Abstract
A kind of is raw material with fatty oil under the mink skin, makes the method for itself and dehydrated alcohol prepared in reaction mink oil ethyl ester under anhydrous and acidic medium condition.Method and use equipment are simple, and yield height, goods do not have the unhappy smell of fatty oil under the former mink skin and the specific breath of ester class is arranged, and seepage force is strong, can be directly used in medicine and daily skin care product.
Description
The invention belongs to the preparation method of mink oil fatty acid ester.
The preparation method who is used for the mink oil fatty acid ester of medicine, daily skin care product has mink grease hydrolysis method (Czechoslovakia's invention registration publication No. 20 08 76), fractional separation method (Soviet Union's invention and the council of discovery date of declaration 25,10,78.Or in alkaline medium, produce the quaternary halogenide (No. 4012398, United States Patent (USP), patent date 1977,3,5) of mink oil acid amides bulletin № 39).These methods or reaction be (the mink fat hydrolyzing process still has 6% not hydrolysis) not exclusively, perhaps prepare required equipment complexity (fractional separation method) or preparation method's complexity, will synthesize other chemical substances in advance, the method that United States Patent (USP) 4012398 is introduced comes to this.
The objective of the invention is to propose a kind of simple method that just can produce the mink oil ethyl ester with the generalization production unit.
The method that the present invention prepares the mink oil ethyl ester is: at first the mink subcutaneous lipids is drifted out oil with hot water under 90 ° of-100 ℃ of temperature, fatty oil under the mink skin of gained and a certain amount of dehydrated alcohol, join in the reactor of whipping device, under anhydrous and acidic medium condition, temperature is remained between 80 °-100 ℃, normal pressure constantly stirs down, back flow reaction 3 hours.The material proportion following (is mete-wand with fatty oil weight under the mink skin) of various participation reactions:
Fatty oil under the mink skin: 1
Dehydrated alcohol: 0.3-0.5
Anhydrous slufuric acid: 0.03-0.1
The best proportioning of material, dehydrated alcohol and anhydrous slufuric acid are respectively 0.5,0.05.
Adopt the mink oil ethyl ester of the present invention's preparation, the yield height, the unhappy smell of fatty oil under (with fatty oil under the mink skin is mete-wand, can reach 100%-103.7%) no former mink skin and be rich in the distinctive breath of ester class, seepage force increases to 28.5 centimetres from 12.5 centimetres of crude oil.(the seepage force measuring method is as follows: at 25 °-30 ℃ indoor wind sheltering environment, the middling speed filter paper of 35 centimetres of 1 cm x is suspended on the sample to be tested top, filter paper immerses in the sample 1 centimetre, measure the height that sample is gone up filter paper after 24 hours), the mink oil ethyl ester that makes like this can be directly used in medicine and daily skin care product.
Be described further below in conjunction with embodiment.
Now five embodiment are expressed as follows:
Working method is: the material that will participate in reaction requires weighing to mix according to the above ratio, adds reactor, temperature is remained between 80 °-100 ℃ constantly stir back flow reaction 3 hours.
Claims (3)
1, a kind of is raw material with fatty oil under the mink skin, use has the reactor of whipping device, normal pressure prepares the method for mink oil ethyl ester down, it is characterized in that fatty oil and dehydrated alcohol are under anhydrous and acidic medium condition under the mink skin, temperature remains between 80 °-100 ℃, constantly stir back flow reaction 3 hours.
2, the preparation method of mink oil ethyl ester according to claim 1 is characterized in that anhydrous and the acquisition acidic medium condition is to use anhydrous slufuric acid.
3,, it is characterized in that the material proportion that participates in reacting is (is mete-wand with fatty oil weight under the mink skin) according to the preparation method of claim 1 and 2 described mink oil ethyl esters:
Fatty oil under the mink skin: 1
Dehydrated alcohol: 0.3-1
Anhydrous slufuric acid: 0.03-0.1
Best proportioning, fatty oil under the mink skin: 1
Dehydrated alcohol: 0.5
Anhydrous slufuric acid: 0.5
