Homogeneous process for the hydrogenation of carboxylic acids and derivatives thereof |
摘要 |
A homogenous process for the hydrogenation of the carboxylic acids and/or derivatives thereof in the presence of a catalyst comprising ruthenium, rhodium, iron, osmium or palladium, and an organic phosphine is described in which the hydrogenation is carried out in the presence of at least about 1% by weight water. A process for regenerating a catalyst comprising ruthenium, rhodium, iron, osmium or palladium and an organic phosphine is also described in which the regeneration is carried out in the presence of hydrogen and water. |

1. A process for regenerating a catalyst comprising:
forming a reaction mixture comprising water and a catalyst deactivated or poisoned by carbon monoxide, wherein the deactivated or poisoned catalyst comprises:
(a) ruthenium, rhodium, iron, osmium or palladium; and(b) an organic phosphine; and regenerating the deactivated or poisoned catalyst in the presence of hydrogen, and at a temperature of from about 150° C. to about 350° C., via the water gas shift reaction; wherein the regenerating is carried out in the absence of halide. |
