A method for producing 2-methoxyacetic acid by oxidizing 2-methoxyethanol in a reaction device using oxygen at a temperature of 20 to 100&#xb0; 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 &#x2264;0.80 of the mass ratio of the added 2-methoxyethanol to the added 2-methoxyethanol plus water.

Method for producing 2-methoxyacetic acid

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&#xb0; 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 of0.002&#x2264;(Pt)/[(oxydiol (I))+(oxydicarboxylic acid (II))]&#x2264;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.

Process for preparing an anticorrosion component for an antifreeze

The present invention relates to A process for the production of a molding, comprising (I) providing a zeolitic material; (II) mixing the zeolitic material provided in step (I) with one or more binders; (III) kneading of the mixture obtained in step (II); (IV) molding of the kneaded mixture obtained in step (III) to obtain one or more moldings; (V) drying of the one or more moldings obtained in step (IV); and (VI) calcining of the dried molding obtained in step (V); wherein the zeolitic material provided in step (I) displays a water adsorption ranging from 1 to 15 wt.-% when exposed to a relative humidity of 85%, as well as to a molding obtainable or obtained according to the inventive process in addition to a molding per se and to their respective use.
