摘要:
The present invention relates to a process for vacuum distillation of at least one organic compound by means of a vacuum unit (8) comprising an absorption liquid, wherein the absorption liquid is different from the organic liquid to be distilled and forms an addition compound therewith and/or the absorption liquid is identical to the organic compound to be distilled, and to the use of compounds of the general formula (I) R 1_ CHO as lubricants in liquid ring pumps and to liquid ring pumps comprising or consisting of the absorption liquids according to the invention as ring liquid.
