Lanolin Anahydrous CAS# 8006-54-0

It is mainly used in the manufacture of advanced anti-oil for machinery industry, rheumatism cream and zinc oxide rubber paste for the pharmaceutical industry, synthetic fiber and synthetic resin for chemical fiber industry, anti-cracking cream for the daily chemical industry, synthetic fiber and synthetic resin for chemical fiber industry, anti-cracking cream, cold cream and advanced soap for the daily chemical industry. Lanolin contains 20% cholesterol, which can be extracted and used for the production of hormones in the pharmaceutical industry. Lanolin is a long-established raw material, and this renewable resource has many potential values. Its use in medicine and cosmetics is quite extensive.

Preparation method:

An inert gas with water synthesis of refined lanolin method, the crude lanolin hydrolysis products – linoleic acid and lanolin alcohol as raw materials, the following steps in order:

1. take 50g each of linoleic acid and lanolin alcohol, potassium hydroxide 0.2g in a 250ml single mouth bottle, the system continuously pass N2, pass rate 1ml / (ml-s), 190 ~ 200 ℃ under the conditions of the reaction for 9h, after cooling to room temperature The lanolin paste solid (lanolin solid product) was obtained; i.e., the amount of N2 passed into this 250ml single-mouth bottle per second was 250ml for the 250ml single-mouth bottle as a reaction vessel.
2. Add 25g of sodium chlorite and 50ml of methanol to the lanolin paste solid obtained in step 2), add 5g of 37% hydrochloric acid slowly dropwise (controlling the temperature ≤ 70°C during the dropwise addition), and decolorize the product at 70°C for 2h; 3. Add 50ml of hot water (water at 50-55°C) to the decolorized product obtained in step 2) while it is still hot and wash it, take the upper oil phase in the split-phase, and repeat the washing three times (washing conditions as above), cooled to room temperature to obtain a light yellow solid product, vacuum (vacuum 0.096Mpa) drying (drying at 70 ℃ to constant weight), resulting in lanolin 96.1g, yield 96.1%, acid value of 0.89.
