Method and apparatus for short-path distillation |
摘要 |
In a method and apparatus for short-path, high-vacuum distillation from a liquid on plate-like evaporating surfaces from which distillable fractions evaporate and precipitate onto condensation surfaces a short distance away, the liquid is placed upon the evaporating surfaces at a temperature such that the energy required for its evaporation is taken, at least in part, from the still-unevaporated fraction of the liquid.
