Title: Process for producing .alpha., .beta.-unsaturated ether

Abstract: A process of producing .alpha.,.beta.-unsaturated ethers includes pyrolyzing an acetal represented by Formula (2) below in a gas phase in the presence of a catalyst and a compound having at least one hydrogen atom capable of hydrogen bonding to produce an .alpha.,.beta.-unsaturated ether represented by Formula (3) below: R.sub.1R.sub.2CH--CR.sub.3(OR.sub.4).sub.2 (2) R.sub.1R.sub.2C.dbd.C--R.sub.3(OR.sub.4) (3) In Formulae (2) and (3), R.sub.1, R.sub.2 and R.sub.3 are each independently a hydrogen atom, an alkyl group, an alkenyl group or an aryl group; R.sub.4 is an alkyl group, an alkenyl group or an aryl group; the plurality of R.sub.4 in Formula (2) may be the same or different from each other.
