Abstract
Official abstract text for this publication.
A metal oxide catalyst involved in a hydrogenation reaction in which a ketone is converted into an alcohol, a method of preparing the metal oxide catalyst, and a method of preparing an alcohol using the same are provided. The metal oxide catalyst has a spinel structure represented by the following Formula 1: XAl 2 O 4 , <Formula 1> wherein X represents nickel or copper.
First claim
Opening claim text (preview).
What is claimed is: 1. A metal oxide catalyst involved in a hydrogenation reaction in which a ketone is converted into an alcohol, wherein the metal oxide catalyst has a spinel structure represented by the following Formula 1: XAl 2 O 4 , <Formula 1> wherein X represents nickel and a content of the nickel in the metal oxide catalyst is in a range of 35 to 65% by weight. 2. A metal oxide catalyst involved in a hydrogenation reaction in which a ketone is converted into an alcohol, wherein the metal oxide catalyst has a spinel structure represented by the following Formula 1: XAl 2 O 4 , <Formula 1> wherein X represents copper and a content of the copper in the metal oxide catalyst is in a range of 40 to 55% by weight. 3. The metal oxide catalyst of claim 1 , wherein the metal oxide catalyst has an average particle size of 100 to 1,000 nm. 4. A method of preparing an alcohol, comprising: allowing hydrogen to react with a ketone in the presence of the metal oxide catalyst defined in claim 1 to convert the ketone into an alcohol. 5. The method of claim 4 , wherein the ketone is methyl isobutyl ketone. 6. The method of claim 5 , wherein the alcohol is methyl isobutyl carbinol. 7. The method of claim 4 , wherein the reaction is carried out at a temperature of 70 to 150° C. 8. The method of claim 4 , wherein the reaction is carried out at a pressure of 0.0 to 3.0 barg. 9. The method of claim 4 , wherein the reaction is carried out at a liquid hourly space velocity of 0.1 to 1.7 hr −1 . 10. The method of claim 4 , wherein the ketone and the hydrogen are allowed to react at a molar ratio of 1:4 to 8. 11. The metal oxide catalyst of claim 2 , wherein the metal oxide catalyst has an average particle size of 100 to 1,000 nm.
