CAS 79-20-9 Methyl Acetate - Structure
Chemical Formula:C3H6O2, CH3COOCH3
Description: A carboxylate ester resulting from the formal condensation of acetic acid with methanol.
Appearance/Odor: Colorless, transparent liquid with a characteristic fruity or glue-like odor.
Features of Methyl Acetate (MeOAc)
- It can be miscible with most organic solvents;
- It has a wide range of solubility, capable of dissolving acrylic, vinyl, nitrocellulose, epoxy, polyurethane, polyester, phenolic resin, etc.;
- It has a higher flash point and better anti-whiteing performance than acetone, which can better meet the coating and paint process formulas and user requirements;
- In process formulas that require the use of low-boiling-point volatile organic solvents, it can replace ethyl esters and acetone, butyl ketone, etc.;
- In polyurethane shoe materials, it can replace cyclopentane, fluorocarbon, etc., as an environmentally friendly foaming agent.
- Environmentally friendly solvents, with no usage restrictions.
