PURPOSE: To efficiently remove metal halides from liquid org. waterimmiscible substances contg. the metal halides by treating the liquid org. water-immiscible substances with a water-contg. anionexchanger in the OH form. n CONSTITUTION: The liquid org. water-immiscible substances contg. the metal halides are treated with the water-contg. anion-exchanger in the OH form, by which the metal halides are adsorbed and removed from the liquid org. water-immiscible substances. The more specific examples of the liquid org. water-immiscible substances include arom. hydrocarbons, such as benzene, toluene and xylene, chlorinated hydrocarbons, such as chlorobenzene and dichlorobenzene. The moisture content of the anion-exchanger is adequately 50 to 70 wt.%. The process of passing liquid org. substances which do not mix with the water to be removed of the metal halides through the anion- exchanger arranged in the apparatus is adequate as this process. n COPYRIGHT: (C)1989,JPO |
