Summary[edit]
DescriptionDistillation of dry and oxygen-free toluene.jpg |
English: Distillation of dry and oxygen-free toluene from sodium-benzophenone desiccant. Glassware are under a slight positive nitrogen pressure from the side-arm of the receiving Schlenk flask to prevent oxygen contamination. Note that this is not a closed system - the nitrogen supply is connected to an oil bubbler (not in picture) to prevent overpressure.
