Claim 1
Independent Claim
114 words
A PROCESS FOR TREATING POLYPHENYLS WHICH COMPRISES PASSING POLYPHENYLS CONTAINING FROM 2 TO 8 PHENYL GROUPS OVER A DUAL FUNCTION CATALYST SYSTEM IN AN ATMOSPHERE OF HYDROGEN AT 400-650*C. AND A PRESSURE RANGE OF FROM ATMOSPHERIC PRESSURE TO ABOUT 50 P.S.I., SAID DUAL FUNCTION CATALYST SYSTEM CONSISTING OF A METAL COMPONENT TAKEN FROM THE GROUP CONSISTING OF IRON, COBALT, NICKLE, PLATINUM, OXIDES OF SAID METALS AND COMPLEXES OF SAID METALS AND SAID OXIDES WITH ONE ANOTHER, DEPOSITED ON AN ACIDIC SUPPORT, FROM 0.1 % TO 50% BY WEIGHT OF SAID CATALYST SYSTEM BEING SAID METAL COMPONENT, THE CONTACT TIME OF SAID POLYPHENYL WITH THE DUAL FUNCTION CATALYST SYSTEM RANGING FROM 0.1 TO 20 SECONDS.
