Claims
- 1. A process for producing higher alcohols which comprises contacting carboxylic acid alkyl esters having about 5 to about 24 carbon atoms in the carboxylic acid portion and hydrogen with a catalyst corresponding in the oxide form to the formula
- CuZn.sub.0.5-2 Mn.sub.0.01-0.50 O.sub.x
- wherein x is the number of oxygen atoms needed per formula unit for electrical neutrality wherein the process is carried out at a temperature of about 150.degree. C., to about 250.degree. C., and a pressure of about 200 to about 400 bar to a saponification number not greater than 5.
- 2. The process of claim 1 wherein the temperature is about 180.degree. to about 230.degree. C. and the pressure is about 200 to about 350 bar.
- 3. The process of claim 1 wherein the catalyst corresponds to the formula
- CuZn.sub.0.8-1.5 Mn.sub.0.05-0.2 O.sub.x.
- 4. The process of claim 1 wherein the catalyst is in the form of moldings.
- 5. The process of claim 4 wherein the catalyst has a pore volume (determined by Hg porosimetry) of about 0.15 to about 1.2 cm.sup.3 /g.
- 6. The process of claim 5 wherein the catalyst has pore volume of about 0.2 to about 0.7 cm.sup.3 /g.
- 7. The process of claim 1 wherein the catalyst has an average side crush strength, measured on cylindrical moldings having a diameter of 4.5 mm and a length of 4.5 mm, of at least 40N.
- 8. The process of claim 7 wherein the catalyst has an average side crush strength is at least 60N.
- 9. The process of claim 1 wherein the catalyst has a BET specific surface area of about 20 to about 180 m.sup.2 /g.
- 10. The process of claim 9 wherein the catalyst has a BET specific surface area is about 20 to about 120 m.sup.2 /mg.
