Abstract
A BENZENE/ETHANOL (65 : 35) Soxhlet extract of air-dried high-moor peat (bitumen) has been separated into fractions by means of a column of the strongly basic anion-exchange resin ‘De-Acidite FF’ in the acetate form. The resin was converted from the chloride form in the manner described by Logie1. The effluent was collected in 2.5 gm. fractions and optical density measurements at 285 mµ were employed for the detection of the eluted fractions.
