A light colored basic alkali or alkaline earth metal organic salt is obtained by the reaction of a basic metal compound, an alkyl phenol and/or a carboxylic acid, carbon dioxide, and thereafter post-treating the reaction product with an organic phosphite. Alkaline earth metal salts of phenols and carboxylic acids include barium or calcium. Organic phosphites include trialkyl or dialkyl phosphites such as triisodecyl phosphite or diisooctyl phosphite.

Sel organique d'un métal alcalino-terreux ou alcalin basique à couleur vive obtenue par réaction d'un composé métallique basique, d'un alkylphénol et/ou d'un acide carboxylique, de dioxyde de carbone, puis par traitement consécutif du produit de réaction par un phosphite organique. Les sels métalliques alcalino-terreux de phénols et d'acides carboxyliques incluent le baryum ou le calcium. Les phosphites organiques incluent les phosphites trialkyle ou dialkyle tels que le phosphite tri-isodécyle ou le phosphite di-isooctyle.
