Disclosed is a process for preparing a molybdated succinimide complex, the process comprising: (a) reacting an alkyl or alkenyl mono- or bis-succinimide of a polyamine of formula I or formula II or mixtures thereof: Formula (I), Formula (II) with an α,β-unsaturated mono-carboxylic acid or carboxylic acid ester, and wherein the reaction temperature is in the range of from greater than 80°C to no greater than about 150°C; and (b) reacting the succinimide product of step (a) with an acidic molybdenum compound to provide the molybdated succinimide complex, wherein the molybdated succinimide complex is a liquid at room temperature. |
