Abstract
9472. Farbenfabriken vorm. F. Bayer & Co. June 21. 1913, [Convention date]. 1:8-Aminonaphtholsulphonic acid derivatives. -Ureas are prepared by treating with phosgene the compounds obtained by condensing nitrobenzoyl halides or their substituted derivatives with 1:8-aminonaphtholsulphonic acids and subsequent reduction of the nitro group. By repetition of the condensation and reduction processes. acids containing several aminobenzoyl residues may be obtained. and then converted into ureas. The ureas have a. destructive action on blood parasites such as trypanosomes. and also have an affinity for cotton fibre. Azo dyes result by the combination of the above-described ureas with diazobenzene and other diazo compounds.
