What is 4 vinylphenol?

1. Chemical structure: 4-vinylphenol is an organic compound belonging to the phenol family. It has a vinyl group (-CH=CH2) attached to the 4-position of the phenolic ring. Its chemical formula is C8H8O.

2. Physical properties: 4-vinylphenol is a colorless to yellowish liquid with a phenolic odor. It has a boiling point of 221-223°C and a melting point of -13°C. It is soluble in organic solvents like ethanol, acetone, and benzene but insoluble in water.

3. Synthesis: 4-vinylphenol can be prepared by the reaction of phenol with acetylene in the presence of a palladium-copper catalyst. It can also be obtained by the deprotection of 4-vinylphenol acetate or by the isomerization of 2-vinylphenol.

4. Uses: 4-vinylphenol is used as a monomer for the production of various polymers and resins. It is also used in the synthesis of other specialty chemicals like 4-vinylphenol polymer-bound palladium catalysts, 4-vinylphenol-maleic anhydride copolymers, and 4-vinylphenol-epoxy resins. It is a useful intermediate in the manufacture of pharmaceuticals, agrochemicals, and fragrances.
