Vinyl alcohol is a colorless, flammable liquid with the chemical formula C₂H₄O. It is an unstable compound that can exist in equilibrium with its tautomer, acetaldehyde. Vinyl alcohol is primarily used in the production of polymers and resins, particularly in the synthesis of polyvinyl alcohol, which is a versatile material used in various applications, including adhesives and coatings. Due to its instability, vinyl alcohol is not commonly found in nature and is typically produced in laboratory settings. Its properties make it an important intermediate in organic chemistry, contributing to the development of other chemical compounds and materials, including those used in the textile and packaging industries.
