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.
在水或烷氧基化胺或二氢羰基膦酸盐或二氢羰基膦酸盐(或这类物质的混合物)存在的情况下,加热长链琥珀酰亚胺和苯并三唑的混合物,然后蒸馏所得产物中的挥发性成分,就可以形成一种适合用作润滑油添加剂的均质浓缩物。如果在加热过程中再加入硼酸等硼化剂,并通过蒸馏去除挥发性成分,则不仅可以形成兼容的浓缩添加剂,而且长链琥珀酰亚胺也会在此过程中被硼化。
