Abstract
Oxyamine bases in monomeric form or of low molecular weight containing active methylene groups are prepared by condensing hydroxyaryl compounds or ethers thereof which contain more than one active methylene group with aromatic amines, the condensation being interrupted preferably as soon as the product shows a diminution of solubility in alcohol and in any case as soon the product shows a diminution in solubility in acetone. The products may be freed from impurities by treatment with inert gases or vapours such as steam preferably under reduced pressure. Suitable starting materials include methylol or chloromethyl derivatives of hydroxy-aryl compounds which may or may not contain alkyl or aryl substituent groups such as phenol, cresols, oxidiphenyls, iso-propyldioxydiphenyl or their alkyl, oxyalkyl or polyoxyalkylethers and amines such as aniline alkylanilines, aminobenzylaniline, diaminodiphenylmethane and benzidine. In examples: (1) a solution of crude cresol in caustic soda is treated with formaldehyde and the product is treated with aniline monoethylaniline or dimethylaniline in the presence of hydrochloric acid; (2) an aqueous alkaline solution of polymethylol is treated with aniline; (5) polychloromethylenecresol (obtained by treating crude cresol with a mixture of formaldehyde and hydrochloric acid) is treated with aniline in the presence of sodium bicarbonate; (6) p-oxydiphenyl is dissolved in caustic soda, treated with formaldehyde and the product is treated with aniline in the presence of acetic acid; (7) the polymethylolcresol prepared according to claim 1 is etherified with dimethyl sulphate, treated with aniline in the presence of hydrochloric acid and further treated with formaldehyde; (8) iso-propyldiphenol is treated with formaldehyde in the presence of caustic soda and the product is condensed with benzidine in the presence of acetic acid; (9) the polymethylolcresols made according to example 1 are condensed with aminobenzylaniline in the presence of acetic acid.
