    摘要： A method for producing a tetrafluoroolefin, such as 2,3,3,3-tetrafluoropropene (HFO-1234yf), comprises contacting 1,1,1,2-tetrachloro-2-fluoropropane (HCFC-241bb) with or without a catalyst under conditions effective to convert the 1,1,1,2-tetrachloro-2-fluoropropane (HCFC-241bb) to the tetrafluoroolefin, optionally, via an intermediate. The conversion may be a one-step fluorination or a two-step fluorination and dehydrochlorination process. The 1,1,1,2-tetrachloro-2-fluoropropane (HCFC-241bb) may also be obtained by dehydrochlorinating 1,2,3-trichloropropane (HCC-260da) to form 2,3-dichloropropene (HCO-1250xf); fluorinating 2,3-dichloropropene (HCO-1250xf) to form 1,2-dichloro-2-fluoropropane (HCFC-261bb); and chlorinating 1,2-dichloro-2-fluoropropane (HCFC-261bb) to form 1,1,1,2-tetrachloro-2-fluoropropane (HCFC-241bb).

    摘要： The present invention provides methods for selecting refrigerant and lubricant combinations for use in heat transfer cycle systems and provides methods for operating said heat transfer systems. More particularly, the invention provides methods to select lubricant and refrigerant combinations for a heat transfer cycle system wherein at the lower temperatures of the heat transfer cycle the refrigerant and lubricant are miscible and at the upper temperatures of the heat transfer cycle the refrigerant and lubricant are phase separated and such that the density phase inversion temperature of the combination is below the upper operating temperature of the heat transfer cycle.
