Method of vanadyl dihydroorthophosphate preparation
Description
A method for preparation of vanadyl dihydroorthophosphate is developed to reduce duration of synthesis and to increase of described product yield. The method includes interaction of vanadium compounds containing oxide with H3PO4 during heating in the presence of hydroxylamine or its V:A3PO4:NH2OH=1:(2-4):(1.2-1.0) and at 110-130 deg C. Product yield is 96.9-98.3%
