| titleOfInvention | DIRECT AND SELECTIVE OBTAINING OF ACETALDEHYDE FROM ACETIC ACID USING THE SUPPLIED METAL CATALYST |
| abstract | 1. A method for the selective and direct formation of acetaldehyde from acetic acid, in which: contact a feed stream containing acetic acid and hydrogen at a temperature in the range from 250 ° C to 350 ° C with a suitable hydrogenation catalyst containing:! (a) a first metal containing 0.5 to 1.0 wt% palladium and a second metal selected from the group consisting of iron, copper, gold, potassium, and combinations thereof, on a catalytic support selected from the group consisting of from silicon oxide and carbon, where the selectivity to acetaldehyde, based on the consumed acetic acid, is at least 60%. ! 2. The method of claim 1, wherein the catalyst support is silica. ! 3. A process according to claim 1, wherein the acetaldehyde selectivity based on acetic acid consumed is at least 70%. ! 4. A process according to claim 1, wherein the acetaldehyde selectivity, based on acetic acid consumed, is at least 80%. ! 5. The method of claim 1, wherein the hydrogenation to acetaldehyde is performed in the gas phase. ! 6. The method of claim 1, wherein said feed stream comprises an inert carrier gas. ! 7. A process according to claim 1, wherein the reagents consist of acetic acid and hydrogen in a molar ratio ranging from 100: 1 to 1: 100. ! 8. A process according to claim 1, wherein the reagents consist of acetic acid and hydrogen in a molar ratio ranging from 1:20 to 1: 2. ! 9. The method of claim 1, wherein the hydrogenation catalyst is selected from a bimetallic combination of palladium / gold (Pd / Au) or palladium / copper (Pd / Cu) supported on silicon oxide or carbon. ! 10. The method of selective and direct formation of acetaldehyde from acetic acid, in which: contact a stream of raw materials containing |
