Process for preparing carbonyl catalyst

Abstract

Abstract M IS THE MOL NUMBER OF SAID SALT OF PALLADIUM OR SALT OF RHODIUM TO BE DISSOLVED, N IS THE NUMBER OF ELECTRIC CHARGE OF THE ACID RADICAL OF SAID SALT OF PALLADIUM OR SALT OF RHODIUM, P IS THE MOL NUMBER OF THE ACID IN THE AQUEOUS ACID SOLUTION DISSOLVING SAID SALT OF PALLADIUM OR SALT OF RHODIUM, Q IS THE NUMBER OF THE ELECTRIC CHARGE OF THE ACID RADICAL OF SAID ACID, AND, A IS THE MOL NUMBER OF SAID SALT OF PALLADIUM LESS THAN SALT OR RHODIUM, IS AT LEAST 4. THE CONCENTRATION OF SAID SALT BEING MAINTAINED LESS THAN THE SATURATION CONCENTRATION THROUGHOUT THE PERIOD OF CONTACT WITH ACTIVE CARBON. R=(M.N+P.Q) A 1. A PROCESS FOR THE PREPARATION OF A CATALYST FOR PRODUCING AN ALIPHATIC ALDEHYDE OR ALIPHATIC KETONE OF 2 TO 8 CARBON ATOMS, WHICH COMPRISES CONTACTING ACTIVE CARBON WITH AN AQUEOUS SOLUTION OF AN ACID SELECTED FROM THE GROUP CONSISTING OF HYDROCHLORIC ACID, FORMIC ACID, OXALIC SULFURIC ACID, NITRIC ACID, ACETIC ACID, FORMIC ACID, OXALIC ACID, MONOCHOLOACETIC ACID AND BENZENE SULFONIC ACID AND A METAL SALT SELECTED FROM THE GROUP CONSISTING OF CHLORIDE, BROMIDE, IODIDE, FLUORIDE, SULFATE, PHOSPHATE, NITRATE, CYANIDE, CHLORATE, PERCHLORATE, FORMATE, ACETATE, MONOCHLOROACETATE, BENZOATE AND NAPTHENATE OF AT LEAST ONE PLATINUM METAL SELECTED FROM THE GROUP CONSISTING OF PALLADIUM AND RHODIUM SO AS TO ADSORB SAID METAL SALT THEREON, WHEREIN SAID AQUEOUS ACID SOLUTION IS A SOLUTION OF SAID SALT OF SAID PLATINUM METAL DISSOLVED IN AN AQUEOUS SOLUTION OF AN ACID SO THAT ATOMIC RATIO R EXPRESSED BY THE FOLLOWING FORMULA
