In der Patentschrift Nr. 79028 ist angegeben, dafs ο - Toluylsä'ure erhalten wird, wenn man Naphtalin-m-disulfosäure oder die sich von dieser durch Ersatz einer Sulfogruppe durch OH bezw. NH2 ableitenden Naphtol- bezw. Naphtylamin - m - sulfosäuren mit Aetzalkalien auf höhere Temperatur erhitzt. Wenn dagegen die von der Naphtylamin-m-disulfosäure sich ableitenden Trisulfosäuren, welche die weitere Sulfogruppe im noch nicht substituirten Benzolring enthalten, mit Alkalien in geeigneter Weise verschmolzen werden, so entsteht je nach der Stellung der dritten Sulfogruppe o- bezw. p-Oxy-o-toluylsäure oder m-Kresol, letzteres offenbar als Spaltungsproduct der in der Natron-Patent specification No. 79028 states that ο - toluic acid is obtained if naphthalene-m-disulfonic acid or which is different from this by replacing a sulfo group with OH or. NH 2 derived naphthol respectively. Naphthylamine - m - sulfonic acids heated to a higher temperature with caustic alkalis. If, on the other hand, the trisulfonic acids derived from the naphthylamine-m-disulfonic acid and which contain the further sulfo group in the not yet substituted benzene ring, are fused with alkalis in a suitable manner, depending on the position of the third sulfo group, o- or. p-Oxy-o-toluic acid or m-cresol, the latter apparently as a cleavage product of the

Die vorstehend erwähnten Reactionen verlaufen bei vorsichtig geleiteten Operationen durchaus quantitativ. Wird dagegen der Procefs beschleunigt, so entsteht besonders leicht aus den Naphtalintrisulfosäuren und aus den von den Naphtol- und Naphtylamin-m-sulfosäuren sich ableitenden Disulfosä'uren o-Toluylsäure. The above-mentioned reactions proceed with carefully directed operations quite quantitative. If, on the other hand, the process is accelerated, it arises particularly easily from the naphthalene trisulphonic acids and from the naphthol- and naphtylamine-m-sulphonic acids derived disulfonic acids o-toluic acid.
60 kg Naphtalin Γαχ ß2 a3-trisulfosäure, erhalten durch Behandeln von Naphtalin-A1 a3-disulfosäure mit starker rauchender Schwefelsäure bei niederer Temperatur, werden mit 120 kg Aetznatron und 90 1 Wasser in einem Autoclaven 15 Stunden auf 2500 erhitzt. Die Schmelze wird in Wasser gegossen," die Lösung angesäuert, bis zur Entfernung der schwefligen Säure gekocht und filtrirt. Beim Erkalten krystallisirt die o-Oxy-ο -toluylsäure aus. Der Schmelzpunkt liegt, entgegen den Angaben Jacobsens, bei 141,5 bis 1420.60 kg naphthalene Γ α χ ß 2 a 3 -trisulfosäure, obtained by treating naphthalene-A 1 a 3 -disulfosäure with strong fuming sulfuric acid at low temperature, with 120 kg of caustic soda and 90 1 water in an autoclave 15 hours at 250 0 heated. The melt is poured into water, the solution acidified, boiled until the sulphurous acid is removed and filtered. On cooling, the o-oxy-o-toluic acid crystallizes out. Contrary to Jacobsen's statements, the melting point is 141.5 to 142 0 .
