Vinyl acetate CAS：108-05-4
Physical and Safety Features：This transparent and highly flammable liquid can mix evenly with ethanol and dissolve in organic solvents such as ether, acetone and chloroform.
Sensory Characteristics：It has a distinct sweet and fruity odor, making it suitable for products that need fragrance ingredients. Chemical Reactivity：It can react with acids, alkalis and oxidizing agents, so it is often used in polymerization reactions and organic synthesis.
Polymerization Tendency：The substance is sensitive to light and usually needs stabilizers like hydroquinone to slow down its polymerization during storage.
A transparent flammable liquid possessing a characteristic ethereal aroma. It demonstrates high miscibility with ethanol and solubility in multiple organic media including diethyl ether, acetone, chloroform, and carbon tetrachloride, while remaining immiscible with aqueous systems.
