Use of phosphomolybdic acid

Mainly used as redox catalysts, such as direct oxidation of methane to formaldehyde, propylene oxidation to acrolein acetone, propylene ammoxidation to acrylonitrile, etc. Also used as a weighting agent for silk and leather. Raw materials and analytical reagents for preparing organic pigments are used to test the interaction between alkaloids, urea, xanthine, creatinine, ammonium, amine and some metals, and to analyze and determine antimony, cerium, copper, thallium and vanadium in trace amounts. Pigment used with hematoxylin for nerve dyeing, corrosion inhibitor and expressway road signs.
