Abstract: A process for preparing an anticorrosion component for an antifreeze by oxidizing an oxydiol (I) in which x is 0 (zero) or a positive integer from 1 to 10 with molecular oxygen at a temperature of 20 to 100° C. and a partial oxygen pressure of 0.01 to 2 MPa in the presence of water and of a heterogeneous catalyst comprising platinum to form an oxydicarboxylic acid (II) in which y is 0 (zero) or a positive integer from 1 to 10, in which the oxidation is conducted (a) at a molar ratio of 0.002≤n(Pt)/[n(oxydiol (I))+n(oxydicarboxylic acid (II))]≤0.019 where “n(Pt)” Is the molar amount of platinum, “n(oxydiol (I))” is the molar amount of oxydiol (I) and “n(oxydicarboxylic acid (II))” Is the molar amount of oxydicarboxylic acid (II); (b) at a concentration of water of 50% to 95% by weight in the liquid phase; and (c) at a pH of 1 to 7.
