Description
Technical field
The present invention relates to the method that lanolin non-catalysis hydrolyzation in a kind of near critical aqueous medium prepares lanoceric acid and Wool wax alcohol.
Background technology
Lanolin is the oiliness secretory product of lamb skin adipose gland, attached to wool surface.Produce the organic waste water that contains lanolin in a large number in woollen mill's waste water from washing wool, lanolin is because saponification becomes the suspension emulsified state with emulsifying effect, and is highly muddy, if directly discharging is not only wasted resource but also can be produced severe contamination to environment.Therefore from waste water from washing wool, reclaim lanolin and develop related products and can reduce pollution greatly, have good economic worth again environment.
The derivative product that is developed by lanolin has had tens kinds, wherein most of products with lanoceric acid and Wool wax alcohol by means such as acetylize, epoxy alkylization, esterification in addition modification form.Therefore be a vital step by set out preparation lanoceric acid and Wool wax alcohol of lanolin to the development and use of lanolin.
Lanoceric acid not only can be directly as tensio-active agent, and can be used as the additive of the cosmetics of super quality.The emulsifying capacity of lanoceric acid, emulsifying stability and water-retentivity are all very strong, and skin is also had the effect of well moistening, and can promote the infiltration of water vapour to skin fat; Metallic soap and the soap analog derivative made by lanoceric acid are a kind of good oleophilic emulsifier and metal antirusting agent.
Contain a large amount of sterols materials in the Wool wax alcohol, as cholesterol, triterpene alcohol etc., can be used as nutrition agent and biologically active substance joins in the cosmetics of super quality, also can in the W/O cosmetic formulations, be used as emulsifying agent, co-emulsifier and reverse emulsive stablizer, skin is had good affinity and wettability.Wherein cholesterol is not only the important source material of liquid crystal industry; or the important intermediate of medicine industry; can be used for synthesis of vitamin d 3, artificial Calculus Bovis etc.; cholesterol can make nearly all steroid hormone medicine as a kind of natural steroid resource of steroid drugs by chemistry or microbial conversion process.The raw materials for production of China's steroid drugs still rely on resource so far and are on the brink of exhausted Chinese yam, so the sterol development of resources is extremely urgent.
At present, the method for hydrolysis of lanolin mainly contains the alkaline saponification method and changes esterification process.Saponification method mainly contains the alkali aqueous solution saponification method, alkali aqueous solution adds auxiliary agent saponification method and alkali alcoholic solution saponification method etc.; Changeing esterification process is that reactions such as lanolin and methyl alcohol are generated lanoceric acid methyl esters and Wool wax alcohol.At present domestic still based on alkali saponification method, there are problems such as lanoceric acid soap and Wool wax alcohol separation difficulty, complex process and process instability, quality product be relatively poor in this method.
(Near Critical Water NCW) typically refers to the compressed liquid water of temperature between 200~350 ℃ to near-critical water.Water has following three key properties in this zone:
1) depresses at saturated vapo(u)r, the ionization constant of NCW has a maximum value to be about 10-11 (mol/kg) 2 near 275 ℃, its value is 1000 times of normal temperature and pressure water, and ionization constant increases with the increase of pressure, [H3O+] among the NCW and [OH-] are near weak acid or weak base, therefore the function that self has acid catalysis and base catalysis can make some acid-base catalyzed reaction needn't add acid base catalysator, thereby avoid the neutralization of soda acid, the operations such as processing of salt;
2) depress at saturated vapo(u)r, the specific inductivity of 20 ℃ of water is 80.1, and has only 23.5 275 ℃ the time.Although the specific inductivity of NCW is still bigger, solubilized even ionized salts, but it is enough little with dissolved organic matter, the density that adds NCW is big, and (275 ℃ of saturated vapo(u)rs density of depressing water is 0.76g/cm3, the specific inductivity of NCW, density and acetone are close), therefore NCW has extraordinary solubility property, has the characteristic of energy while dissolved organic matter and inorganics.This can carry out the building-up reactions in many NCW media in homogeneous phase, thereby eliminates resistance to mass transfer, improves speed of response, and the reaction back only needs simple cooling just can realize separating of hydrolysate and water simultaneously, and water can be recycled;
3) physicochemical property such as the specific inductivity of near-critical water, ion-product constant, density, viscosity, spread coefficient, solubleness are adjustable continuously in the scope of broad with temperature, pressure, the rerum natura that is near-critical water has controllability, therefore as reaction medium, near-critical water has different solvent properties and reactivity worth at different states.
The present invention is applied to near-critical water on the non-catalysis hydrolyzation of lanolin as reaction medium, utilize the characteristic of near-critical water to realize no catalysis, efficient, the green hydrolysis of lanolin, and then utilize lanoceric acid to separate with the difference on the Wool wax alcohol rerum natura.
Summary of the invention
The purpose of this invention is to provide a kind of green, the lanolin non-catalysis hydrolyzation prepares the method for lanoceric acid and Wool wax alcohol in the near critical aqueous medium efficiently.
The step of method is as follows:
1) add deionized water and lanolin in autoclave, deionized water and lanolin mass ratio are 1: 1~6: 1, open stirring, are warming up to boiling under the normal pressure, open vent valve 2~5min;
2) continue to be warming up to 200~350 ℃ of hydrolysis 1~8h;
3) hydrolysate cooling back solid-liquid separation adds the calcium chloride saturated aqueous solution in the solid phase, stirs 10~60min, is warming up to 70~80 ℃, static back oily water separation;
4) oil reservoir is used organic solvent extraction after washing, and extracting phase is a lanoceric acid calcium, after acidifying the lanoceric acid product, extraction phase through concentrate, must the Wool wax alcohol product after the crystallization.
The purpose that " is warming up to 100 ℃, opened vent valve 2~5 minutes " in the step 1) of the present invention is to utilize water vapour to take away the interior oxygen of still, to reduce the generation of side reaction, improves the yield of product.The consumption of calcium chloride saturated aqueous solution is advisable with 1.1~1.3 times of theoretical consumption in the step 4).
The present invention need not add any catalyzer in reaction process, self acid-base catalysis characteristic of utilizing near-critical water makes lanolin hydrolysis in near-critical water generate lanoceric acid and Wool wax alcohol with characteristic that can dissolved organic matter, solved the pollution problem of existing method serious environmental, reaction process is simple, product yield is higher, and has realized the greenization of production process.
