WebJun 22, 2024 · Kugelrohr Distillation. Separation of small amounts of compounds with close boiling points is difficult in a fractional distillation setup and can alternatively be performed via Kugelrohr Distillation. The setup is shown in the image above. Typically high boiling compounds are used and vacuum is applied. To perform a Kugelrohr Distillation: Compounds with a boiling point lower than 150 °C typically are distilled at ambient pressure. For samples with high boiling points, short-path distillation apparatus is commonly employed.This technique is amply illustrated in Organic Synthesis.
