    • A process of producing α, β-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 α, β-unsaturated ether represented by Formula (3) below: R 1 R 2 CH-CR 3 (OR 4 ) 2 .••• (2) R 1 R 2 C=C-R 3 (OR 4 ) ••• (3) In Formulae (2) and (3), R 1 , R 2 and R 3 are each independently a hydrogen atom, an alkyl groups,an alkenyl group or an aryl group; R 4 is an alkyl group, an alkenyl group or an aryl group; the plurality of R 4 in Formula (2) may be the same or different from each other. It is an object of the invention to provide prcessses whereby catalysts are regenerated and used for an extended life and α, β-unsaturated ethers are produced efficiently and stably for an extended period of time.
    • 制备β-不饱和醚的方法包括在催化剂和具有至少一个能够氢键合的氢原子的化合物的存在下,在气相中热解由下式(2)表示的缩醛,以产生α,β 由下式(3)表示的不饱和醚:R1R2CH-CR3(OR4)2 ....(2)R1R2C = C-R3(OR4)...(3)在式(2)和(3)中,R1 ,R2和R3各自独立地为氢原子,烷基,烯基或芳基; R4是烷基,烯基或芳基; 式(2)中的多个R 4可以相同或不同。 本发明的一个目的是提供一种催化剂,其中催化剂被再生并且被使用延长的使用寿命,并且α-不饱和醚被有效且稳定地长时间地生产。
