    Abstract: An immersion cooling system includes a housing having an interior space; a heat-generating component disposed within the interior space; and a working fluid liquid disposed within the interior space such that the heat-generating component is in contact with the working fluid liquid. The working fluid comprises a compound having Structural Formula (IA) Each Rf1 and Rf2 is, independently, (i) a linear or branched perhalogenated acyclic alkyl group having 1-6 carbon atoms and optionally contains one or more catenated heteroatoms selected from O or N; or (ii) a perhalogenated 5-7 membered cyclic alkyl group having 3-7 carbon atoms and optionally contains one or more catenated heteroatoms selected from O or N.

    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, Cl, 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.
