Abstract
This invention relates to light-colored manganese carboxylates and to a process for preparing manganese carboxylates. The manganese carboxylate salts are derived from (a) at least one carboxylic acid containing at least about six carbon atoms and characterized by the Formula (I) ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are each independently hydrogen or alkyl groups, and R.sup.4 is an aliphatic hydrocarbylene group or (b) a carboxylic acid mixture comprising at least one carboxylic acid containing at least about six carbon atoms wherein at least about 75% by weight of the carboxylic acids containing at least six carbon atoms in the mixture are characterized by Formula I. Hydrocarbon solutions of such manganese carboxylates are lighter in color and more color stable than hydrocarbon solutions of similar manganese carboxylates wherein the carbon atom alpha to the carboxyl group contains one or two substituents.
