ABSTRACT:
Substantially improved yields of 2,4,6-trialkylphenols result from alkylating a mixture of phenol and 2,6-dialkylphenol, the latter being a by-product of the alkylation reaction. This results flows from an unexpected synergistic effect accompanying transalkylation. The continuous method of making 2,4,6-trialkylphenol based on this property affords the highly desirable trialkylated phenols in high yield.
