Abstract

A resinous product is prepared by the condensation of an aldehyde or ketone with a phenol in an acidic medium in the presence of a mercapto-substituted aliphatic carboxylic acid or a mercaptol or mercaptal thereof. The mercapto acids specified include mercaptoacetic and thiolactic acids, and particularly b -mercaptopropionic acids. Phenols mentioned include cresols, phenol, chlorophenols and nitrophenols; carbonyl compounds specified include formaldehyde, acetone, methylethylketone, cyclohexanone, benzaldehyde, acetophenone, acetonylacetone and acetaldehyde. In an example (10), phenol is treated with formaldehyde under the above conditions to give a resinous product.ALSO:A phenolic condensation product is prepared by condensing a phenol with an aldehyde or ketone in an acidic medium in the presence of a mercapto-substituted aliphatic carboxylic acid or mercaptol or mercaptal thereof. Mercapto acids specified are mercaptoacetic acid, thiolactic acid, a -, b - and g -mercaptobutyric acids, a : b - dimercaptobutyric acid, mercapto-substituted myristic, oleic, adipic, succinic and aconitic acids, and particularly b -mercapto-propronic acid; salts, esters, or other hydrolysable derivatives may also be used. The acidic medium may be produced by any acid substance, e.g. hydrogen chloride, with or without calcium chloride; excess phenol, e.g. 4-8 mols., is preferably used. The percentage of mercapto-acid may be as high as 10 per cent, but is preferably 0.01 to 0.5 mols. An inert solvent may be used. Increased pressure may be employed at a temperature, e.g. of 20-50 DEG C. Phenols mentioned include cresols, a - and b -naphthol, o-chlorophenol and other halogenated phenols, and nitrophenols. Ketones mentioned include methyl ethyl ketone, mesityl oxide, acetonylacetone, acetophenone, cyclohexanone, and aldehydes are represented, for examples, by acetaldehyde and benzaldehyde. Ketones are the preferred reactants. In the examples, (1-7) 2 : 2-bis-(41-hydroxyphenyl) - propane is prepared from phenol and acetone in acidic solution in the presence of mercapto-acetic and propionic acids, their salts and esters, and of acetone di-(b -carboxyethyl) - mercaptol; (8) o - cresol is used in place of phenol; (9) methyl ethyl ketone is used in place of acetone, and (10) phenol is treated with formaldehyde to give bis-p-hydroxyphenylmethane.
