    Abstract: In an embodiment, a method of producing a fluoroolefin comprises coupling 3,3-dichloro-1,1,1,2,2-pentafluoropropane (CF3—CF2—CHCl2) in a liquid phase in the presence of a catalyst to form a composition comprising 1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3CF2CH═CHCF2CF3). In another embodiment, a method of producing a fluoroolefin comprises coupling 1,1,1-trichloropentafluoropropane (CF3—CF2—CCl3) in a vapor phase in the presence of a first catalyst to form a composition comprising 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3—CF2—CCl═CCl—CF2—CF3). The method may further include forming the CF3—CF2—CCl3 in a vapor phase from CF3CF2CHmCl3-m and chlorine (Cl2). The method may further include hydrodechlorinating the 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene with hydrogen (H2) in a vapor phase in the presence of a second catalyst to form a composition comprising CF3CF2CH═CHCF2CF3 and 3-chloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3CF2CCl═CHCF2CF3).

    Abstract: A process of thermal fluid reclamation includes combining at least two recovered thermal fluids including at least two refrigerant compounds to form a consolidated thermal fluid. The consolidated thermal fluid is a blend of the at least two refrigerant compounds having a consolidated composition different from a recovered composition of at least one of the least two recovered thermal fluids. The process also includes testing the consolidated thermal fluid and validating that the consolidated thermal fluid has greater than 95 wt % organic purity. The process further includes adding at least one virgin thermal fluid or used thermal fluid to the consolidated thermal fluid to form a reconstituted thermal fluid. The process yet further includes analyzing and purifying the reconstituted thermal fluid to form a reclaimed thermal fluid. The reclaimed thermal fluid has a predetermined reclaimed thermal fluid composition different from a consolidated thermal fluid composition of the consolidated thermal fluid.
