Catalysts selective for the preparation of mixed ketones from a mixture of carboxylic acids

摘要

Mixed ketones are prepared from a mixture of carboxylic acids in a process with high selectivity by using an improved catalyst. The catalyst contains zirconium dioxide or zirconium dioxide and titanium dioxide, and a Group 1 or 2 metal silicate or phosphate salt. The new catalyst is more selective toward the formation of the mixed ketone, as opposed to a symmetrical ketone.
