Description
igi Teile p-Toluolsulfochlorid werden allmählich unter gutem Rühren in eine heiße Lösung von 300 Teilen krist. Schwefelnatrium in 300 Teilen Wasser eingetragen und etwa 1I2 bis ι Stunde auf dem Dampfbad heiß gehalten. Die filtrierte Lösung wird auf o° abgekühlt und abgesaugt. Es resultiert das reine Natronsalz der Sulfinsäure, das durch Mineralsäuren leicht zerlegt werden kann.igi parts of p-toluenesulfochloride are gradually crystallized into a hot solution of 300 parts with thorough stirring. Sodium sulfur added to 300 parts of water and kept hot on the steam bath for about 1 I 2 to 1 hour. The filtered solution is cooled to 0 ° and filtered off with suction. The result is the pure sodium salt of sulfinic acid, which can be easily broken down by mineral acids.
Bei Verwendung von krist. Schwefelnatrium kann das zur Lösung nötige Wasser weggelassen werden.When using Krist. Sulfur sodium can omit the water necessary for the solution will.
191 Teile o-Toluolsulfochlorid werden wie in Beispiel I reduziert, nur bedarf es zur Abscheidung des Natronsalzes der o-Toluolsulfinsäure guter Abkühlung und längeren Stehens.191 parts of o-toluenesulfonyl chloride are like reduced in Example I, only it is necessary to separate the sodium salt of o-toluenesulfinic acid good cooling and prolonged standing.
Beispiel III.Example III.
Ersetzt man das p-Toluolsulfochlorid durch 177 Teile Benzolsulfochlorid, so erhält man bei Anwendung desselben Verfahrens Benzolsulfinsäure. Replacing the p-toluenesulfonyl chloride with 177 parts of benzenesulfonyl chloride is obtained benzenesulfinic acid using the same procedure.
Ebenso erhält man durch Reduktion von 211 Teilen 1 - Chlor - 4 - benzolsulfochlorid mit obigen Mengen Schwefelnatrium die i-Chlor-4-benzolsulfinsäure. Likewise, the reduction of 211 parts of 1-chloro-4-benzenesulphonyl chloride is obtained the above amounts of sodium sulphide i-chloro-4-benzenesulfinic acid.
Aus 219 Teilen φ-Cumolsulfochlorid wird bei Anwendung des gleichen Verfahrens die φ-Cumolsulfinsäure gewonnen.From 219 parts of φ-cumene sulfochloride becomes at Using the same procedure, the φ-cumene sulfinic acid obtained.
Verwendet man wie in Beispiel I 228 Teile a - Naphtalinsulfochlorid, so erhält man die α-Naphtalinsulfinsäure. g0 If, as in Example I, 228 parts of a -naphthalene sulfonyl chloride are used, α-naphthalene sulfinic acid is obtained. g 0
Paten τ-Anspruch:Sponsorship τ claim:
Verfahren zur Darstellung von aromatischen Sulfinsäuren und deren Salzen aus den entsprechenden Sulfochloriden durch Reduktion, dadurch gekennzeichnet, daß man Älkalisulfide in Gegenwart von Wasser als Reduktionsmittel verwendet.Process for the preparation of aromatic sulfinic acids and their salts the corresponding sulfochlorides by reduction, characterized in that alkali metal sulfides are used in the presence of water used as a reducing agent.
