    Abstract: A process for transferring heat including providing an article and contacting the article with a heat transfer media. The heat transfer media includes a composition formed by the process of, contacting a compound of formula (1), RfCH═CHF, with a fluorinated ethylene compound of formula (2), CX1X2═CX3X4 in the presence of a Lewis acid catalyst. In the compound of formula (1) Rf is a C1-C10 perfluorinated alkyl group. In the compound of formula (2) X1, X2, X3, and X4 are each independently H, Cl, or F and at least one of X1, X2, X3, and X4 is F. The resulting composition comprises a compound of formula (3), RfCF3(CX5X6CX7X8)nCH═CHCX9X10CX11X12F. In the compound of formula (3), X5, X6, X7, X8, X9, X10, X11, and X12 are each independently H, Cl, or F, and n is an integer of 0 or 1.

    Abstract: The present invention relates to a process and apparatus for quantifying solid residue on a sample. The process includes using a solid substrate and an aerosolizing device, adding a solid material to the aerosolizing device, forming a particle cloud of solid particles, wherein at least 1% of the mass concentration of solid particles have a mass median aerodynamic particle diameter up to about 10 μm, thus applying the solid particles to the solid substrate(s) to form treated substrate(s), maintaining at a temperature of from about 30 to about 120° C. for at least a portion of the process, and removing a portion of solid particles from the treated substrate(s), and analyzing said at least one sample. The present invention further comprises an apparatus for applying solid particles to a substrate. The process can be used, for example, to analyze the dirt pickup resistance of a solid sample.
