Abstract: The invention relates to a method for producing monoethylene glycol (MEG) via the metal-catalysed reaction of an oxalic acid dialkyl ester of formula (I), in which R
1 and R
2 each independently of one another represent methyl, ethyl, n-propyl or iso-propyl groups, with hydrogen (H
2 ), wherein the oxalic acid dialkyl ester (I) is used in the form of a melt or dissolved in a solvent, oxalic acid dialkyl ester (I) and H
2 are used in a molar ratio of H
2 :oxalic acid dialkyl ester (I) in the region of 4.0 to 30, and the reaction is carried out continuously in a reactor at a sectional density of ≥ 10 m/s, a temperature in the region of 150 to 270°C, a pressure in the region of 150 to 390 bar and in the presence of a chrome-free, heterogeneous, copper-containing catalyst.-

Abstract: The present invention relates to a method for producing ethylene oxide by reacting ethylene with oxygen in the presence of at least one catalyst containing silver, wherein the reaction occurs in a reactor that has a catalyst packing having at least two layers (i) and (ii), and the silver content of the catalyst in the layer (i) is lower than the silver content of the catalyst in the layer (ii). The catalyst packing preferably comprises a further layer (a), with which the reaction mixture comes in contact prior to layers (i) and (ii). According to the invention, the silver content of the catalyst in the layer (a) is higher than the silver content of the catalyst in the layer (i).
