4-vinylphenol, also known as p-vinylphenol, is a white solid compound with a phenol-like chemical and medicinal flavor, as well as a musty and meaty aroma. When diluted, it tastes sweet and can be used in seafood and meat flavor formulations. It is found naturally in tomatoes, corn, mangoes, apples, strawberries, black tea, mushrooms, coffee, wild rice and other foods. In the molecular structure of 4-vinylphenol, the existence of vinyl double bond is conducive to the synthesis of 4-vinylphenol polymer and resin.
The preparation process of 4-vinylphenol seems to be relatively simple. It needs to be prepared in anoxic or anaerobic environment. Biomass materials rich in lignin and cellulose are used as raw materials for pyrolysis reaction at 200 ℃ ~ 500 ℃, and the pyrolysis gas is collected and condensed to obtain 4-vinylphenol.
