4 water containers, is provided with the snubber that is communicated with it between the container at end and vacuum pump under the vacuum pump effect; In the said vesse Total Water be used tobacco stem quality 2.0-3.0 doubly, wherein the ratio of the quality of water is 6: 5: 4 in No. 1 to No. 4 container: 3; During non smoke, stop destructive distillation, collect the brown oily saturated solution purpose product in the container No. 1.
The method of above-mentioned extraction nicotine, in its 1-4 container Total Water be the tobacco stem consumption 2.2-2.6 doubly;
The method of above-mentioned extraction nicotine successively adds in the last separately container successively with containing nicotine water in No. 2-No. 4 containers before next destructive distillation, and mends in the 1-4 container respectively and add water to requirement.
The ratio of the water yield is suitable in water consumption of the present invention and the container, and 1-4 number the interior water yield of each container is successively decreased, and plays cooling effect, and nicotine is soluble in water in the smog, the state that reaches capacity, and the consumption and the transport power that reduce packaging vessel increase; Continue dissolving in the container in the back at the undissolved nicotine of last container, prevent to take out of container, help quiet run.The container multioperation is steady, but long flow path.
The present invention compared with prior art has following advantage:
1. technology simple possible, flow process is short, the organic solvent-free removal process;
2. anacidity, caustic corrosion and the pollution that may cause;
3. after the each destructive distillation of the present invention finishes, collects No. 1 brown oily saturated solution product in the container after, priority adds to nicotine-containing water in the 2-4 container in the last separately container and recycles successively;
4. nicotine content is 2.30 milligrams in 1 liter of brown saturated solution, contains the ethers height in the product, and insecticidal effect is better.
