Abstract
A high-purity alcohol compound can be obtained by a method comprising passing a solution containing an ester compound and methanol and/or ethanol through a column packed with an anion exchange resin having methoxide and/or ethoxide as a counter anion to generate a methyl ester and/or ethyl ester, and distilling off the methyl ester and/or ethyl ester together with the methanol and/or ethanol.
Claims16
A method for producing an alcohol compound, the method comprising:
- passing a solution comprising an ester compound and methanol and/or ethanol through a column packed with an anion exchange resin having methoxide and/or ethoxide as a counter anion such that a methyl ester and/or ethyl ester is generated;
- and
- distilling off the methyl ester and/or ethyl ester together with the methanol and/or ethanol.
A method for producing an alcohol compound from an ester compound formed by protecting the alcohol compound with an acyl group, the method comprising:
- passing a solution comprising the ester compound and methanol and/or ethanol through a column packed with an anion exchange resin having methoxide and/or ethoxide as a counter anion such that the ester compound is decomposed into the alcohol compound and a methyl ester and/or ethyl ester comprising the acyl group;
- and
- distilling off the methyl ester and/or ethyl ester together with the methanol and/or ethanol.
