Abstract
The present invention relates to a process for extracting solanesol from tobacco, which is characterized in that a supercritical fluid extraction technique is used for extracting and separating solanesol from tobacco leaves. The present invention has the advantages of little solvent consumption, short production period, high yield, simple refining process, no environmental pollution and low production cost.
Description
The present invention relates to a kind of raw material extraction process, specifically the extraction process of eggplant Buddhist nun alcohol.
Eggplant Buddhist nun alcohol is the raw material of semi-synthetic medicine Coenzyme Q10 99.0, adopts organic solvents such as gasoline, sherwood oil extracting and separating and getting from tobacco leaf at present.Operational path is: tobacco leaf is pulverized, and adds 5-10 organic solvent lixiviate doubly, 3 times repeatedly, each a few hours, vat liquor reclaims solvent and gets thick product, and thick product generally contains eggplant Buddhist nun alcohol below 20%, color and luster is pitch black, and behind decolorizing and refining, the product that must contain eggplant Buddhist nun alcohol 70-80% is sold.The extraction yield of this technology eggplant Buddhist nun alcohol is below 80%, and the per kilogram tobacco leaf consumes 1 kilogram of solvent.Crude extract just gets purified product after sweeping multiple processing and decolorizing with activated carbon with methyl alcohol or ethanol.Every batch of raw material production cycle is more than 20 hours, and safety coefficient is low, contaminate environment.
The purpose of this invention is to provide a kind of supercritical liquid extraction technique that utilizes and come eggplant Buddhist nun alcohol in the extraction separation tobacco leaf, overcome many shortcomings of existing organic solvent method, save a large amount of organic solvents, shorten the production cycle, the eggplant Buddhist nun ethanol-extracted technology that extraction yield is high.
Technical scheme of the present invention is: come eggplant Buddhist nun alcohol in the extraction separation tobacco leaf with supercritical liquid extraction technique.
Described supercritical liquid extraction technique is that the pulverizing tobacco leaf is packed in the extractor, carbon dioxide liquid in the storage tank is pressurized to 10.0-30.0MPa, deliver to interchanger, send into extractor after carbon dioxide liquid in the interchanger is heated to 30-80 ℃ and finish extraction process delivering to after the pressurization; The CO 2 fluid of load solute enters in the separator, pressure is below the 8.0MPa in the separator, temperature is more than 10 ℃, CO 2 fluid solubleness reduces, and extract is separated, behind the separating and extracting thing, CO 2 fluid is again after interchanger liquefaction, get back in the storage tank recycling, product is emitted from the outlet of separator below, and every batch of raw material continuous extraction time is 2-4 hour.The whole process of this technology is the continuous extraction process, and products obtained therefrom is a crude product, and it contains eggplant Buddhist nun alcohol more than 40%, the color and luster cadmium yellow is passed through the smart product that simple treating process (prior art) can obtain containing eggplant Buddhist nun alcohol 70-80% again, and eggplant Buddhist nun ethanol-extracted rate is greater than 90%, the safety coefficient height, environmental pollution is little.
The present invention has following positively effect compared with the prior art: (tabulation is compared as follows)
| Organic solvent method | Supercritical CO 2Method | |
| Solvent consumption | Solvent cycle is used, but one kilogram of solvent of per kilogram raw material consumption | CO 2Recycle, consumption is few |
| Coal consumption | Greatly | Need not |
| Power consumption | Little | Greatly |
| The batch of material production cycle | More than 20 hours | 2-4 hour |
| The extraction yield | 80％ | 90％ |
| Thick product purification | Relative complex | Easy |
| Production cost | High | Low relatively |
| The three wastes produce | Have | Do not have |
Though the supercritical carbon dioxide process power consumption is bigger, the formed cost of power consumption still is starkly lower than organic solvent method solvent consumption and the formed cost of coal consumption.
Fig. 1 is technological process apparatus figure of the present invention
Among the figure, 1-storage tank, 2-high-pressure pump, 3-interchanger, 4-extractor, 5-separator, 6-interchanger.
Embodiment: will pulverize tobacco leaf and pack in the extractor, carbon dioxide liquid in the storage tank 1 is pressurized to 20.0MPa by high-pressure pump 2, deliver in the interchanger 3, finish extraction process delivering to after the pressurization to send in the extractor 4 after carbon dioxide liquid in the interchanger is heated to 50 ℃; The CO 2 fluid of load solute enters in the separator 5, pressure is 2.0MPa in the separator, temperature is 10 ℃, behind the temperature, pressure, solubleness reduces, and extract is separated in the change separator, behind the separating and extracting thing, CO 2 fluid after interchanger 6 liquefaction, gets back in the storage tank recycling again, and product is emitted from the outlet of separator below.This product is a crude product, and crude product adds 5-10 and doubly measures methyl alcohol, and the heated and stirred after-filtration folds precipitation after filtrate is freezing, and filtering-depositing is dry must smart product.
