    Abstract: A method for highly selectively producing a compound with a double bond represented by the following formula (III), the method comprising the following steps (A), (B), and (C):
    step (A): a step of reacting a compound represented by the following formula (I) and/or a compound represented by the following formula (II) with hydrogen in the presence of 0.1 parts by weight or more of a hydrogenation catalyst, thereby obtaining a reaction liquid,
    step (B): a step of removing the hydrogenation catalyst until the amount of the hydrogenation catalyst contained in the reaction liquid obtained in step (A) becomes 0.0010 parts by weight or less, thereby obtaining a hydrogenation catalyst-removed liquid,
    step (C): a step of obtaining a compound with a double bond represented by the following formula (III) in the presence of a dehydration catalyst from the hydrogenation catalyst-removed liquid obtained in step (B),

    wherein R 1 represents a hydrocarbon group,

    wherein R 2 represents a hydrocarbon group containing an aromatic ring,

            R 3 -CH=CH 2 (III)

    wherein R 3 represents an alkyl group, or the like.
