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. The applications of the compound include solvent cleaning, electrolyte solvents or additives, heat transfer, and vapour phase soldering.
