ABSTRACT:
A homogeneous concentrate suitable for use as an additive for lubricating oils is formed from a long chain succinimide and a benzotriazole by heating a mixture of these materials in the presence of water or alkoxylated amines or dihydrocarbylphosphites or dihydrocarbyl phosphonates (or mixtures of such materials) and then distilling the volatile component, from the resulting product. When this heating step is conducted in the additional presence of a boronating agent such as boric acid and the volatile component, is removed by distillation, not only is a compatible additive concentrate formed, but the long chain succinimide is boronated in the process.
