Abstract

A polymeric catalyst, and methods of using the catalyst, comprising at least one of a monosulfonated ion exchange resin, monosulfonated gel, and macroreticular resin having a particle size of less than 560 μm and metal impregnated within the resin, where the metal is palladium, platinum, iridium, rhodium, ruthenium, copper, gold, and/or silver.

Claims (13)

1. A polymeric catalyst comprising:

at least one monosulfonated gel having a particle size of less than 560 μm; and

metal impregnated within the resin, the metal being selected from at least one of palladium, platinum, iridium, rhodium, ruthenium, copper, gold, and silver.

2. The polymeric catalyst of claim 1 further comprising a polydispersity of no more than 1.6.

3. The polymeric catalyst of claim 1 wherein the metal comprises 0.1 to 15 percent metal ion, based on dry weight of the catalyst, distributed therein.

4. The polymeric catalyst of claim 1 wherein the metal comprises palladium.

5. The polymeric catalyst of claim 1 wherein the monosulfonated gel comprises a surface area of less than 0.1 m 2 /g and 1-10% by weight of a crosslinker.

6. The polymeric catalyst of claim 1 wherein the at least one monosulfonated gel comprises a particle size of 300-350μm.

7. A method of making a ketone comprising:

providing a polymeric catalyst of at least one monosulfonated gel resin having a particle size of less than 400 μm and metal impregnated within the resin, the metal being selected from at least one of palladium, platinum, iridium, rhodium, ruthenium, copper, gold, and silver, the catalyst having 0.1 to 15 percent metal based on dry weight of the catalyst;

contacting a ketone reactant and hydrogen with said polymeric catalyst to produce a saturated ketone product at a yield of 5-60% and a selectivity of 90-99%.

8. The polymeric catalyst of claim 1 , wherein said polymeric catalyst is suitable for catalyzing a process in which a ketone reactant and hydrogen are brought into contact with said polymeric catalyst to produce a saturated ketone product.

9. The polymeric catalyst of claim 1 , wherein said polymeric catalyst is suitable for catalyzing a process in which acetone and hydrogen are brought into contact with said polymeric catalyst to produce methyl isobutyl ketone.
