4-vinylphenol is a compound that occurs naturally in peanuts, coffee, and wild rice. It appears as a white solid with a medicinal odor. In structure, it has a vinyl double bond, so it is often used in the synthesis of poly4-vinylphenol polymers and resins. Diluted 4-vinylphenol has a sweet smell and is also used in seafood and meat flavoring formulations.
As for the preparation of 4-vinylphenol, it can be carried out in the environment of insufficient oxygen or lack of oxygen. Biomass materials containing lignin and cellulose are used as raw materials for pyrolysis reaction at 200℃~500℃, and the pyrolysis gas is collected, and 4-vinylphenol can be obtained after the condensation of pyrolysis gas.
