Hindered phenyl esters of cyclic borates and lubricants containing same

摘要

New reaction products obtained by reacting (1) a hindered phenol, (2) a boron compound and (3) an amine together are described. Preferred reaction sequences are: (a) (2)+(1), then this product with (3); and (b) (2)+(3), then this product with (1). Also described are lubricant compositions containing the reaction products and a method of reducing fuel consumption in an internal combustion engine by lubricating the engine with a lubricant containing the reaction product.
