Synthesis of Phenols You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid‚ by the Dow process‚ and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. Pyrolysis of sodium benzene sulfonate In this process‚ benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt

demanding industrial applications. Polyimides are even used in many everyday applications CLASSIFICATION According to the composition of their main chain‚ polyimides can be: Aliphatic (linear polyimides)‚ Semi-aromatic‚ Aromatic: R ’ and R" are two carbon atoms of an aromatic ring. These are the most used polyimides because of their thermostability. According to the type of interactions between the main chains‚ polyimides can be: Thermoplastic: very often called pseudothermoplastic
