Title:
DIRECT AND SELECTIVE PRODUCTION OF ACETALDEHYDE FROM ACETIC ACID UTILIZING A SUPPORTED METAL CATALYST
Document Type and Number:
WIPO Patent Application WO/2010/014146
Kind Code:
A3
Abstract:
A process for the selective production of acetaldehyde by vapor phase reaction of acetic acid over a hydrogenating catalyst composition to form acetaldehyde is disclosed and claimed. In an embodiment of this invention reaction of acetic acid and hydrogen over platinum and iron supported on silica selectively produces acetaldehyde in a vapor phase at a temperature of about 300°C.
