Description
Verfahren zur Herstellung einer neuen Arsenverbindung. Es wurde gefunden, dass analog der Acetophenonarsinsäure auch die Oxyace- tophenonarsinsäure durch Reduktionsmittel, welche nur die Arsinsäuregruppe angreifen, in die entsprechende Arsenoverbindung über führbar ist.
Als Reduktionsmittel kommen auch hier in Betracht Natriumhydrosulfit, Phosphortrichlorid, phosphorige Säure, unter- phosphorige Säure, Zinnchlorür plus Jod- wasserstoffsäure etc.
Das Arsenooxyacetophenon ist ein gel ber, in Natronlauge löslicher Körper, 'dem folgende Formel zukommt
EMI0001.0016
<I>Beispiel:</I> 2,6 g Oxyacetophenonarsinsäure wird mit Normal-Natronlauge in Lösung gebracht und diese Lösung versetzt mit einer Lösung von 25g Natriumhydrosulfit und 5 g Magnesium chlorid in 100 ccm Wasser. Die beiden Lö sungen werden vereinigt und das Gemisch dann unter Luftabschluss bei kräftigem Rüh ren 1'2-2 Stunden auf<B>600</B> C erwärmt.
Nach Ablauf dieser Zeit wird das ausge schiedene, leicht filtrierbare, gelbe Arseno- oxyacetophenon unter Luftabschluss abfiltriert und im Vakuum getrocknet.
Process for the preparation of a new arsenic compound. It has been found that, analogously to acetophenonarsinic acid, oxyacetophenonarsinic acid can also be converted into the corresponding arsenic compound by reducing agents which only attack the arsinic acid group.
Sodium hydrosulfite, phosphorus trichloride, phosphorous acid, hypophosphorous acid, tin chloride plus hydriodic acid, etc.
Arsenooxyacetophenone is a yellow body which is soluble in sodium hydroxide solution and has the following formula
EMI0001.0016
<I> Example: </I> 2.6 g of oxyacetophenonarsinic acid is brought into solution with normal sodium hydroxide solution and this solution is mixed with a solution of 25 g of sodium hydrosulfite and 5 g of magnesium chloride in 100 cc of water. The two solutions are combined and the mixture is then heated to <B> 600 </B> C for 1'2-2 hours with vigorous stirring in the absence of air.
After this time, the separated, easily filterable, yellow arseno-oxyacetophenone is filtered off in the absence of air and dried in vacuo.
