Abstract

A method to recycle ethyl acetate-hexanes mixtures from thin-layer or column chromatography experiments is described. The procedure consists of co-distillation of the mixture followed by estimation of the composition by reference to an R_f vs percent composite graph. The mixture is then diluted with the appropriate solvent to achieve the desired composition.

  Abstract:
  Powdered cinnamon foams badly on attempted steam distillation. It has been demonstrated that preliminary iterative evacuation of the aqueous mixture allows smooth distillation of cinnamaldehyde (I).
