BY sorption on ion exchange resins1–3 it is possible to separate some coumarins in dilute solution. A column of the strongly basic anion exchange resin, ‘Amberlite IRA–400’ (−40, +60 mesh; Rohm and Haas Co.), in the chloride form (bed length, 50 cm; bed volume, 25.8 c.c.) has been used for this purpose.
