Title: (DE) Verfahren zur Herstellung von Goldcarboxylaten.
(EN) Process for preparing gold carboxylates.
(FR) Procédé pour la préparation de carboxylates d'or.
Abstract:
(EN) Gold carboxylates and a process for preparing gold salts of organic carboxylic acids are described. The gold carboxylates are represented by formula (I), in which R represents hydrogen or an organic group of valence y and x, y and z each represent a positive integer such that x = y.z/3. The process comprises reacting an alkali or alkaline earth metal salt of an organic carboxylic acid with a gold salt in an organic liquid which at least partially dissolves the alkali and/or alkaline earth metal salt, the gold salt, and the desired gold carboxylate product, but is not a solvent for the salt formed between the alkali or alkaline earth metal and the anion of the gold salt.
(FR) L'invention décrit des carboxylates d'or, ainsi qu'un procédé servant à préparer des sels d'or d'acides carboxyliques organiques. Les carboxylates d'or sont représentés par la formule (I), dans laquelle R représente hydrogène ou un groupe organique à valence y et x, y et z représentent chacun un entier positif tel que x = y.z/3. Le procédé comprend la réaction d'un sel de métal alcalin ou alcalino-terreux d'un acide carboxylique organique avec un sel d'or, dans un liquide organique qui dissout, au moins partiellement, le sel de métal alcalin et/ou alcalino-terreux, le sel d'or, ainsi que le carboxylate d'or souhaité, mais ne dissout pas le sel formé entre le métal alcalin ou alcalino-terreux et l'anion du sel d'or.
