Abstract

1,181,437. 2,3,5-Trimethyl phenol. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 20 Dec., 1967 [9 Feb., 1967], No. 6269/67. Heading C2C. A process for the preparation of 2,3,5- trimethyl phenol comprises reacting isophorone with a methylating agent, e.g. methanol in the gas phase at a reaction temperature of at least 500‹ C. in the presence of a catalyst comprising either (a) alumina, chromium (III) oxide and, based on chromium (III) oxide, 15 to 40 mole per cent of an alkali metal oxide, preferably potassium oxide or (b) 35% to 45% by weight of chromium (III) oxide and 45% to 60% by weight of copper (I) oxide if desired together with 7% to 15% by weight of barium oxide. A fixed or fluid bed reactor may be used. An example is furnished.
