Abstract
PURPOSE: To obtain a lubricating oil additive which exhibits excellent antioxidizing and corrosion-inhibiting action, by a method wherein a sec. alkanolamine is reacted with a reaction product of a polyalkenysuccinic anhydride with a polyalkylene glycol, and the resulting reaction product is reacted with boric acid (or anhydride).
CONSTITUTION: A polyalkenylsuccinic ankydride contg. 740C polyalkenyl group is reacted with a polyalkylene glycol of formula I (wherein R is ethylene, propylene; n is 3W20) or a derivative thereof [derived from an alkylenediamine and ethylene oxide; and all hydrogen atoms of the amine are substituted with polyoxyalkylene or radicals of formula II (wherein n is 3W8)] in a molar ratio of the anhydride to the glycol of 1:(1W0.1) at a temp. of 150W230°C to obtain a first intermediate. One mole of the first intermediate is reacted with 0.3W1.0mol of a sec. alkanolamine at a temp. of 150W200°C. Then one mole (based on polyalkenylsuccinic acid moiety) of the resulting reaction product is reacted with 0.3W1.0mol of boric acid (or anhydride) at a temp. of 100W200°C to synthesize the desired lubricating oil additive.
