Disubstituted vanadyl ortho-phosphate and its preparation method
Description
The method of disubstituted vanadyl ortho-phosphate VOHPO4x2.5H2O preparation by means of (VO)3(PO4)3x10H2O phosphoric acid treatment at 55-65 deg C and stoichiometric ratio is presented. The given method allows to produce the preparation of 99.3-99.8% purity with the yield - 98.7-99.6%. VOHPO4x2.5H2O synthesized is applicable in analytical and preparative chemistry, for physicochemical methods of investigation as a chemical reagent
