Volumetric and Gravimetric Analytical Methods for Organic Compounds

“…Nitro Compounds. Xitro compounds (and nitroso compounds) have been determined by heating with a chromic-sulfuric acid mixture at 150°f ollowed by reduction to XH3 with Devarda's alloy (136). The XH3 is determined acidimetrically Xitro compounds containing the dinitrophenyl group can be titrated quantitatively in acetone or pyridine with tetrabutylammonium hydroxide in benzene-methanol (187).…”
