About 80% or greater of the hydrochlorofluorocarbon mixture is the fluoroolefin. The dehydrohalogenation product also includes a caustic agent and a solvent. In some embodiments, the dehydrohalogenation product is free of any catalyst, including any phase transfer catalyst.
Provided is a compression molding composition, in which an emulsion-polymerized polytetrafluoroethylene (PTFE) and a filler are mixed in a substantially uniform manner without generating an aggregate, and the used PTFE is not particularly limited. The compression molding composition includes emulsion-polymerized polytetrafluoroethylene, a heat-processible fluoropolymer, and a filler, the melt flow rate (MFR) of the heat-processible fluoropolymer is from 0.01 to 100 g/10 min, and the content of the heat-processible fluoropolymer is from 1 to 40 mass % relative to the total of the emulsion-polymerized polytetrafluoroethylene and the heat-processible fluoropolymer.
Refrigerant compositions including 2,3,3,3-tetrafluoropropene (HFO-1234yf) and at least one of ethane (R-170) or propane (R-290) which exhibit near-azeotropic or azeotrope-like behavior. The refrigerant compositions exhibit a low global warming potential (GWP) and are non-ozone depleting. The refrigerant compositions are useful as a heating or cooling fluids in a variety of heating or cooling systems including heat pumps and other heating and cooling loops, in, for example, the automotive industry.
