Abstract: The present invention is a method for producing a cyclopentyl alkyl ether compound represented by formula (1): R1—O—R2 (wherein, R1 represents an alkyl group having 1 to 10 carbon atoms that may have a substituent or a cycloalkyl group having 3 to 8 carbon atoms that may have a substituent, and R2 represents a cyclopentyl group that may have a substituent), wherein a cyclopentene that may have a substituent is reacted with an alcohol compound represented by formula (2): R1OH (wherein R1 represents the same as described above) in the presence of an acidic zeolite having a silica/alumina ratio of 80 or higher. The present invention provides a method for producing a cyclopentyl alkyl ether compound, wherein a reaction can be carried out in a liquid phase, catalyst activity is less lowered over time (long catalyst life), and a desired cyclopentyl alkyl ether compound can be continuously produced with high reaction efficiency and long-term stability even when a large amount of raw material is fed.

Abstract: Provided are a membrane separation method and a membrane separation device that enable membrane separation of a hydrocarbon mixture with high separation efficiency. The membrane separation method includes a step (A) of exposing a zeolite membrane to an atmosphere having a dew point of −20° C. or lower and a step (B) of using the zeolite membrane to perform membrane separation of a hydrocarbon mixture after step (A). The membrane separation device includes: a membrane separation module including a housing and a zeolite membrane that is housed in the housing and is configured to perform membrane separation of a hydrocarbon mixture; a feedstock supply mechanism configured to supply the hydrocarbon mixture into the membrane separation module; and a gas supply mechanism configured to supply a gas having a dew point of −20° C. or lower into a space in which the zeolite membrane is housed in the membrane separation module.
