| abstract | O1 - Sulphobenzal - p - diethylaminoaniline is prepared by adding an aqueous solution of sodium benzaldehyde - o - sulphonate to an aqueous solution of p - aminodiethylaniline hydrochloride. O1 - Sulphobenzal - p - hydroxyaniline and o1 - carboxybenzal - p - hydroxy aniline are similarly prepared and similar anils can be prepared from other amines, e.g. o - aminophenol, 4 - hydroxy - m - toluidine, 2 : 6 - di - iodo - 4 - aminophenol, 2 - amino-4 - sulphophenol, 3 - sulpho - 4 - aminophenol, 3 - chloro - 4 - aminophenol, 3 : 4 - diaminophenol, N : N-dimethyl-, N-methyl-, N : N-bis-b -hydroxyethyl-, N-octadecyl-, N : N-dibutyl-, N : N-diethyl-3-ethyl-, and N : N-diethyl - 2 - methyl - p - phenylenediamine, aminotetrahydroquinoline, and p-aminophenylmorpholine, and from other aldehydes, e.g. m- and p-sulphobenzaldehyde, glyoxylic acid, 3-chlorophthalaldehydic acid, and the half aldehyde of adipic acid, and their Na or K salts, or from ketones containing an acid group such as laevulinic acid and a -ketopimelic acid. |
