Abstract: Vapor phase catalytic methylation with methanol of 2-tert-butylphenol at the temperature 280-300A degrees C proceeds selectively with formation of 6-tert-butyl-2-methylphenol. Elevating reaction temperature above 300A degrees 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 methylenebisphenols that at elevated temperature exert splitting leading in future to 6-tert-butyl-2,4-dimethylphenol. Obtaining it in this reaction from 2,2'-methylenebis-(6-tert-butyl-4-methylphenol) proceeds selectively. Pathways of the reductive methylation of methylenebisphenols with methanol in alkaline medium is considered.
