Abstract
This is a preliminary communication on azo couplings in sulphuric acid solution of high concentration. The reaction of the undissociated naphthol which is not measurable in aqueous solution of low acidity (because of the predominant naphtholate coupling) can be demonstrated in sulphuric acid solution of 73–81% H~2~SO~4~.
