Abstract

1,212,472. Polyphenols. AMERICAN CYANAMID CO. 17 Feb., 1969 [19 Feb., 1968], No. 8551/69. Heading C2C. [Also in Divisions C3, C4 and C5] The invention comprises substituted polyphenols of the formula in which A denotes hydroxy, B, R 1 and R 2 denote hydrogen or alkyl groups of 1-8 carbon atoms, R 3 denotes an α-branched alkyl group of at least 3 carbon atoms, R 4 is identical with R 3 or denotes hydrogen or an alkyl group of 1-18 carbon atoms, m is 0 or 1, n is 0-4, p is 2-6, and the sum of m, n and p is 6. The products are obtainable (1) by reacting a hydroxymethyl bezene of the formula with a carboxylic acid of the formula or (2) by reacting the hydroxymethyl benzene with the chloride of such an acid or (3) by reacting a halomethyl benzene of the formula in which X denotes halogen, with a carboxylic acid of the type described in the form of its sodium or potassium salt. Examples are given in which the acid radical is 3,5 - di - tert, - butyl - 4 - hydroxyphenylpropionyl, the hydroxymethyl or halogenomethyl residue is derived from benzene, p-xylene, durene, rnesitylene or p-cresol and p is 2, 3, 4 or 6. The products are useful as antioxidants (see Divisions C3, C4 and C5 ).
