Abstract
A method for producing an aromatic compound styrenic compound adduct comprising the steps of: (1) reacting an aromatic compound and a styrenic compound in a first reactor 1 of fixed-bed flow type in a liquid phase in the presence of a solid acid catalyst, (2) circulating a part of the reaction mixture from the above step to the first reactor 1, (3) feeding a reaction mixture flowing out from the first reactor to a second reactor 3, thereby reducing the content of unsaturated components with the aid of a solid acid catalyst, and (4) distilling the resultant reaction mixture, to thereby obtain a fraction having a reduced content of unsaturated components. The method can be used for producing an aromatic compound/styrenic compound adduct having a reduced content of unsaturated components in high yield and at a low cost.
