Slightly acid odor. Soluble in water and glycerol, ethanol-soluble. Melting point 253 C (Anhydrous).Strong thermal decomposition of hydrogen at the grass and sodium. Chemical analysis using the reagent to determine arsenic and phosphorus content, but also for disinfectants, dyes and other media. Using acid reaction with sodium bicarbonate, to maintain alkaline solution, remove < Fe3 + / SUP>, filtration, the filtrate into formic acid, was weak acid solution, evaporation and crystallization in that the goods.
the production of oxalic acid and formic acid intermediates, but also for the production of dimethyl formamide so.
