Abstract
1332080 Alkylation of phenols GENERAL ELECTRIC CO 21 July 1971 [22 July 1970 (3)] 34312/71 Heading C2C Phenols having at least one ortho-hydrogen are alkylated by reaction with an alkanol in the presence, as catalyst, of tellurium oxide, tellurous acid, telluric acid, molybdenum oxide, molybdic acid, or a salt of the said acids, at 200‹ to 600‹ C. Preferred catalysts are tellurium dioxide, molybdenum trioxide and ammonium para-molybdate. Molybdenum oxide and salts of molybdic acid may be mixed with magnesium oxide, in which case, the reaction is carried out in the vapour phase and in the presence of water. Catalysts containing magnesium oxide preferably contain 2 to 10% by weight of the molybdenum compound. The preferred alkanol is methanol. Examples describe the alkylation of phenol, cresols, xylenols, trimethylphenols, 2,3, 4,5-tetramethylphenol, 4-phenylphenol, 2-tolylphenol, 2,4-diphenylphenol, 2,3-diphenylphenol, 2-xylylphenol, 2-mesitylphenol, 2-durylphenol, 4-methyl-2-phenylphenol, 2-tolyl-4-phenylphenol, 2-phenyl-4-tolylphenol and 3-methyl-5-phenylphenol.
