Description
Verfahren zur Herstellung eines Ogyarylsnlfons. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines Oxyary1sul- fons, @dadurch gekennzeichnet, dass man 2,5-Diehlordiphenylsulfon mit einem alka lisch wirkenden Mittel erhitzt.
Das so erhaltene 5-Chlor-2-oxydiphenyl- sulfon ist ein farbloser Körper vom Sehmelz- punkt 13'8-139 C. Es soll als Zwischenpro dukt zur Herstellung von Farbstoffen, Heil- mitteln, Textil- und Gerbereihilfsmitteln so wie von synthetischen Harzen Verwendung finden.
<I>Beispiel:</I> 230 Teile Kaliumhydroxyd werden mit etwa 50 Teilen Wasser und 700 Teilen Me thylalkohol in der Wärme gelöst. In die Lö sung werden 287 Teile 2,5-Dichlordiphenyl- sulfon vom Fp. 154-155 C, erhältlich bei spielsweise durch Kondensation von 2,5-Di- chlorbenzol@sulfochloxid mit Benzol, eingetra gen.
Man erhitzt die Mischung etwa 3 Stun den im Rührautoklaven auf 155-1ö0 C, lässt erkalten, saugt die entstandene klare Lö sung des Schmelzproduktes von dem aus- geschiedenen Chlorkali ab und trägt sie unter Rühren auf in Überschuss vorgelegte verdünnte Salzsäure aus. In fast theore tischer Ausbeute fällt das 5-Chlor-2-oxydi- phenylsulfon aus, das abgesaugt, mit Wasser auf der Nutsche gewaschen und getrocknet, ein weisses Pulver .darstellt, welches, aus Chlorbenzol umgelöst, den Schmelzpunkt <B>13,8-1-3,9'</B> C zeigt.
Method of making an ogyaryl phone The present patent relates to a process for the production of an oxyaryl sulfone, characterized in that 2,5-diehlordiphenyl sulfone is heated with an alkali agent.
The 5-chloro-2-oxydiphenylsulfone obtained in this way is a colorless body with a melting point of 13.8-139 C. It is intended as an intermediate product for the manufacture of dyes, medicinal products, textile and tanning aids, as well as synthetic resins Find use.
<I> Example: </I> 230 parts of potassium hydroxide are dissolved in the heat with about 50 parts of water and 700 parts of methyl alcohol. 287 parts of 2,5-dichlorodiphenylsulfone with a melting point of 154-155 ° C., obtainable for example by condensation of 2,5-dichlorobenzene sulfochloxide with benzene, are entered into the solution.
The mixture is heated to 155-10 ° C. in a stirred autoclave for about 3 hours, allowed to cool, the resulting clear solution of the melt product is suctioned off from the precipitated potassium chloride and discharged onto dilute hydrochloric acid, which has been introduced in excess, with stirring. The 5-chloro-2-oxydiphenylsulfone precipitates in almost theoretical yield, which is filtered off with suction, washed with water on the suction filter and dried, a white powder which, when redissolved from chlorobenzene, has a melting point of 13.8 Shows -1-3.9 'C.
