Claims
- 1. A process for hydrogenating a bound oxygen-containing organic compound, said process comprising:
- contacting said organic compound as a vapor and hydrogen with a reduced catalyst composition comprising copper, aluminum, and a metal, X, selected from the group consisting of magnesium, zinc, titanium, zirconium, tin, nickel, cobalt and mixtures thereof, under hydrogenation conditions, said catalyst having been made by a process comprising:
- reducing a mixture of oxides of copper, aluminum, and X by heating in the presence of a reducing gas under activation conditions which comprise a temperature that gradually increases from a starting temperature of about 40.degree. to 75.degree. C. to a final temperature of about 150.degree. to 250.degree. C. at a rate of about 3.degree.-18.degree. C./hr.
- 2. A process according to claim 1 wherein said organic compound comprises a mono-ester, a di-ester, or a mixture thereof.
- 3. A process according to claim 1 wherein said organic compound comprises methyl acetate, butyl acetate, dibutyl succinate, and/or methyl propionate.
- 4. A process according to claim 1 wherein said organic compound comprises a nonaromatic ester; a nonaromatic dibasic acid; an ester of a hydroaromatic acid; a monoalkyl oxalate; a dialkyl oxalate; and a straight or branched chain, saturated or unsaturated aldehyde.
- 5. A process according to claim 1 wherein the reducing step is at a starting temperature of about 50.degree. C. to a final temperature of about 180.degree..
- 6. A process according to claim 1 wherein said organic compound is contacted with said catalyst which has been activated under conditions comprising a temperature that increases at a rate of about 3.degree.-6.degree. C./hr.
- 7. A process according to claim 5 wherein said organic compound is contacted with said catalyst which has been activated under conditions comprising a temperature that increases at a rate of about 3.degree.-6.degree. C./hr.
- 8. A process according to claim 1 wherein said catalyst has a Cu:Al:X weight ratio within the range of about 10-80:1-30:10-80.
