ABSTRACT:
Tetraphenolic compounds such as the tetraphenol of ethane and the tetraphenol of xylene can be prepared in a heterogeneous reaction mixture using an acidic cationic exchange resin catalyst. A continuous process can be most effectively carried out in the presence of an alcohol cosolvent for the reaction mixture.
