Abstract
326,022. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). March 12, 1929. Sulphonic acids of 1-#-amiomethylnaphthalene are obtained by sulphonating 1-w-aminomethylnaphthalene with such agents as concentrated or fuming sulphuric acid. A mixture of the 2- and 4-sulphonic acids is obtained, and they may be further sulphonated to the 2 :4-disulphonic acid, with or without previous separation. In examples, (1) anhydrous sulphuric acid reacts on 1-#-aminomethylnaphthalene to give a mixture of the internal salt of 1-w-aminomethylnaphthalene- 2-sulphonic acid, and 1-#-aminomethylnaphthalene-4-sulphonic acid; (2) the mixture of monosulphonic acids is further sulphonated to the 2 : 4- disulphonic acid with fuming sulphuric acid; (3) the 2 : 4-disulphonic acid is obtained from the 1-#-aminomethylnaphthalene - 2 - sulphonic acid with anhydrous, then fuming sulphuric acid; (4) the 2 : 4-disulphonic acid is obtained by the action of anhydrous, then fuming, sulphuric acid, on sodium 1-#-aminomethylnaphthalene-4-sulphonic acid. The corresponding naphthaldehyde sulphonic acids may be obtained from these products.
