FIELD: separation.
SUBSTANCE: group of inventions relates to a device and a method for separating a mixture containing at least one thermolabile substance, and can be used for continuous purification of high-boiling thermolabile compounds from more volatile impurities. Device is a column apparatus, including mass-exchange, evaporation and cooling sections arranged in series one after another. Evaporation section is a vertically oriented gravity film evaporator with a fixed residence time of the thermolabile mixture in the evaporator zone.
EFFECT: obtaining separation products containing high-boiling thermolabile substances with residual content of volatile substances of not more than 100 ppm and low change in initial color.
