Abstract

1463324 Recovering ethylene glycol; reverse osmosis HOECHST AG 9 Oct 1974 [9 Oct 1973] 43682/74 Heading C2C [Also in Division B1] Ethylene glycol is recovered, from water containing it together with salts, by subjecting the water to reverse osmosis, through a semipermeable membrane, by means of a pressure of 30-100 atmos. g. and removing the fraction containing the greatest part of the ethylene glycol.
