摘要： This invention relates to the use of ion exchange resins having metal-exchanged thiol functional groups in removing iodide impurities from carboxylic acids and/or carboxylic acid anhydrides. More particularly, this invention provides a process for removing iodide impurities from liquid carboxylic acids and/or carboxylic acid anhydrides using ion exchange resins in which thiol functional groups have been exchanged with silver, palladium or mercury.

摘要： A process for the recovery of silicone oil and chlorobenzenes from a mixture containing silicone oil, chlorobenzenes, and polychlorinated biphenyls comprising:(a) introducing the mixture into a distillation zone at a temperature and a pressure which will cause the chlorobenzenes to flash overhead and the mixture of silicone oil and polychlorinated biphenyls to pass to the bottom of the zone; and(b) removing the bottoms from step (a), cooling same, and passing the bottoms through at least one bed of activated carbon, which is an adsorbent for polychlorinated biphenyls.
