Abstract: A process for preparing an anticorrosion component for an antifreeze by oxidizing an oxydiol of the formula (I) 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. The catalyst contains platinum to form an oxydicarboxylic acid of the formula (II) The process has the steps of conducting the oxidation (a) at a molar ratio of 0.002≤n(Pt)/[n(oxydiol (I))+n(oxydicarboxylic acid (II))]≤0.019; (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.

Abstract: A method for producing 2-methoxyacetic acid by oxidizing 2-methoxyethanol in a reaction device using oxygen at a temperature of 20 to 100° C. and an oxygen partial pressure of 0.01 to 2 MPa in the presence of water and a heterogeneous catalyst containing platinum, in which the method is carried out semi-continuously or continuously, and 2-methoxyethanol is added to the reaction device in a temporally and/or spatially distributed manner such that temporally and spatially, the mass ratio of 2-methoxyethanol to 2-methoxyethanol plus water per volume element in the reaction device is constantly ≤0.80 of the mass ratio of the added 2-methoxyethanol to the added 2-methoxyethanol plus water.
