Abstract
Official abstract text for this publication.
In a method for producing hydrogen and carboxylic acid, a primary alcohol of 1 to 7 carbon atoms and water are reacted by being continuously introduced into a flow reactor packed with a solid catalyst consisting of an alloy of ruthenium and tin on a support and passed through the reactor under temperature and pressure conditions at which the water assumes a gaseous state. This method enables hydrogen and carboxylic acid to be produced in a high yield or at a high purity from a primary alcohol and water in a short time and by simple operations.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing hydrogen and carboxylic acid, comprising a step of reacting a primary alcohol of 1 to 7 carbon atoms with water by continuously introducing the primary alcohol of 1 to 7 carbon atoms and water into a flow reactor packed with a solid catalyst consisting of an alloy of ruthenium and tin on a support and passing the primary alcohol of 1 to 7 carbon atoms and water through the flow reactor under temperature and pressure conditions at which the water assumes a gaseous state. 2. The production method of claim 1 , wherein the flow reactor has therein a temperature of between 185° C. and 350° C. and a pressure of from 0.1 to 15 MPa. 3. The production method of claim 1 , wherein the alloy of ruthenium and tin has a ruthenium content of from 25 to 200 parts by weight per 100 parts by weight of tin. 4. The production method of claim 1 , wherein the primary alcohol of 1 to 7 carbon atoms is ethanol and acetic acid is produced as the carboxylic acid. 5. The production method of claim 1 , wherein the primary alcohol of 1 to 7 carbon atoms and water introduced to the flow reactor have a residence time therein of not more than 60 seconds. 6. The production method of claim 1 , wherein the solid catalyst is composed of particles of the alloy of ruthenium and tin supported on a metal oxide or carbonaceous material.
