摘要 |
Process for the preparation of alpha, omega-alkanedicarboxylic acids of the general formula I <IMAGE> I in which A is an alkylene radical having 4-14 C atoms by reacting a cycloalkene of the general formula II <IMAGE> II in which A has the abovementioned meaning with ozone in the presence of an inert solvent, catalytically hydrogenating the peroxide solution formed, followed by oxidation of the dialdehyde formed to the diacid of the formula I in the presence of an inert aprotic solvent.
