    Abstract: This invention relates to processes for making nitro compounds derived from C 2 -C 30 unsaturated fatty acids; C 2 -C 30 unsaturated fatty oils; esters derived from the reaction of C 1 -C 20 alcohols with unsaturated C 2 -C 30 fatty acids; C 2 -C 20 polyolefins; C 4 -C 20 polydiolefins; C 8 -C 20 copolymers derived from polyolefins and vinyl aromatics; and C 4 -C 30 alkylated 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.

    Abstract: A method of preparing nitroform (trinitromethane) by nitrating a starting material which is dissolved or suspended in sulphuric acid. A nitrating agent consisting of nitric acid, nitrate salts or nitrogen pentoxide is added to the sulphuric acid solution/suspension at a temperature from -10 DEG C to +80 DEG C. The starting material is selected from a group consisting of a) a gem-dinitroacetyl urea with the general formula wherein Y is H or a group, wherein Y is an alkoxy or amino group, and salts thereof; b) gem-dinitroacetyl guanidine, and c) 4,6-hydroxypyrimidine. In nitration, a gem-trinitro compound is formed which in hydrolysis splits off nitroform.
