Abstract

Abstract Vapor phase catalytic methylation with methanol of 2-tert-butylphenol at the temperature 280–300° C proceeds selectively with formation of 6-tert-butyl-2-methylphenol. Elevating reaction temperature above 300° C leads to formation of 2, 6-dimethylphenol. Reaction of 2-tert-butylphenol with methanol in alkaline medium in the presence of zinc oxide is shown to lead initially to formation of a mixture of calixarenes and ...
