Summary:To provide a method capable of separating more efficiently than before from a mixture of methanol and methyl ester derived from a ≥3C carboxylic acid.SOLUTION: The method of separating methanol includes separating methanol from a mixture of methanol and methyl ester derived from a ≥3C carboxylic acid using a zeolite film where the zeolite film has an average pore diameter of 0.30 nm or larger and 0.73 nm or smaller, and contains zeolite having a Si/AL mole ratio of 2.0 or more.SELECTED DRAWING: Figure 1 【課題】メタノールと、炭素数３以上のカルボン酸より誘導されるメチルエステルとを含む混合物から、従来よりも、メタノールを高濃度で効率良く分離できる方法の提供。【解決手段】メタノールと、炭素数３以上のカルボン酸より誘導されるメチルエステルと、を含む混合物から、ゼオライト膜を用いて、メタノールを分離する方法であって、前記ゼオライト膜は、平均細孔径が０．３０ｎｍ以上０．７３ｎｍ以下であり、かつ、Ｓｉ／Ａｌモル比が２．０以上であるゼオライトを含む、ことを特徴とするメタノールの分離方法。【選択図】図１
