二、短程分子蒸餾介紹
Introduction of short range molecular distillation
分子蒸餾是一種特殊的液-液分離技術，它不同于傳統蒸餾依靠沸點差分離的原理。這是一種在高真空度下利用不同物質分子運動自由程的差別，對熱敏性物質或者是高沸點物質進行蒸餾和純化的過程。主要應用在化學、醫藥、石化、香料、塑料以及油料等工業領域。
Molecular Distillation is a special liquid-liquid separation technology, which is different from traditional distillation on the difference boiling point. This is a kind of distillation in high vacuum environment, for the difference of material molecular movement free path, was carried out in the heat sensitive material or high boiling point material distillation and purification process. Short Path Distillation is mainly used in chemical, pharmaceutical, petrochemical, spices, plastics, oil and other fields.
