ABSTRACT:
A process for partially oxidizing alcohols such as methanol, comprising the steps of a) introducing into a reactor unit containing a solid acid catalyst amounts of alcohol and oxygen; and a supercritical fluid (such as SCF CO.sub.2) mobile phase; and b) partially oxidizing the alcohol to its corresponding ether, aldehyde, ester or acid. In an advantageous embodiment, methanol is oxidized using an aerogel acid catalyst to produce methyl ether.
