Procedure

The condensate was dissolved in 400 ml of water and a solution of 21.9 g (0.0600 mole ) of sodium n-dodecylbenzene-sulfonate in 600 ml of water was added to the solution with vigorous stirring. The resulting yellow precipitates were filtered off and dried to give 22 g of a dodecylbenzenesulfonate of the condensate of phenoxyacetic acid·4-diazodiphenylamine and formaldehyde.
