Alkylation of phenol with polybutenes in the presence of benzenesulfonic acid

The purpose of this work is to test benzenesulfonic acid (BSA) as a catalyst in the alkylation of phenol with polyisobutylene (PIB). This material is used as a catalyst in the production of technical C/sub 5/-C/sub 12/ tert-alkylphenol. Finds that the optimal compromise between acceleration of the r...

Zusammenfassung:	The purpose of this work is to test benzenesulfonic acid (BSA) as a catalyst in the alkylation of phenol with polyisobutylene (PIB). This material is used as a catalyst in the production of technical C/sub 5/-C/sub 12/ tert-alkylphenol. Finds that the optimal compromise between acceleration of the reaction and the alkylate viscosity increase that limits the reaction rate is achieved at a temperature of about 105 C and a BSA/PIB mole ratio of 0.15. Recommends BSA as an effective replacement for boron fluoride, boron fluoride complexes, and other highly corrosive catalysts used in the alkylation of phenol with polybutenes.
