Crystallization of adipic acid in the presence of polyorgano siloxane

Claim 1

IN THE PROCESS OF CONTINUOUSLY CRYSTALLIZING ADIPIC ACID FROM THE REACTION PRODUCT RESULTING FROM NITRIC ACID OXIDATION OF A MIXTURE OF CYCLOHEXANOL AND CYCLOHEXANONE PRODUCED BY LIQUID PHASE OXIDATION OF CYCLOHEXANE, THE STEPS COMPRISING: (A) FLOWING A STREAM OF SAID REACTION PRODUCT INTO A VACUUM ZONE WHEREIN EVAPORATION AND COOLING THEREOF OCCUR TO DEVELOP SUPERSATURATION OF THE ADIPIC ACID; (B) FLOWING THE RESULTING SUPERSATURATE SOLUTION TO A CRYSTALLIZATION ZONE WHEREIN CRYSTALS OF ADIPIC ACID FORM; (C) RECYCLING A PORTION OF SAID SOLUTION TO THE VACUUM ZONE; (D) WITHDRAWING RESULTING MAGMA CONTAINING ADIPIC ACID CRYSTALS FROM THE CRYSTALLIZATION ZONE; (E) FILTERING AND REMOVING A PORTION OF THE ADIPIC ACID CRUSTALS AND A PORTION OF THE MOTHER LIQUOR FROM THE WITHDRAWN MAGMA; (F) RECYCLING THE MAGMA FROM WHICH SAID PORTIONS OF ADIPIC ACID AND MOTHER LIQUOR HAVE BEEN REMOVED TO THE CRYSTALLIZATION ZONE; AND (G) CONTINUOUSLY ADDING AN AQUEOUS EMULSION OF A LIQUID POLYORGANO SILOXANE IN AN AMOUNT SUFFICIENT TO MAINTAN ABOUT 0.1-10 P.P.M. OF THE SILOXANE IN THE VACUUM AND CRYSTALLIZATION ZONES, SAID AQUEOUS EMULSION BEING DISSOLVABLE IN SAID MAGMA, AND SAID SILOXANE HAVING THE GENERAL FORMULA:
