• Resumen

  • A procedure to purify air-sensitive liquids with high boiling points is proposed. Attempts to purify those compounds in a conventional short-path distillation apparatus were unsuccessful. The heat required for the vapors to overcome the relatively large vertical distance before reaching the condenser promotes their decomposition. A horizontal distilling apparatus that avoids extreme refluxing and can efficiently separate the fractions of a mixture was designed to purify these kinds of substances.
