Storage method
Packed in iron drums or glass bottles. It should be stored in a cool, ventilated warehouse, away from fire and heat sources. Storage temperature-20ºC
Synthesis method
1. Obtained from the esterification of oleic acid and ethanol. Add sulfuric acid to the ethanol solution of oleic acid and heat to reflux for 10 hours. Cool, neutralize with sodium methoxide to pH 8-9, wash with water until neutral, add anhydrous calcium chloride to dry, filter, and obtain ethyl oleate. 2. Tobacco: FC, 18.
Purpose
1. Mainly used as lubricants, water-repellent agents, solvents, oily carriers and synthetic resin tougheners, etc. As a chemical reagent, it is mainly used as a gas chromatography stationary liquid (maximum operating temperature 120°C).
2. Can be used in daily chemical essence and food flavor formulas. Commonly used in baked goods, frozen dairy products, and beverages.
