A method for the breakdown of formates in formate-containing substance mixtures, wherein the formate-containing substance mixtures are reacted in the presence of at least one lanthanum-containing heterogeneous catalyst at a temperature of 80 to 180 °C and at a pressure of 0.1 to 60 bar, and the formate-containing substance mixtures have a pH of 6.5 to 10. Formate-containing substance mixtures is understood to mean, in particular, substance mixtures comprising carbonyl compounds, which were formed, for example, by an aldol reaction of alkanones or alkanals with formaldehyde, such as, for example, methylolalkanals and the respective hydrogenation products thereof. Said products also contain formates in addition to the aforementioned carbonyl compounds. |
