    • Aspects of the present invention are directed to working fluids and their use in processes wherein the working fluids comprise compounds having the structure of formula (I): wherein R1, R2, R3, and R4 are each independently selected from the group consisting of: H, F, Cl, Br, and C1-C6 alkyl, at least C6 aryl, at least C3 cycloalkyl, and C6-C15 alkylaryl optionally substituted with at least one F, Cl, or Br, wherein formula (I) contains at least one F and at least one Cl or Br, provided that if any R is Br, then the compound does not have hydrogen. The working fluids are useful in Rankine cycle systems for efficiently converting waste heat generated from industrial processes, such as electric power generation from fuel cells, into mechanical energy or further to electric power. The working fluids of the invention are also useful in equipment employing other thermal energy conversion processes and cycles.
    • 本发明的方面涉及工作流体及其在工作流体中的用途,其中工作流体包含具有式(I)结构的化合物:其中R 1,R 2,R 3和R 4各自独立地选自:H ,F,Cl,Br和C 1 -C 6烷基,至少C 6芳基,至少C 3环烷基和任选被至少一个F,Cl或Br取代的C 6 -C 15烷芳基,其中式(I)含有至少一个 F和至少一个Cl或Br,条件是如果任何R是Br,则化合物不具有氢。 工作流体在兰金循环系统中有用,可有效地将工业过程产生的废热(如燃料电池的发电)转化为机械能或进一步电力。 本发明的工作流体也可用于采用其它热能转换过程和循环的设备中。
