    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.

    摘要： The invention relates to a process for preparing omega-amino acids or their esters, which is characterized by the following steps: c) ozonolysis of unsaturated fatty acids or fatty acid derivatives, d) reductive amination of the reaction mixture obtained from the reaction with ozone, to give the omega-amino acid or ester thereof, the reaction being carried out with a C1-C5 alcohol in a mixture with at least 0.5% by weight of water as solvent, based on the total amount of solvent.
