Vapor-phase synthesis of ethyl tert-butyl ether on heteropoly acid-polymer composite film catalysts
H3PMo12O40-polysulfone and H3PMo12O40-polyphenylene oxide composite film catalysts were prepared by a membrane preparation technique. They showed the higher catalytic activities than H3PMo12O40 in the vapor-phase synthesis of ethyl tert-butyl ether.
