Abstract

1,229,574. Phenols. IMPERIAL CHEMICAL INDUSTRIES Ltd. 17 June, 1968 [28 June, 1967], No. 29882/67. Heading C2C. [Also in Division C3] The invention comprises phenols of formula wherein R represents an optionally substituted alkyl, cycloalkyl, aralkyl, aryl or acyl group; each R<SP>1</SP> which may be the same or different, represents a hydrogen atom or an alkyl group; and each R<SP>11</SP> and R<SP>111</SP>, which may be the same or different, represents an alkyl or cycloalkyl group. These phenols may be prepared by reacting a compound of formula with two molar proportions of a hydroxymethylphenol or derivative of formula wherein R<SP>11</SP> and R<SP>111</SP> have the significances given earlier and A represents a hydrogen atom or an alkyl or acyl group containing up to 4 carbon atoms. 3,5 - Bis - (3,5 - di - t.butyl - 4- hydroxybenzyl) - 2,4,6 - trimethyl anisole is prepared in the example.
