Patent
·
OSTI ID:6353387
A railway diesel crankcase lubricant composition is described comprising a diesel lubricating oil and from about 0.25 to 2.0 weight percent of minor amount of oxidation and corrosion inhibiting agent. The reaction product is of a polyoxyisopropylene diamine, diabasic acid anhydride and polyalkylene polyamine wherein: (i) reacting a dibasic acid anhydride with a polyoxyisopropylenediamine where x is a numeral of about 2 to about 50, forming a maleamic acid; (ii) reacting the maleamic acid with a polyalkylene polyamine, forming a condensate product and; (iii) recovering the condensate product.
