Adsorption of cytochrome c by succinic anhydride-modified peanut shells
A novel adsorbent based on peanut shells modified with glutaraldehyde and succinic anhydride was prepared. Factors affecting the adsorption capacity, such as the pH, temperature, adsorption time, initial cytochrome c (cyt c) concentration and NaCl ionic strength, were extensively investigated. The results showed that the maximum adsorption capacity of the modified peanut shells (MPSs) was 432.6...
متن کاملParallel kinetic resolutions of monosubstituted succinic anhydrides catalyzed by a modified cinchona alkaloid.
Efficient kinetic resolution processes continue to play a critical role in asymmetric synthesis.1 Using two chiral reagents to effect two parallel running enantioselective resolution reactions, Vedejs and co-workers demonstrated that, through minimizing a buildup of the less reactive enantiomer by simultaneously consuming both enantiomers of the racemic starting material, the two resolution rea...
متن کاملPreparation and structure of Octenyl succinic anhydride modified waxy maize starch, microporous starch and maltodextrin
Octenyl succinic anhydride (OSA) modified starch is widely used in emulsion and encapsulation applications. The functionality of OS starch depends on its molecular structure. A systematic study was performed to investigate the reaction of OSA with granular waxy maize (WM) starch, microporous WM starch and soluble maltodextrin. OS starches were prepared in an aqueous slurry system, and the degre...
متن کاملComputational study on kinetics and mechanisms of unimolecular decomposition of succinic acid and its anhydride.
The mechanisms and kinetics of unimolecular decomposition of succinic acid and its anhydride have been studied at the G2M(CC2) and microcanonical RRKM levels of theory. It was shown that the ZsgsZ conformer of succinic acid, with the Z-acid form and the gauche conformation around the central C-C bond, is its most stable conformer, whereas the lowest energy conformer with the E-acid form, ECGsZ,...
متن کاملHydrophobicities of poly(e-caprolactone) oligomers functionalized with different succinic anhydrides
Different succinic anhydrides were used for modification of hydrophobicities of linear and star-shaped poly (e-caprolactone) oligomers with different molecular weights. Hydroxylterminated poly(e-caprolactone) oligomers were acid-functionalized either with succinic anhydride (SAH) or with alkenylsuccinic anhydrides (ASAs) containing 8 or 18 carbons in their alkenyl chains. Hydrophobicities of th...
