Synthesis method
1. Mix ethyl oleate and anhydrous acetic acid, quickly add metal sodium flakes, and the reaction proceeds vigorously. After the reaction eases, add absolute ethanol and heat until the sodium metal completes the reaction. Then add water and reflux for 1 hour to saponify unreacted ethyl oleate. cool downAfter that, it is extracted with ether, neutralized and washed; after drying, the ether is evaporated, and fractionation is carried out under reduced pressure to collect the 150-152°C (0.133kPa) fraction, which is oleyl alcohol. The yield is about 50%.
Purpose
1. Used in the manufacture of detergents; wetting agents; defoaming agents; lubricants for metal cutting; plasticizers and fabric softeners.
2. Used in organic synthesis , raw materials for special surfactants, which can be used to produce oil additives, cold-resistant auxiliary plasticizers, lubricants and solvents, etc.
3. Fat-enriching agent is a raw material for the production of wetting agents, emulsifiers, detergents, and dispersants. It is also suitable for use in cosmetics and medicines. The oily component of the preparation.
