ABSTRACT:
A process for isomerizing epoxides to aldehydes is disclosed. The process uses a metal-exchanged zeolite catalyst wherein the zeolite contains an alkali metal and one or more second exchangeable metals from Group IIA, IB, IIB, or IIIB. The catalysts are easily made by combining alkali metal-exchanged zeolites with aqueous solutions that contain halides or nitrates of the second metal. The process is useful for vapor-phase isomerization of propylene oxide to propanal.
