Abstract
Described herein is a perfluorinated aminoolefin compound of general formula (I): CFY═CXN(R)CFR' where: (a) Rand R′ are (i) independently selected from a linear or branched perfluoroalkyl group having 1-8 carbon atoms, optionally comprising at least one catenated O or N atom, or (ii) bonded together to form a perfluorinated ring structure having 4-8 ring carbon atoms, optionally comprising at least one catenated O atom; and (b) X and Y are (i) independently selected from a perfluoroalkyl group having 1-4 carbon atoms, or (ii) bonded together to form a perfluorinated ring structure having 5-6 ring carbon atoms. Such compounds may be used in heat transfer, foam blowing or immersion cooling applications, or as a working fluid in a Rankine cycle, a coating or lubricant, or as a dielectric fluid. Also disclosed herein is a method for making such compounds.
