Abstract

1,204,806. Brightening agent. COMPAGNIE DES COMPTEURS. 26 June, 1968 [28 June,- 1967], No. 30576/68. Heading C2C. [Also in Division C7] A process for preparing a brightening agent for cadmium electroplating comprises reacting an aldehyde of the formula RCHO where R is an aryl group containing at least one hydroxy, alkoxy or alkyleneoxy group with thiourea and a compound chosen from thiosemicarbazide and dithiocarbamic acid. In Example I a brightening agent is prepared by treating piperonaldehyde with thiourea at 30‹ C. and then reacting an equimolar quantity of thiosemicarbazide (dissolved in a 1: 1 water-ethanol solvent) with the reaction product at 30‹ C.
