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.
