High impact information on Cyclic methylethylene carbonate

• Asymmetric catalysis with CO2: direct synthesis of optically active propylene carbonate from racemic epoxides [1].
• Similarly, pressure and propylene carbonate induced the formation of irreversibly denatured forms of aged butyrylcholinesterase [2].
• Electrophoretic mobilities of large organic ions in nonaqueous solvents: determination by capillary electrophoresis in propylene carbonate, N,N-dimethylformamide, N,N,-dimethylacetamide, acetonitrile and methanol [3].
• New chiral catalyst systems were developed for the reaction of carbon dioxide with propylene oxide (PO) at atmospheric pressure to generate enantiomerically enriched propylene carbonate (PC) [4].
• The synthesis of propylene carbonate from propylene oxide and carbon dioxide under supercritical conditions in the presence of 1-octyl-3-methylimidazolium tetrafluoroborate was achieved in nearly 100% yield and 100% selectivity within 5 minutes, whose TOF value is 77 times larger than those so far reported [5].

Anatomical context of Cyclic methylethylene carbonate

• Enprostil (methyl 7-[(1R*,2R*,3R*)-3-hydroxy-2-[(E)-(3R*)-3-hydroxy-4-phenoxy-1-butenyl]- 5-oxocyclopentyl]-4,5-heptadienoate), a gastric acid secretion inhibitor and potent anti-ulcer drug, is formulated as a propylene carbonate solution which is filled into soft elastic gelatin capsules [6].
• Engineering of vascular grafts with genetically modified bone marrow mesenchymal stem cells on poly (propylene carbonate) graft [7].

Associations of Cyclic methylethylene carbonate with other chemical compounds

• Less pronounced, the increasing polarity in 1,4-dioxane/propylene carbonate mixtures affected the fluorescence yield much less [8].
• The microstructure of aggregates formed by sodium dodecyl sulfate (SDS) and 1-pentanol in mixtures of water and a polar aprotic solvent (propylene carbonate, PC) was investigated by means of pulsed gradient spin-echo NMR, dynamic light scattering, viscosity, and conductivity measurements [9].
• We investigated the photochemistry of MC dissolved as a hydrophobic ion pair with a hexadecyltrioctadecylammonium cation in cyclohexane, trimethylpentane and toluene as well as in propylene carbonate, CH3CN, C2H5OH and D2O [10].
• The dynamical screening length xi(h) in semidilute to highly concentrated polymer solutions of poly(methyl methacrylate) in propylene carbonate has been examined using photon correlation spectroscopy and pulsed field gradient nuclear magnetic resonance [11].
• The interaction of calix[3]thieno[1]pyrrole, 1, and halide and dihydrogen phosphate anions in a variety of solvents (acetonitrile, propylene carbonate, N,N-dimethylformamide, and dimethyl sulfoxide) has been investigated through 1H NMR, conductance measurements, and titration calorimetry [12].

Gene context of Cyclic methylethylene carbonate

• It was discovered that the optimal catalyst for copolymer selectivity vs the monomeric propylene carbonate was one that contained a salen ligand with an electron-withdrawing phenylene backbone and electron-donating tert-butyl groups in the phenolate rings [13].

Analytical, diagnostic and therapeutic context of Cyclic methylethylene carbonate

• In a ZnO quantum-dot assembly permeated with a propylene carbonate electrolyte solution, there is a strong overlap between these two regimes [14].
• Propylene carbonate as a nonaqueous solvent for capillary electrophoresis: mobility and ionization constant of aliphatic amines [15].
• Determination of propylene carbonate in pharmaceutical formulations using liquid chromatography [16].
• A stability-indicating reversed-phase high-performance liquid chromatographic method using a refractive index detector is described for the determination of propylene carbonate in pharmaceutical formulations [16].
• At levels of hydration greater than 12.5% by mass, the yield of propylene carbonate was further enhanced, but at a smaller rate than that observed at lower rehydration levels, which is more indicative of an enhanced transport effect [17].
