Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons. 1835-49-0, formula is C8F4N2, Name is Tetrafluoroterephthalonitrile. Nitriles are found in many useful compounds. One of the most common occurrences of nitriles is in Nitrile rubber. Recommanded Product: Tetrafluoroterephthalonitrile.
Ricci, Eleonora;Benedetti, Francesco M.;Noto, Antonella;Merkel, Timothy C.;Jin, Jianyong;De Angelis, Maria Grazia research published 《 Enabling experimental characterization and prediction of ternary mixed-gas sorption in polymers: C2H6/CO2/CH4 in PIM-1》, the research content is summarized as follows. In this work, a new exptl. protocol was designed to measure sorption of ternary gas mixtures in polymer membranes for the first time. We measured the sorption isotherms of binary and ternary mixtures of C2H6, CO2, and CH4 in PIM-1, using a pressure decay apparatus, working at constant composition and variable pressure of the gas phase. The results show competitive sorption effects in all gas mixtures analyzed, affecting each species in proportion to the total sorbed concentration of the other components. It was found that the presence of C2H6 in the mixture reduces the sorption of both CH4 and CO2 to a similar extent, so that the CO2/CH4 solubility-selectivity is not markedly affected. The exptl. data were used to validate predictions of the Non-Equilibrium Lattice Fluid (NELF) model of binary and ternary sorption isotherms. The NELF model is generally in close agreement, both in the prediction of pressure and mixture composition effects, proving to be a reliable tool to assess mixed-gas sorption, even in complex scenarios.

Tetrafluoroterephthalonitrile is a hydroxyl group-containing organic chemical compound . It has been used in analytical chemistry as a reagent for the determination of peptide binding constants and disulfide bonds. Tetrafluoroterephthalonitrile binds to nucleophilic sites on proteins, such as the pim-1 protein, and can be used to transport other molecules across cell membranes. In addition, it has been used to produce polymers for use in analytical chemistry. This chemical is also able to bind with magnetic particles under constant pressure conditions, which makes it useful for optical sensor applications. , Recommanded Product: Tetrafluoroterephthalonitrile
