Patent ID: 8759594

Claim:
A process for hydrogenating at least one oligo- or polyester comprising: hydrogenating the at least one oligo- or polyester in the presence of a shaped catalyst body whose precursor is obtained by a process comprising: (i) combining an oxidic material comprising copper oxide, aluminum oxide and at least one additional metal oxide of a metal selected from the group consisting of lanthanum, tungsten, molybdenum, titanium, zirconium, and iron, and at least one second material selected from the group consisting of pulverulent metallic copper, copper flakes, pulverulent cement, graphite, and a mixture thereof with the oxidic material to obtain a catalyst precursor mixture, (ii) shaping the catalyst precursor mixture to obtain the shaped catalyst body, and (iii) calcining the shaped catalyst body wherein the oxidic material is obtained by simultaneous or successive precipitation of an active copper component, an aluminum component, and a component of at least one of oxide of a metal selected from the group consisting of lanthanum, tungsten, molybdenum, titanium, and zirconium, subsequent drying and a first calcination and wherein the at least one oligo- or polyester is obtained by esterifying a dicarboxylic acid solution with a diol or diol mixture, then adding a base selected from the group consisting of lithium alkoxide, potassium alkoxide, and sodium alkoxide, wherein the dicarboxylic acid solution comprises dicarboxylic acids obtained as a waste product in the oxidation of cyclohexane with air to give cyclohexanone and cyclohexanol, by extraction of the oxidized mixture with water.
