Properties and stability

Avoid contact with strong oxidants, strong acids, and strong alkalis. It is non-corrosive to metals when dry. Copper containers should not be used because trace amounts of acetic acid generated by hydrolysis are corrosive to copper. It has the general chemical properties of esters and is easily hydrolyzed in the presence of caustic alkali.

Storage method

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants, acids, and alkalis, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

Refining method: Contains impurities such as free acid and alcohol. During refining, wash with sodium bicarbonate or sodium carbonate aqueous solution, dry with anhydrous sodium carbonate or sodium sulfate and then rectify.

Purpose

Used as a solvent for brushing, nitrocellulose spray paint, baking paint, latex paint, etc. Also used in spice manufacturing.
