A process is provided, by which a crude alkyladamantyl ester containing impurities tending to decompose the ester can be distilled without decomposition to give a purified alkyladamantyl ester efficiently. Specifically, a process of distilling a crude alkyladamantyl ester, for example, crude 2-methyl-2-adamantyl methacrylate in the presence of a heterocyclic compound and/or a basic compound, for example, 3-ethyl-3-hydroxymethyloxetane or diglycidylbisphenol A. |
