The Application of Catalyst in the Alkylation of the Mixture of M-cresol and P-cresol

Aluminum salt of phenol,H2SO4 and acid cation exchange resin are three kinds of common phenolic catalyst.Each catalyst was added to the reaction of isobutene and the mixture of M-cresol and P-cresol(hereinafter referred to as the mixed cresol) to compare the catalytic effectiveness.It shows that when H2SO4 or acid cation exchange resin was added,the conversion of mixed cresol is more than 90% after 2.5hours,while Aluminum salt of phenol could't get 90%.The result indicate that the catalytic activity of H2SO4 and acid cation resin is better than aluminum salt of phenol.
