Description
Technical field
This patent relates to a kind of extracting method of cholesterol, and is specifically a kind of from adopting transesterificationization-short-path distillation-column chromatography-new crystalline technology, extracts the method for high net cholesterol from lanolin.
Background technology
Cholesterol is a kind of important medicine intermediate, can synthesis of vitamin d 3 by it, and a series of steroidal anti-inflammatory class medicine; In addition because cholesterol makes it become indispensable substance in the cosmetics of super quality to the skin excellent lubricating properties.At present the approach of producing of cholesterol roughly has two: the one, from the brain stem of animal, internal organ, extract; The one, from lanolin, extract.Because there is doubt in Disease-causing gene among the animal organ to the mankind's potential hazard, and last approach is subjected to the restriction of world market day by day and is replaced by the latter gradually.
Lanolin is to be secreted and be attached on Ester on the wool by the sheepskin adipose gland, can reclaim acquisition from waste water from washing wool.The lanolin fatty acid of separating from lanolin has kind more than 30 approximately, and wherein straight-chain acid content is less, and branched acids content is more, accounts for about 9.5% and 60% of fatty acid total amount respectively.Also have alcohol acid in addition, account for 28% of fatty acid total amount.Contained fatty acid carbon chain is all longer, and carbon number is generally more than 10, have in addition up to more than 30.Separable pure about kind more than 70 of coming out can be divided into Fatty Alcohol(C12-C14 and C12-C18), sterol and triterpene alcohol three classes from lanolin.Fatty Alcohol(C12-C14 and C12-C18) accounts for the 30-50% of pure total amount, based on branched-chain alcoho.Sterol accounts for about 30% of pure total amount, and wherein cholesterol level is the highest.Triterpene alcohol accounts for the 25-30% of pure total amount.These materials all are in conjunction with forming lanolin with ester bond, can or change esterification method by saponification disconnects ester bond, thereby the acquisition cholesterol, see for details Koresawa T at " Hashimoto R.Journal of SCCJ " the 274th～2788 page of the 29th phase of nineteen ninety-five and Nakajima M. the 84th～95 page of " Fragrance Journal " 1993 the 21st phase.Therefore the general technology route that extracts cholesterol from lanolin is: at first lanolin is carried out saponification or transesterification, make cholesterol dissociate out, adopt suitable separation means that cholesterol is purified then.
Iuchi K, Dezawa K. are open in Japanese Patent JP 76,139,806,1976: the saponification of early stage lanolin is generally carried out in alkali aqueous solution, and the alkali of employing is sodium hydroxide (potassium) or calcium hydroxide.But because the sour and pure carbochain of lanolin is all very long, the solubleness of its saponification resultant in lanolin is bigger, and lanolin is had certain emulsifying effect, and all is insoluble in water, makes that saponification is difficult to thoroughly finish.Thereby the saponification of lanolin is more much more difficult than common grease, need adopt comparatively exacting terms just can finish.Use instead among the Czech patents CS 231912 and in pure alkaline solution, carry out saponification reaction, with lower alcohol (methyl alcohol or ethanol) is solvent, saponification under the effect of sodium hydroxide (potassium), because lanolin has certain solubleness in lower alcohol, make saponification reaction in homogeneous phase, carry out substantially, improved saponification speed and saponification degree.But increased consumption of organic solvent, and emulsion is still quite serious, for follow-up extracting and separating work brings great difficulty.Also having a kind of feasible method is to adopt the thought of transesterificationization, promptly under the effect of strong alkaline substance sodium alkoxide (normally methyl alcohol) lanolin is converted into the lanolin fatty acid low-carbon-ester, makes lanosterol (cholesterol) dissociate out.Compare with saponification method, the transesterification method has following advantage: the one, and the yield height, cholesterol does not go up substantially and loses, and cholesterol has certain loss in the sepn process of method for saponification product; Transesterification process does not in addition make water, and waste water, the waste residue of generation are less; More crucial is that the transesterification product is more easily handled, and lanolin fatty acid methyl esters and cholesterol can be separated by supercritical extraction.
Very complicated through the alcohols material in the lanolin after saponification or the transesterificationization, except that containing cholesterol, also have the materials close such as more beta-cholestanol, lanosterol, agnosterol and lanostenol, make that therefore the mask work of cholesterol is comparatively difficult with cholesterol character.The simplest method is to adopt solvent extration or solvent crystallization, utilizes cholesterol to separate with other sterols material difference of solubleness in organic solvent.As described in Chinese patent CN 1594350, the contriver adopts all kinds of organic solvents that the saponification resultant of lanolin is carried out multi-stage solvent extraction, and recrystallization has finally obtained purity and surpassed 90% cholesterol product then.But it is huge that this operational path solvent expends, and total recovery is extremely low, thereby do not have industrial value substantially.European patent EP 53415 adopts the method for traditional column chromatography that cholesterol is separated with U.S. Pat 4977243, with silica gel is sorbent material, the mixed solution of heptane and acetone is an elutriant, and the yield that obtains cholesterol thus can reach more than 90%, and purity can reach more than 70%.This method gained cholesterol yield is higher, and product can reach more than 90% through purity behind the recrystallization, is a route that industrial prospect is arranged therefore.Patent documentation CZ 237195 and PL164762 have reported that another operational path with industrial value is divalent metal muriate (calcium chloride, magnesium chloride, zinc chloride an etc.) complexometry, utilize the interaction realization of cholesterol and divalent-metal ion uniqueness and separating of other lanosterol, and then the complex compound decomplexing can be obtained cholesterol.But a defective of this method is the metal chloride large usage quantity, and yield is not high, in addition, if adopt zinc chloride also can produce reluctant waste water owing to the introducing of heavy metal ion, causes environmental pollution.The cavity that Japanese Patent JP 07278181 (1995) adopts cyclodextrin separates sterol in the lanolin to the special complex ability of sterols material, but because the price of cyclodextrin own is higher, and the cyclodextrin loss is comparatively serious in the decomplexing process, so this method only is suitable for a small amount of separation of sterols material in the lanolin.
Czech patents CZ 279,996 (1995) adopts molecular distillation technique to extract lanosterol from lanolin.It at first adopts the saponified method with sodium hydroxide lanolin to be hydrolyzed to obtain the trip cholesterol, isolate organic phase with the method for thin film evaporation after with mineral acid saponification resultant being neutralized then, then organic phase is carried out molecular distillation under 200-280 ℃, 0.1-0.01Pa, obtain 72% light constituent at last.This light constituent is handled, promptly obtained lanosterol (mixture of cholesterol and other other lanosterol) behind the acetone extract with CaO.But this patent is not further segmented out cholesterol to lanosterol.
