Recycling Solvent Mixtures of Ethyl Acetate and Hexanes
Timothy J. Wilkinson
Wheaton College, Chemistry Department, Wheaton, IL 60187

December 1998
Vol. 75 No. 12
p. 1640
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 Rf vs percent composite graph. The mixture is then diluted with the appropriate solvent to achieve the desired composition.
