    摘要: Provided is a new organic-acid-based catalyst enabling production of a polyhydroxycarboxylic acid by direct dehydration polycondensation of a hydroxycarboxylic acid such as L-lactic acid, specifically, an organic-acid-based catalyst comprising an amine salt of a sulfonic acid or a phosphine salt of a sulfonic acid for production of polyhydroxycarboxylic acids such as poly-L-lactic acid.
