Abstract

1533303 Removing water by crystallisation BAYER AG 25 June 1976 [2 July 1975] 26510/76 Heading BIG A process for removing water from a watercontaining organic liquid comprising a polymerisable unsaturated hydrocarbon with isolated or conjugated double and/or triple bonds comprises cooling the liquid to a temperature below 0‹C, preferably -5‹ to -30‹C, filtering off the ice which is formed and recovering the dried organic liquid.
