Abstract
Compounds of the formulae 1a and 1b are prepared by desulfonation of the corresponding disulphonic acid. It is also possible to start from the compounds free from sulphonic acids, to sulphonate these and to desulphonate the disulphonic acid compounds. The splitting-off of the sulphonic acid group takes place in aqueous 1 to 90% strength mineral acid at 80 to 140 DEG C. The compounds of the formulae 1a and 1b can be used to prepare azo components. <IMAGE>
