METHOD OF SYNTHESIS OF ACRYLIC ACID |
摘要 |
FIELD: organic chemistry and chemical technology. SUBSTANCE: acrylic acid can be synthesized efficiently by catalytic gas-phase oxidation of acrolein in the presence of molybdenum and vanadium-base catalyst obtained by using the definite substances as parent materials and containing individual metals as components of catalyst. Preferable example of this catalyst is ammonium meta-vanadate and at least one vanadium oxide at vanadium valency above 0 but less 5. Copper nitrate is used as a copper-containing parent material and at least one of antimony oxide as antimony-containing parent materials where antimony valency is above 0 but less 5. EFFECT: improved method of synthesis. 8 cl, 11 tbli
