Title:
DEHYDROGENATION OF ALKYLENE GLYCOL ETHERS TO ETHER KETONES AND ALDEHYDES
Document Type and Number:
WIPO Patent Application WO2002060849
Kind Code:
A3
Abstract:
A catalytic dehydrogenation of alkylene glycol ether to ether ketone or aldehyde is disclosed. The dehydrogenation is performed with copper chromite catalyst and at least 5 wt % of water based on alkylene glycol ether. It has been found that the selectively to formation of ether ketone or aldehyde increases with increasing the amount of water in the alkylene glycol ether.
