ABSTRACT:
This invention relates to processes for making nitro compounds derived from C2-C30unsaturated fatty acids; C2-C30unsaturated fatty oils; esters derived from the reaction of C1-C20alcohols with unsaturated C2-C30fatty acids; C2-C20polyolefins; C4-C20polydiolefins; C8-C20copolymers derived from polyolefins and vinyl aromatics; and C4-C30alkylated phenols using nitric acid or gaseous nitrogen dioxide. This class of extreme-pressure additives was found extremely effective in processing steel, stainless steel and special titanium and nickel or low-iron alloys.
