Abstract
The invention discloses a method for extracting wool grease from sheepskin and wool washing waste water. The method comprises five steps: acidizing, neutralizing, decoloring, washing and filtering, and the organic solvent is not used during the extracting process, so that the method is beneficial to environmental protection, lower in cost and beneficial to industrial expanded operation. The product purity is greater than 99%.
Description
Technical field
The present invention relates to a kind of method extracting lanolin, specifically, relating to a kind of from washing the method extracting lanolin sheepskin wool waste water.
Background technology
Lanolin is the fat secretion thing be attached on wool, is a kind of byproduct reclaimed from waste water from washing wool.Pure lanolin has very strong chemical-resisting and antimicrobial properties, can not become sour rotten, has good perviousness, can infiltrate skin, can as the nutrition agent of pure natural.
The component of lanolin, character and separation: general animal-plant oil is all the compound of glycerine and lipid acid, but not containing glycerine in lanolin, therefore its correct name should be " wool wax ", people are being called lanolin traditionally.Major ingredient is higher fatty acid and high alcohol, and wherein between alcohol and acid, the existing state being combined into fat exists, and also has unbound state to exist.The component of higher fatty acid and high alcohol respectively accounts for 45-55%.From lanolin, isolated acid about has kind more than 30, and wherein straight-chain acid content is less, and branched acids content is more, accounts for 9.5% and about 60% of fatty acid total amount respectively.Also have in addition through base acid, account for 28% of fatty acid total amount.Contained lipid acid, carbonatoms all more than 10, have even up to more than 30, the more, fusing point is higher for carbonatoms.
Lanolin is of many uses, is mainly used in mechanical industry and manufactures senior slushing oil; Medicine industry manufactures rheumatism plaster, zinc oxide adhesive plaster; Chemical fibre industry synthon and synthetic resins; Daily chemical industry manufactures ointment for anti-cracking, cold cream, senior perfumed soap, prevents breach to have special usefulness to protection skin.Due in lanolin containing 20% cholesterol, also can be extracted for medicine industry production hormone.A kind of easy to operate, lanolin extracting method that DNA purity is high of current needs.
Summary of the invention
The object of the invention is to overcome the defect that above-mentioned technology exists, provide a kind of easy to operate, DNA purity high from washing the method extracting lanolin sheepskin wool waste water.
Its concrete technical scheme is:
From washing the method extracting lanolin sheepskin wool waste water, comprise the following steps:
The first step: acidifying: add the H that concentration is 10% ~ 15% in sheepskin hair washing lotion
2sO
4, make the pH of system control 3 ~ 4, keep 60 DEG C of temperature to treat breakdown of emulsion and form floss precipitation, at 60 DEG C, being incubated 30min, staticly settling, removing bottom throw out;
Second step: neutralization: the NaOH with 30% regulates acidity, control pH8.5 ~ 9.0, control temperature 60 DEG C, continues to stir 20min. and leaves standstill 60min, removing bottom impurity;
3rd step: decolouring: add H
2o
2(accounting for total amount 5%), control temperature 60 DEG C, slowly feeds in raw material while stirring, and time controling, at about 60min, all can affect finished product color and luster too soon too slowly, adds rear continuation and stirs 20min, staticly settle 40min, removing bottom impurity.
4th step: washing: adopt water-washing method, be incubated 60 DEG C, leaves standstill 1h, 2 times repeatedly.Discharge washing water and should be neutral.
5th step: filter: lanolin obtains high purity product after filtration afterwards.
Product the key technical indexes meets relevant criterion: its fusing point 36-42 DEG C; Allusion quotation valency 18 ~ 36g/100g; Moisture < 0.5%; Acid value < 0.5mg/g; Saponification value 92 ~ 106mg/g; Ignition residue < 0.15%; Muriate < 0.35%; Solubility readily oxidizable substance is at KMnO
4in not exclusively fade.
Compared with prior art, beneficial effect of the present invention is: present method not with an organic solvent, is conducive to environmental protection; Its operation steps is simple, reduces the cost extracting lanolin.
Accompanying drawing explanation
Fig. 1 is that the present invention is from washing the method flow diagram extracting lanolin sheepskin wool waste water.
Embodiment
Below in conjunction with concrete drawings and Examples, technical scheme of the present invention is described in more detail.
Embodiment:
With reference to Fig. 1, get sheepskin hair washing lotion 5Kg, add the H that concentration is 12%
2sO
4, make the pH of system control 3 ~ 4, keep 60 DEG C of temperature to treat breakdown of emulsion and form floss precipitation, at 60 DEG C, being incubated 30min, staticly settling, removing bottom throw out.NaOH with 30% regulates acidity, makes pH value of solution 8.5 ~ 9.0, and control temperature, at 60 DEG C, continues to stir 20min. and leaves standstill 60min, removing bottom impurity.Add H
2o
2(0.25Kg accounts for total amount 5%), control temperature 60 DEG C, slowly feed in raw material while stirring, time controling is at about 60min.Add rear continuation and stir 20min, staticly settle 40min, removing bottom impurity.Adopt water-washing method, be incubated 60 DEG C, leave standstill 1h, 2 times repeatedly.Discharge washing water and should be neutral.Filter, obtain the high purity lanolin product that weight is about 24.5g.Its fusing point 36 ~ 42 DEG C; Allusion quotation valency 18 ~ 36g/100g; Moisture < 0.5%; Acid value < 0.5mg/g; Saponification value 92 ~ 106mg/g; Ignition residue < 0.15%; Muriate < 0.35%; Solubility readily oxidizable substance is at KMnO
4in not exclusively fade, meet relevant criterion parameter.
The above; be only the present invention's preferably embodiment; protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen within the scope of protection of the present invention.
