METHOD OF ORGANIC NITRO-COMPOUNDS' CARBONYLATION REDUCTION

摘要

Reducing carbonylation of organic nitro-compounds mainly to organic amino compounds is achieved by a gas containing carbon monoxide and water, at 50 to 300 degrees C (100 to 200 degrees C), pressure of 0.l to 30 MPa (5 to 20 MPa) under the catalytic effect of a system consisting of 0.l to 20 (5 to 10) % by weight nitro-compounds of sulphur or its compounds, 0.01 to 5 (0.l to 2) % by weight hydroxide or alkoxide of alkaline metal and 0.005 to 7 % by weight vanadium oxide (V2O5) and/or oxygen (O2, O, peroxides).
