Storage method
Store in a cool and dry place. Storage temperature -20ºC
Synthesis method
1. Obtained from esterification of methanol and oleic acid. Mix oleic acid and methanol, add catalyst concentrated sulfuric acid or p-toluenesulfonic acid, and heat to reflux for 10 hours. Cool, neutralize with sodium methoxide to a pH value of 8-9°C, wash with water until neutral, dry with anhydrous calcium chloride and then distill under reduced pressure to obtain methyl oleate.
Purpose
1. Used as surface-active basic raw material, leather and rubber softener, non-fluorescent mud lubricant for oil exploration, plastic plasticizer, water-repellent agent, toughener of resin, and also used in organic synthesis.
2. Used as an intermediate for detergents, emulsifiers, wetting agents and stabilizers. It is widely used in various emulsified products and also Used as a solvent for fragrances and a lubricant for spray products.
