    摘要: A process for preparing an alpha, omega-dicarboxylic acid or an ester thereof, which includes (a) subjecting at least one unsaturated fatty acid or fatty acid derivative to ozonolysis to obtain an ozonolysis reaction mixture; and (b) oxidizing the ozonolysis reaction mixture with an oxidizing agent in the presence of an acid catalyst to obtain an oxidized reaction mixture comprising at least one alpha, omega-dicarboxylic acid or ester; wherein the process is performed using a solvent and the acid catalyst has a pKa of less than or equal to zero, as measured at 25° C.
