The invention discloses a 2-alkoxycyclohexanol dehydrogenation method. The 2-alkoxycyclohexanol dehydrogenation method comprises the following step: under the catalytic dehydrogenation condition, enabling 2-alkoxycyclohexanol to be in contact with an additive and a dehydrogenation catalyst including active components of the eighth-group metallic elements, wherein the additive is an acid additive and/or an alkaline additive. By adoption of the technical scheme, catechol derivatives can be effectively synthesized.
