    Abstract: Process for obtaining formic acid by thermal separation of a stream comprising formic acid and a tertiary amine (I), in which, in step (a), a liquid stream comprising formic acid, methanol, water and tertiary amine (I) is produced by combining methyl formate, water and tertiary amine (I), from there in step (b), methanol is separated off and in step (c), formic acid is removed by distillation from the liquid stream obtained in a distillation apparatus, wherein, when methyl formate, water and tertiary amine (I) are combined, methyl formate, water and optionally tertiary amine (I) are first introduced in step (a1) in a molar ratio of 0≦n(amine to a1)/n(mefo to a1)≦0.1, and from 70 to 100% of the hydrolysis equilibrium possible is set and then, in step (a2), tertiary amine (I) is introduced in a molar ratio of 0.1≦n(amine to a2)/n(mefo to a1)≦2, and the mixture is reacted.

    Abstract: The present invention relates to a process for preparing carboxylic acid esters, comprising the reaction of at least one primary monoalcohol or of a mixture of a primary monoalcohol and at least one alcohol different therefrom in the presence of a transition metal carbene complex catalyst K which has, as central atom M, at least one transition metal atom of group 8, 9 or 10 of the Periodic Table of the Elements (IUPAC) and at least one monodentate N-heterocyclic carbene ligand, in the presence of a base, wherein the catalyst K is prepared by reacting a transition metal compound V which has at least one transition metal atom of group 8, 9 or 10 of the Periodic Table of the Elements (IUPAC), but no carbene ligand, with an imidazolium salt in the presence of the primary monoalcohol and the base, the reaction being carried out without dilution.
