摘要：
A method of producing a diol derivative efficiently and to high purity is provided. Specifically, the present invention relates to a method of producing a diol derivative having, as a fundamental step, a step of obtaining an α-hydroxycarboxylic acid ester by reacting (i) one or more 1,2-diols or (ii) a 1,2-diol and a primary alcohol as starting material(s) with oxygen in the presence of a catalyst comprising metal loaded on a carrier, further hydrolyzing the α-hydroxycarboxylic acid ester to obtain α-hydroxycarboxylic acid, and subjecting the α-hydroxycarboxylic acid to polycondensation.
