@ A process for preparing transition metal salt compositions of organic carboxylic acids having improved properties wherein the transition metal is one capable of having a multiplicity of oxidation states is described. The process comprises the steps of (a) providing at least one transition metal compound wherein the transition metal is at one of its higher positive oxidation states, (b) treating said transition metal compound with at least one reducing agent forming an intermediate containing the transition metal in a lower positive oxidation state, (c) reacting said intermediate with at least one organic carboxylic acid to form the transition metal salt of said carboxylic acid, and (d) mixing said transition metal salt formed in step (c) with (i) at least one antioxidant, or (ii) at least one additional metal salt wherein the additional metal is more electronegative than the transition metal, or (iii) mixtures of (i) and (ii). The transition metal salt compositions prepared in accordance with the process of the invention are useful in a variety of applications including resins, inks, paints, lubricants and fuels. |
