Aldrich falling-film distillation heads

The material is in contact with the heated center finger for only a brief period of time, avoiding decomposition by long-term exposure to heat. This system can be used at atmospheric or reduced pressure. Fig. 1 shows a typical distillation set-up.

 

Falling Film Technique (See Fig. 1)

  • Flask A is filled with the solvent desiredand heated to reflux. The boiling solvent vapor maintains a constant temperature at the center finger. The temperature is the boiling point of the solvent.
  • The material to be distilled is placed in theaddition funnel and allowed to drip slowlyonto the heated center finger. The volatilized material will condense on the outer air- cooled wall and collect in Flask B. The high boiling material will remain on the center finger and flow down the spiral into Flask C.
  • Any pressure-equalizing funnel, standard condenser, and flasks can be used.
