Abstract (en)

[origin: US2013240345A1] A process for producing high-purity liquids, in particular liquid chemicals, by distillation, includes the steps of: providing a liquid to be purified from a storage vessel in a sample container arranged in a sample chamber, heating and evaporating the uppermost layers of the liquid to be purified, condensing the sample vapor produced of the liquid to be purified in a condensation device outside the sample chamber, and collecting the distillate in a collecting container. The collecting container being connectable to the storage vessel via a return line for the non-condensed sample vapor and forming a space that is closed off from the surroundings between the space above the liquid surface of the liquid to be purified in the sample chamber and the storage vessel.
