Abstract
The invention discloses a wool fat acetylation production process. The wool fat acetylation production process includes the following process steps that 1, a wool fat raw material is put in a reaction still, the interior of the reaction still is vacuumized, and meanwhile heating is carried out so that air and water in the wool fat can be removed; 2, an organic solvent is added into the reaction still; 3, an acetylation agent is added into the reaction still; 4, the interior of the reaction still is heated, and the materials in the reaction still are subjected to an acetylation reaction in the environment of the temperature of 90-110 DEG C; 5, the materials obtained after the reaction in the reaction still in the step 4 are taken out and then distilled, and the finished acetylated wool fat can be obtained. According to the wool fat acetylation production process in the technical scheme, the overall process in the wool fat acetylation production course can be improved, and the quality of the finished acetylated wool fat is improved.
Description
Technical field
The present invention relates to biological and field of medicaments, especially a kind of lanoline acetylation production technology.
Background technology
Lanoline is that main component is sterols, aliphatic alcohols and three by the smegma natural materials out of sheep
The ester that the fatty acid of terpene alcoholss and about equivalent is generated, accounts for 95%, also contains free alcohol 4%, and have a small amount of free fat
Fat acid and hydrocarbons；Lanoline is respectively provided with, in numerous areas such as industrial, medical and daily skin protections, prospect of widely using.Mesh
Before, the preparation process of lanoline is loaded down with trivial details, and its end product quality is unsatisfactory；The acetylation of especially lanoline is processed, existing
Lanoline acetylation often adopts general acetylation in oils industry to process, but reaction conversion ratio is not high, and yield is also paid no attention to
Think, cause hydrogenated lanolin cost of goods manufactured high, economic benefit is inconspicuous.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of lanoline acetylation production technology, and it can be effectively improved acetyl
Change the quality of lanoline finished product.
For solving above-mentioned technical problem, the present invention relates to a kind of lanoline acetylation production technology, it includes following work
Skill step:
1) Pilus Caprae seu Oviss fat raw material is inserted among reactor, evacuation process is carried out to reactor inside, heated up to go simultaneously
Except the air in lanoline and moisture；
2) add organic solvent among reactor, and it is uniform with lanoline raw material stirring；
3) add acetylizing agent among reactor, and reactor materials inside is stirred；
4) process is internally heated so that reactor materials inside is entered under 90 to 110 DEG C of temperature environment for reactor
Row acetylization reaction, the response time is 2 to 4 hours；
5) distilled after the material after the completion of reacting in reactor in step 4) being taken out, you can obtain acetylated lanolin
Product.
As a modification of the present invention, described step 2) in, organic solvent adopt one of toluene and petroleum ether or
Multiple mixing.
As a modification of the present invention, in described step 3), acetylizing agent adopts acetic anhydride.
As a modification of the present invention, in described step 3), the weight portion of acetylizing agent is that in step 1), lanoline is former
The 20 to 40% of material weight portion.
Using the lanoline acetylation production technology of technique scheme, it can be by producing for lanoline acetylation
Integrated artistic in journey is improved, and production operation is easy, and reaction condition is gentle, and reaction conversion ratio and yield significantly improve, raw
Produce manufacturing cost substantially to reduce, the quality of acetylated lanolin finished product is improved simultaneously.
Specific embodiment
With reference to specific embodiment, it is further elucidated with the present invention it should be understood that following specific embodiment is only used for
The bright present invention rather than restriction the scope of the present invention.
