Purification Methods

If IR is free of OH bands then fractionally distil it; otherwise dilute the thio-ester with dry Et2O, wash with 5% KOH and H2O, dry over MgSO4 and fractionate it through an efficient column [Hauptschein et al. J Am Chem Soc 74 4005 1952]. [Beilstein 2 IV 567.] Powerful obnoxious odour.
