Abstract
A method is described for the removal of stabilising ethanol from reag ent-grade chloroform (CHCl3) which is quicker, safer, and as effective and reliable as the standard method described in Jenkinson and Powlso n (1976). The proposed method foregoes the use of concentrated acid an d distillation and involves shaking CHCl3 with distilled water followe d by drying the final chloroform phase over anhydrous calcium chloride (CaCl2). Both methods yielded CHCl3 containing residual ethanol of le ss than 0.001% w/w.
