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 Ris and Rare independently selected from H or CH, wherein when Ris CHthen Ris H and when Ris CH, then Ris H; X is O or N and when X is O, then n is 1 and Ris 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 Ris 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 R'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.
