Propenylamines and methods of making and using same

A dielectric fluid (i.e., dielectric composition) that includes a perfluorinated 1-alkoxypropene compound represented by the following general Formula (I): RO&#x2014;CF&#x2550;CFCFwherein Ris CF&#x2014; or CFCF&#x2014;. Such dielectric fluids may be useful in various electrical devices.

Perfluorinated 1-alkoxypropenes in dielectric fluids and electrical devices

A composition includes a perfluorinated propenylamine represented by the following general formula (1): Each occurrence of Rf1 and Rf2 is: (i) independently a linear or branched perfluoroalkyl group having 1-8 carbon atoms and optionally comprises one or more catenated heteroatoms; or (ii) bonded together to form a ring structure having 4-8 carbon atoms and that optionally comprises one or more catenated heteroatoms. At least 60 wt. % of the perfluorinated propenylamine is in the form of the E isomer, based on the total weight of the perfluorinated propenylamine in the composition. 

A working fluid that includes a fluorinated olefin compound represented by the following general formula (I): 

Fluorinated olefins as working fluids and methods of using same

A working fluid that includes a fluorinated olefin compound represented by the following general formula (I). In some embodiments, an apparatus for heat transfer is provided. The apparatus includes a device and a mechanism for transferring heat to or from the device. In some embodiments, a fire extinguishing composition is provided. In some embodiments, an apparatus for converting thermal energy into mechanical energy in a Rankine cycle is provided.

Compositions are provided that include blends that consist essentially of 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane, trans-1,2-dichloroethylene, and a third component. The third component is selected from methanol, ethanol, isopropanol, t-butanol, and 1-propanol. The blends form ternary azeotropes. Provided compositions can be useful for cleaning electronic parts, as coating solvent components, as heat transfer fluids, and as lubricants.
