PROCESS FOR PREPARATION OF CATALYSTS FOR PRODUCTION OF ACRYLIC ACID.

摘要

The catalysts are prepared, as to supply sources of vanadium and copper, under the conditions that (A) ammonium metavandate and vanadium oxides in which the valency of vanadium is larger than 0 and smaller than 5 are used as a supply source of vanadium, and copper nitrate is used as a supply source of copper; (B) ammonium metavanadate is used as a supply source of vanadium, and copper nirate and copper oxides in which the valency of copper is larger than 0 and smaller than 2 are used as a supply source of copper, or (C) ammonium metavandate and vanadium oxides in which the valency of vanadium is larger than 0 and smaller than 5 are used as copper oxides in which the valency of copper is larger than 0 and smaller than 2 are used as a supply source of copper.
