Abstract
This invention relates to processes for making nitro compounds derived from C-Cunsaturated fatty acids; C-Cunsaturated fatty oils; esters derived from the reaction of C-Calcohols with unsaturated C-Cfatty acids; C-Cpolyolefins; C-Cpolydiolefins; C-Ccopolymers derived from polyolefins and vinyl aromatics; and C-Calkylated 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.
