Abstract
Chemical processes leading to inactivation of vanadium sulfuric acid catalysts by arsenic(III) oxide vapor were studied. The interaction and solubility in the system VO(H2AsO4)2-VOAsO4-H3AsO4-H2O and the composition of oxovanadium arsenate in a mixed oxidation state, used as a starting substance in synthesis of (VIVO)(VVO)2(As2O7)2, were examined.
