Beschreibung
Zusammenfassung:	The invention provides a process for vacuum distillation of at least one organic compound by means of a vacuum unit comprising a vacuum pump (11) and an absorption apparatus (9) connected upstream of the vacuum pump and comprising an absorption liquid, wherein the absorption liquid is different from the compound to be distilled and forms an addition compound therewith and/or the absorption liquid is identical to the compound to be distilled. The invention further also relates to the use of a vacuum unit comprising a vacuum pump (11) and an absorption apparatus (9) connected upstream of the vacuum pump and comprising an absorption liquid according to the invention. L'invention concerne un procédé de distillation sous vide d'au moins un composé organique à l'aide d'une unité à vide comprenant une pompe à vide (11) et un dispositif d'absorption (9) relié en amont de la pompe à vide et comprenant un liquide d'absorption, le liquide d'absorption étant différent du composé à distiller et formant avec celui-ci un composé d'ajout et/ou le liquide d'absorption étant identique au composé à distiller. L'invention concerne en outre l'utilisation d'une unité à vide comprenant une pompe à vide (11) et un appareil d'absorption (9) relié en amont de la pompe à vide et comprenant un liquide d'absorption selon l'invention.
