Process for obtaining formic acid by thermal separation of a stream comprising formic acid and a tertiary amine (I), in which a liquid stream comprising formic acid and a tertiary amine (I) in a molar ratio of from 0.5 to 5 is produced by combining tertiary amine (I) and a formic acid source, from 10 to 100% by weight of the secondary components present therein are separated off and formic acid is removed by distillation in a distillation apparatus at a bottom temperature of from 100 to 300&#xb0; C. and a pressure of from 30 to 3000 hPa abs from the liquid stream obtained, the bottom discharge from the distillation apparatus being separated into two liquid phases and the upper liquid phase being recycled to the formic acid source and the lower liquid phase being recycled for separating off the secondary components and/or to the distillation apparatus.

Process for the preparation of formic acid

Processes comprising: providing a mixture comprising monoethylene glycol and diethylenetriamine; and subjecting the mixture to extractive distillation with a diethylenetriamine-selective solvent comprising triethylene glycol to provide a first stream comprising monoethylene glycol and a second stream comprising diethylenetriamine; wherein the first stream is substantially free of diethylenetriamine, and wherein the second stream is substantially free of monoethylene glycol.

Process for the distillative separation of mixtures comprising monoethylene glycol and diethylentriamine

A process for preparing ethylene amines and ethanolamines by hydrogenative amination of monoethylene glycol and ammonia in the presence of a catalyst, wherein the process is carried out in two process stages in which

Method for producing ethylene amines ethanol amines from monoethylene glycol (MEG)

A process for preparing ethylene amines and ethanolamines by hydrogenative amination of monoethylene glycol and ammonia in the presence of a catalyst, wherein a catalyst having an active composition comprising ruthenium and cobalt and no further additional metal of group VIII and also no metal of group IB is used in the form of shaped catalyst bodies which in the case of a spherical shape or rod shape in each case have a diameter of &#x3c;3 mm, in the case of a pellet shape have a height of &#x3c;3 mm and in the case of all other geometries in each case have an equivalent diameter L=1/a' of &#x3c;0.70 mm, where a&#x2032; is the external surface area per unit volume (mm/mm) and: where Ais the external surface area of the shaped catalyst body (mm) and Vis the volume of the shaped catalyst body (mm), is proposed.
