Abstract
Official abstract text for this publication.
To provide a method for producing propionaldehyde directly from glycerol with high yield, gasified glycerol is brought into contact with a silica-type regular mesoporous body. More specifically, gasified glycerol is supplied to a catalyst layer containing a regular mesoporous body while heating the catalyst layer at a temperature ranging from 200 to 800° C. in such a manner that a W/F value can fall within the range from 0.001 to 1000 g·min/ml inclusive wherein W represents an amount (g) of a catalyst and F represents a supply rate (ml/min) of supplied glycerol.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing propionaldehyde wherein propionaldehyde is directly produced from glycerol, the method comprising contacting gasified glycerol with a silica-based regular mesoporous material. 2. The method for producing propionaldehyde according to claim 1 , wherein the regular mesoporous material has a pore size of 2.0 nm or more and 10.0 nm or less. 3. The method for producing propionaldehyde according to claim 1 , wherein the regular mesoporous material is FSM-16. 4. The method for producing propionaldehyde according to claim 1 , wherein the glycerol is biomass-derived glycerol. 5. The method for producing propionaldehyde according to claim 1 , wherein the gasified glycerol is supplied to the catalyst layer containing the regular mesoporous material. 6. The method for producing propionaldehyde according to claim 5 , wherein the glycerol is passed through the catalyst layer heated in the range of 200° C. to 800° C. 7. The method for producing glycerol according to claim 5 , wherein the supply of glycerol is carried out in a range of 0.001 g·min/ml or more and 1000 g·min/ml or less as W/F, where W is an amount (g) of the catalyst and F is a supply rate (ml/min) of the supplied glycerol.
