Process for reacting ccl4 with caf2 in a fluid bed, and the fluid bed therefor

Claim 2

A COMPOSITION, ADAPTED FOR USE AS A FLUID BED IN THE VAPOR PHASE REACTION OF CCL4 WITH CAF2 TO FORM CCL3F, WHICH IS AN INTIMATE MIXTURE OF DISCRETE SOLID PARTICLES CONSISTING ESSENTIALLY OF BETWEEN 9% AND 50% BY WEIGHT OF CAF2 PARTICLES HAVING A SIZE SUCH THAT THEY ALL PASS THROUGH A 325 MESH SCREEN BUT AT LEAST 55% OF THEM ARE AT LEAST AS LARGE AS 10 MICRONS, FROM ABOUT 2% TO ABOUT 20% BY WEIGHT OF CARBON PARTICLES HAVING A SIZE SMALLER THAN 3 MICRONS AND AN AVERAGE SIZE NOT LARGER THAN ABOUT 1 MICRON, AND FROM 89% TO ABOUT 30% BY WEIGHT OF DILUENT PARTICLES HAVING A SIZE SUCH THAT SUBSTANTIALLY ALL OF THEM PASS THROUGH A 100 MESH SCREEN AND ARE RETAINED ON A 325 MESH SCREEN, SUCH DILUENT PARTICLES BEING PARTICLES OF AT LEAST ONE MEMBER OF THE GROUP CONSISTING OF CAF2, SIO2 AND AL2O3.

Claim 3

THE PROCESS FOR PRODUCING CCL3F FROM CCL4 WHICH COMPRISES PASSING GASEOUS CCL4 AT A SUPERFICIAL LINEAR VELOCITY OF FROM 0.1 TO 0.3 FOOT PER SECOND UPWARD THROUGH A FLUID BED MAINTAINED AT A TEMPERATURE OF FROM ABOUT 450* C. TO ABOUT 550* C. AND RECOVERING CCL3F FROM THE GASEOUS REACTIONPRODUCTS, SAID FLUID BED BEING AN INTIMATE MIXTURE OF DISCRETE SOLID PARTICLES CONSISTING ESSENTIALLY OF BETWEEN 9% AND 50% BY WEIGHT OF CAF2 PARTICLES HAVING A SIZE SUCH THAT THEY ALL PASS THROUGH A 325 MESH SCREEN BUT AT LEAST 55% OF THEM ARE AT LEAST AS LARGE AS 10 MICRONS, FROM ABOUT 2% OT ABOUT 20% BY WIEGHT OF CARBON PARTICLES HAVING A SIZE SMALLER THAN 3 MICRONS AND AN AVERAGE SIZE NOT LARGER THAN ABOUT 1 MICRON, AND FROM 89% TO ABOUT 30% BY WEIGHT OF DILUENT PARTICLES HAVING A SIZE SUCH THAT SUBNSTANTIALLY ALL OF THEM PASS THROUGH A 100 MESH SCREEN AND ARE RETAINED ON A 325 MESH SCREEN, SUCH DILUENT PARTICLES BEING PARTICLES OF AT LEAST ONE MEMBER OF THE GROUP CONSISTING OF CAF2, SIO2 AND AL2O3.

Claim 4

THE PROCESS FOR PRODUCING CCL3F FROM CCL4 WHICH COMPRISES PASSING GASEOUS CCL4 AT A SUPERFICIAL LINEAR VELOCITY OF FROM 0.1 TO 0.3 FOOT PER SECOND UPWARD THROUGH A FLUID BED MAINTAINED AT A TEMPERATURE OF FROM ABOUT 450* C. TO ABOUT 550* C. AND RECOVERING CCL3F FROM THE GASEOUS REACTIONPRODUCTS, SAID FLUID BED BEING AN INTIMATE MIXTURE OF DISCRETE SOLID PARTICLES CONSISTING ESSENTIALLY OF BETWEEN 9% AND 50% BY WEIGHT OF CAF2 PARTICLES HAVING A SIZE SUCH THAT THEY ALL PASS THROUGH A 325 MESH SCREEN BUT AT LEAST 55% OF THEM ARE AT LEAST AS LARGE AS 10 MICRONS, FROM ABOUT 2% OT ABOUT 20% BY WIEGHT OF CARBON PARTICLES HAVING A SIZE SMALLER THAN 3 MICRONS AND AN AVERAGE SIZE NOT LARGER THAN ABOUT 1 MICRON, AND FROM 89% TO ABOUT 30% BY WEIGHT OF DILUENT PARTICLES HAVING A SIZE SUCH THAT SUBNSTANTIALLY ALL OF THEM PASS THROUGH A 100 MESH SCREEN AND ARE RETAINED ON A 325 MESH SCREEN, SUCH DILUENT PARTICLES BEING PARTICLES OF AT LEAST ONE MEMBER OF THE GROUP CONSISTING OF CAF2, SIO2 AND AL2O3.
