CATALYSTS FOR HYDROGENATION OF CARBOXYLIC ACID

Document Type and Number:

WIPO Patent Application WO/2001/021306

Kind Code:

A1

Abstract:

A catalyst for the hydrogenation of carboxylic acids which comprises activated carbon having deposited thereon active metals including ruthenium and tin, characterized in that the activated carbon is one produced by a process comprising activating a carbonaceous material with zinc chloride and then burning it; a catalyst for the hydrogenation of carboxylic acids which comprises activated carbon having deposited thereon active metals including ruthenium and tin, characterized in that the activated carbon, before deposition of the active metals, had specific pore properties, in particular, such properties that the volume of pores having a pore radius not smaller than 10 Å but not larger than 100 Å was from 0.5 to 2.0 cm?3¿/g; and a process for producing a primary alcohol which comprises reacting at least one starting material selected from the group consisting of carboxylic acids and acid anhydrides with hydrogen gas in the presence of water and either of the catalysts to hydrogenate the starting material
