ABSTRACT:
A method for producing alkylstyrene which is characterized in that 1,2-di(substituted phenyl)ethane is brought into contact with an acid catalyst at 200.degree. C. to 650.degree. C. in the presence of an inert gas to crack it into alkylstyrene and alkylbenzene. The method of the invention has advantages in that the operation of reaction and separation of reaction mixture are quite easy, the lowering of catalytic activity is small, and unreacted starting material can be reused.
