  Verfahren zur Darstellung   komplexer, wasserlöslicher Antimonverbindungen   von   Nerkaptokarbonsäuren.   
 EMI1.1 
 
 EMI1.2 
 Beispiel 3.20 Gewichtsteile o-Merkaptobenzoesäure (Thiosalizylsäure) = 
 EMI1.3 
 werden mit Sodalösung neutralisiert. Die so erhaltene neutrale Lösung wird dann mit frisch gefälltem   Antimonhydroxyd ==   Sb   (OH) 3 heiss   gesättigt, filtriert und zur Trockne verdampft. Es hinterbleibt das Natriumantimonsalz der o-Merkaptobenzoesäure als gelbes Pulver, das in Wasser mit schwach alkalischer Reaktion löslich ist. Aus der wässrigen Lösung wird das Antimon durch   Schwefelnatrium   gefällt. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the preparation of complex, water-soluble antimony compounds of nerkaptocarboxylic acids.
 EMI1.1
 
 EMI1.2
 Example 3.20 parts by weight of o-mercaptobenzoic acid (thiosalicylic acid) =
 EMI1.3
 are neutralized with soda solution. The neutral solution thus obtained is then saturated hot with freshly precipitated antimony hydroxide == Sb (OH) 3, filtered and evaporated to dryness. The sodium antimony salt of o-mercaptobenzoic acid remains as a yellow powder, which is soluble in water with a weakly alkaline reaction. The antimony is precipitated from the aqueous solution using sodium sulphide.

PATENT-ANSPRUCH : Verfahren zur Darstellung komplexer, wasserlöslicher Antimonverbindungen von Merkaptokarbonsäuren, dadurch gekennzeichnet, dass man diese Säuren selbst oder ihre neutralen Salze mit Oxydverbindungen des dreiwertigen Antimons behandelt, wobei man in ersterem Falle nachträglich mit Alkalien oder Erdalkalien neutralisiert. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the preparation of complex, water-soluble antimony compounds of mercaptocarboxylic acids, characterized in that these acids themselves or their neutral salts are treated with oxide compounds of trivalent antimony, in the former case being subsequently neutralized with alkalis or alkaline earths. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
