Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 57-50-1, Name is Sucrose, molecular formula is C12H22O11, belongs to dioxoles compound, is a common compound. In a patnet, author is Bondar, VI, once mentioned the new application about 57-50-1, Category: dioxoles.
Sorption of gases and vapors in an amorphous glassy perfluorodioxole copolymer
Gas and vapor sorption properties of a random copolymer of 87 mol % 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole and 13% tetrafluoroethylene (AF2400) are reported. Using both pressure decay and inverse gas chromatography (IGC) methods, a wide range of solutes was studied: He, Nz, Oz, CO2, C-1-C-13 n-alkanes, CF4, C2F6, C6F6, and C6F5CF3. These solutes have critical temperatures ranging from 5 to 677 K. AF2400 has very large solubility coefficients, S, relative to other glassy and rubbery polymers. Only poly(1-trimethylsilyl-1-propyne), the most permeable polymer known, exhibits higher solubility coefficients. The large solubility coefficients in AF2400 are mainly due to high Henry’s law solubility coefficients. Fluorocarbon solutes exhibit higher solubility than their hydrocarbon analogues. A novel linear correlation between the logarithm of S and T-c(2), where T-c is the solute critical temperature, was observed. On the basis of IGC results, the microcavity size in this perfluoropolymer is larger than in conventional hydrocarbon-based glassy polymers.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 57-50-1. The above is the message from the blog manager. Category: dioxoles.
