Vinyl acetate
Physical and Safety Properties: This clear, highly flammable liquid demonstrates miscibility with ethanol and dissolution capability in organic solvents including ether, acetone, and chloroform.
Organoleptic Properties: The substance emits a characteristically sweet, fruity aroma suitable for applications requiring fragrance components.
Reactive Characteristics: The compound participates in reactions with acidic, alkaline, and oxidizing substances, supporting its utilization in polymerization systems and synthetic chemistry.
Polymerization Behavior: Displaying sensitivity to light exposure, the material typically requires stabilization with inhibitors such as hydroquinone to moderate polymerization tendencies 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.
