  • Patent number: 11932589
    Abstract: A hydrofluoroolefin compound is represented by the following general formula (I): where RF1 is a hydrogen atom or CH3, and (iii) RF1 is a linear or branched perfluorinated alkyl group having 1 to 10 carbon atoms and optionally including one or more catenated heteroatoms; and RF2 is a fluorine atom or a linear or branched perfluorinated alkyl group having 1 to 8 carbon atoms and optionally including one or more catenated heteroatoms; with the proviso that when RF2 is a fluorine atom, then RF1 includes at least 2 carbon atoms; or (iv) RF1 and RF2 are bonded together to form a ring structure having 4 to 8 carbon atoms and optionally including one or more catenated heteroatoms.

  • Patent number: 10934247
    Abstract: The present invention relates to an unsaturated fluorinated ether or amine compound of formula (I) with low global warming potential and method of making the compound (I), where RH1 is and RH2 are independently selected from H or CH3, wherein when RH1 is CH3 then RH2 is H and when RH2 is CH3, then RH1 is H; X is O or N and when X is O, then n is 1 and Rf is a linear or branched perfluorinated alkyl group comprising 1-10 carbon atoms and optionally comprising at least one catenated O or N atom; X is N, then n is 2 and (i) each Rf is independently selected from a linear or branched perfluorinated alkyl group comprising 1-8 carbon atoms and optionally comprising at least one catenated O or N atom, or (ii) the two Rf's are bonded together to form a ring structure optionally comprising at least one catenated O or N atom, wherein the ring of the ring structure consists of 5-7 atoms, no more than 10 carbon atoms, and is perfluorinated.
