Abstract:
1. A process for the preparation of a carboxylic acid salt by dehydrogenation of a primary alcohol corresponding to the formula: wherein n is an integer ranging from 2 to 20; R 1 and R 2 are independently hydrogen; —(CH 2 ) x —(CH 3 ), x being an integer ranging from 0 to about 19; —(CH 2 ) y —OH, y being an integer ranging from 1 to about 20; (CH 2 ) z —COOH, z being an integer ranging from 1 to about 19; or phosphonomethyl, the process comprising: contacting an alkaline mixture comprising said primary alcohol with a dehydrogenation catalyst, said catalyst comprising a copper-containing active phase at the surface thereof and a supporting structure, wherein the supporting structure has a yield strength of at least about 100 Mpa and comprises at least about 10% by weight non-copper metal such that the supporting structure is resistant to deformation under the conditions of the dehydrogenation reaction.
