Estimation of hydrocarbon solubilities in hydrofluorocarbons

Tropospheric Oxidation of 1H-Heptafluorocyclopentene (cyc-CF2CF2CF2CF═CH−) with OH Radicals: Reaction Mechanism, Kinetics, and Global Warming Potentials

“…Additionally, it is reported that an azeotropic mixture of cyc-CF 2 CF 2 CF 2 CHFCH 2 with C 3 H 7 Br, trans -CHClCHCl, and CH 2 Cl 2 can be used in various applications such as foam-blowing agent, solvent in refrigeration flushing, oxygen system cleaning, paints, adhesives and lubricants, etc . An analogous compound, trans -cyc-CF 2 CF 2 CF 2 CHFCHF ( trans -1,1,2,2,3,3,4,5-octafluorocyclopentane), has also been considered as solvent . Similarly, cyc-CF 2 CF 2 CF 2 CHCH– has been developed as a useful detergent. , The attractive properties of HFOs give us hope of their worth consideration for improvement in the environmental performances of air conditioning, refrigeration systems, and other applications.…”

Poly(isobutylene) Nanoparticles via Cationic Polymerization in Nonaqueous Emulsions

“…Furthermore, the molecular weight values are in agreement with the only other reported use of nonaqueous, fluorous emulsion polymerization of IB by Bachman et al Given the similarities between the molecular weights produced in the three different emulsion systems, the initial assumption of unfavorable side reactions seemed unlikely to be the sole determining factor on the produced molecular weight. Rather, we attribute this phenomenon to the partial solubility of alkanes ( δ n ‐hexane = 7.3 and δ n ‐pentane = 7.0) in perfluoroalkanes ( δ PFH = 5.6 and δ n ‐perfluoropentane = 5.5), leading to a shift in the “real” composition of the DCM/alkane mixture in the emulsion droplet . Additionally, the use of shorter or branched alkanes or perfluoroalkanes as a continuous phase with lower melting points, respectively, is known to increase the miscibility of the two solvents …”

From Simple Alkenes and CO2 to Fluorinated Carboxylic Acids: Computational Studies and Predictions

“…[19][20][21] Methods for synthesizing fluorinated carboxylic acids are relatively scarce and usually require precious metals or harsh reaction conditions. [22][23][24][25][26][27] Therefore, new synthetic strategies leading to the preparation of these compounds will be soon needed.…”

“…On the other hand, the carboxylic acid moiety is a widespread and versatile functional group that can be employed in the preparation of biologically active molecules or as starting point for further functionalization in drug design [19–21] . Methods for synthesizing fluorinated carboxylic acids are relatively scarce and usually require precious metals or harsh reaction conditions [22–27] . Therefore, new synthetic strategies leading to the preparation of these compounds will be soon needed.…”
