Title: NITROGEN AND DIOXOLANE-CONTAINING HYDROFLUOROETHERS AND METHODS OF USING THE SAME
Abstract:
Described herein is dioxolane-containing compound of formula (I): wherein (i) Rf1 and Rf2 are independently linear or branched perfluoroalkyi groups having with 1-8 carbon atoms and optionally comprise at least one catenated heteroatom, or (ii) Rf1 and Rf2 are bonded together to form a ring structure having 4-6 carbon atoms and optionally comprise one or more catenated heteroatoms; Rf2 is a linear or branched perfluoroalkyi groups having with 1 -3 carbon atoms; and R4 and R5 are independently selected from H, F, CI, a linear or branched alkyl group having 1 -3 carbon atoms, optionally wherein the alkyl group comprises at least one of: fluorine, chlorine, a hydroxyl group, or a catenated heteroatom; for use in cleaning compositions, as an electrolyte solvent, as a heat transfer fluid, or a vapor phase soldering fluid. There is also provided a method of making the dioxolane-containing compound, comprising: contacting a 1,2-diol compound with a fluorinated ethylenically unsaturated compound in the presence of a base.
