Abstract
The invention belongs to oil chemical technology, be a kind of be raw material enough with rapeseed oil foot or other vegetables oil, extract the processing method of lipid acid, grease and phosphatide.The present invention changes traditional technical process, adopts novel lixiviation process, is about to raw materials pretreatment and dewaters after the removal of impurities, adds polar solvent and leaches, and disposablely separates from raw material and extracts lipid acid, grease and phosphatide.Technology of the present invention is simple, and solvent is cheap and easy to get, and the product purity height does not produce the three wastes simultaneously, and environmentally safe has good economic benefits and social benefit.
Description
The invention belongs to oil chemical technology, relating to a kind of is that raw material extracts lipid acid, the processing method of grease and phosphatide with rapeseed oil enough.
China's rapeseed oil output has occupied the hat in the world, and rape oil will produce a large amount of rapeseed oil of foot material down foots when refining, and the past as fertilizer and feed, fully utilized mostly afterwards, therefrom produced lipid acid.
The rapeseed oil foot comprises water foot and soap foot, prior art is taked to add earlier caustic soda mostly and is mended fair saponification, add sulfuric acid acidation then to produce lipid acid, this method technology is simple, instant effect, but need to consume goods and materials caustic soda in short supply and use the very strong sulfuric acid of corrodibility, and another important component phosphatide (comprising Yelkin TTS and kephalin) fails to extract in the oil foot, emits in vain.
In order to obtain phosphatide from water foot, city, Chongming, Shanghai bridge oil factory takes the heating under vacuum method of enrichment to obtain phosphatide, but this method complex process, and energy consumption is very high, invest also greatly, and separates not thoroughly, still contains 30% the grease of having an appointment after separating in the phosphatide.
The objective of the invention is to change this conventional process flow fully, adopt novel leaching method, disposable can from the rape seed oil foot, the separation and extraction lipid acid, grease and phosphatide.
Main points of the present invention are: before formal the leaching, carry out pre-treatment earlier, promptly adopt the way of saltouing and flocculating that the oil foot is carried out initial gross separation, remove moisture and partial impurities, add polar solvent then, leach at a certain temperature, and the control extraction time, these solvent low toxicities or nontoxic, security is more superior than the classical solvent naphtha that uses, has the halogen-containing solvent that does not fire with flame retardant properties in order thoroughly to improve and to solve security, also can adding.Because grease is dissolved in the leaching solvent, and phosphatide is insoluble to it, then can disposablely obtain grease and phosphatide goods respectively.
The present invention has overcome in the prior art and to have separated thoroughly and can not disposable isolating shortcoming, technology is simple, safe and reliable, solvent is cheap and easy to get, the product purity height, raw materials used wide material sources, promptly available green oil foot obtains grease and phosphatide, also available displaying year for a long time, and even oil foot or " middle layer " of fermentation obtain lipid acid and phosphatide, and this is just wide than former traditional method suitability.Principle and technology also can be promoted and be used for other all vegetables oil foots in view of the above.The present invention also has a remarkable advantage, does not produce the three wastes, can not pollute environment.
Specific embodiments of the invention are:
Earlier the rapeseed oil foot is carried out pre-treatment, salt that need not be traditional when saltouing, and use saltcake or green vitriol instead, the latter has the effect of saltouing and flocculating concurrently, add-on accounts for 1～2% of raw material, or the two mixes then better effects if by a certain percentage, the blending ratio of saltcake and green vitriol is 1～5: 1, and pretreatment temperature is 50～90 ℃, and the time is 1～3 hour, leach behind filtering moisture content and the impurity, add and leach solvent acetic acid formicester or acetone, the ratio that leaches solvent and raw material is 0.5～1: 1, also can add halogen-containing solvent simultaneously, halogen-containing solvent is 0.1～0.4: 1 with the ratio that leaches solvent, 20～60 ℃ of extraction temperatures, 4～12 hours time, it is separated to leach the back raw material, its upper strata removes solvent and obtains grease, and its lower sediment thing is phosphatide.
Claims (5)
1, a kind of is raw material with rapeseed oil enough, extracts lipid acid, the method for grease and phosphatide, it is characterized in that: adopt lixiviation process, be about to raw material, add polar solvent and leach through saltouing and the pre-treatment of flocculating dewaters after the removal of impurities, disposable separation and extraction lipid acid, grease and phosphatide.
2, pre-treatment according to claim 1 is characterized in that saltouing and adopts saltcake or green vitriol when flocculating, and add-on is 1～2% of a raw material, or the former with the latter is by 1～5: 1 mixed, and pretreatment temperature is 50～90 ℃, and the time is 1～3 hour.
3, lixiviation process according to claim 1 is characterized in that the solvent that adopts is methyl acetate or acetone, and the ratio of solvent and raw material is 0.5～1: 1, and extraction temperature is 20～60 ℃, and extraction time is 4～12 hours.
4, lixiviation process according to claim 1 is characterized in that also can add halogen-containing solvent improves security, and add-on accounts for 10%～40% of solvent.
5, lixiviation process according to claim 1 is characterized in that this method is applicable to extraction and separation of fatty acids, grease and phosphatide from other vegetables oil foot.
