Abstract
A PROCESS FOR PRODUCING A HYDROGENATED ESTER BY HYDROGENATING AN UNSATURATED GROUP-CONTAINING ESTER HAVING A SPECIFIC STRUCTURE BY USING A HYDROGENATING CATALYST SO AS TO OBTAIN A HYDROGENATED ESTER WITH A HIGH SELECTIVITY. IT IS PREFERRED THAT THE UNSATURATED GROUP-CONTAINING ESTER AS THE RAW MATERIAL IS DILUTED WITH AN INERT SOLVENT AND/OR THE CONCENTRATION OF CARBOXYLIC ACID CONTAINED IN THE RAW MATERIAL IS MADE 1 WT.OR LESS SO AS TO EFFECT A HYDROGENATION REACTION. THE HYDROGENATING CATALYST BE ONE COMPRISING AT LEAST ONE METAL SELECTED FROM GROUP VIII ELEMENTS, GROUP IX ELEMENTS, AND GROUP X ELEMENTS IN THE PERIODIC TABLE, AND PREFERABLY HAS AN ACIDITY OF 1.0 X 10-1 MMOL/G LESS.
