A process for making a product containing tin (II) carboxylates of the formula (RCOO)2-n(OOCR')n, where each R, which may be the same or different, is hydrogen or a C1-C40 hydrocarbyl group, each R', which may be the same or different, is a C1-C40 hydrocarbyl group, and n is 0, 1, or 2 the process comprising:(a) forming a reaction mixture by combining elemental tin, a promoter, and one or more carboxylate-containing compounds of the formula R(CO)X, where R is hydrogen or a C1-C40 hydrocarbyl group and X is a hydroxyl group, a halogen atom, or O(CO)R', where R' is a C1-C40 hydrocarbyl group;(b) heating the reaction mixture to form heated reaction mixture;(c) oxidizing the heated reaction mixture using an oxygen-containing gas to form an oxidized reaction mixture containing tin (II) carboxylates as well as tin (IV) carboxylates; and(d) reducing the oxidized reaction mixture with elemental tin to convert at least a portion of the tin (IV) carboxylates to tin (II) carboxylates to form the product containing tin (II) carboxylates.
