ABSTRACT:
Chemically stable p-isopropenyl phenol is produced in the form of a solution by contacting p-isopropenyl phenol, in the form of a gas or a liquid obtained immediately after condensation of said gas, with a polar solvent such as an alcohol, an ester, or an acid amide. The resultant solution of p-isopropenyl phenol can be used as the starting material for subsequent reaction to obtain useful compounds such as hydroquinone. Alternatively, p-isopropenyl phenol may be isolated in crystalline form by adding to the solution a poor solvent for the phenol such as water, or by cooling the solution.
