Abstract

Oil soluble resins are prepared by heating in the presence of an alkali catalyst a substantial excess over the equimolecular proportion of formaldehyde with a phenol or phenols having only two of the positions ortho- and parato the phenolic group or groups unoccupied and substituted by at least one aralkyl group, the aliphatic part of which contains at least three carbon atoms and containing at least three aliphatic carbon atoms per phenolic hydroxyl group in the molecule with or without the addition of similar phenols that do not contain the aralkyl group. Suitable phenols include derivatives of diphenyl methane such as p-cumylphenol (dimethylbenzylphenol) which may be derived from o-cresol and aldehydes or ketones or products derived from o-cresol and hydroaromatic ketones such as cyclohexanone or methyl cyclohexanone. In examples: (1) p-cumylphenol is condensed with formaldehyde in the presence of aqueous caustic soda; and (2) methylbutyldicresylolmethane is condensed with formaldehyde in the presence of soda lye. Specifications 334,572, [Class 2 (iii)], and 417,122 are referred to. Methylbutyldicresylolmethane is prepared by condensing o-cresol with methylbutyl ketone in the presence of hydrochloric acid.
