Abstract
A method for the purification of 4-methyl-2,6-di-tert.butylphenol prepared by orthoalkylation of phenol with subsequent aminomethylation and hydrogenolysis of m, N-dimethyl-3,5-ditert.butyl-4-hydroxybenzylamine by crystallization in methanol, characterized in that the crystallization is conducted at a temperature comprised within the range of 0 to 45ºC in methanol containing 3 to 10% in but of water in a weight ratio of 4-methyl-2,6- di-tert.butylphenol to said aqueous methanol solution from 1: 1 to 1: 4.
