Each saturated hydrocarbon is formed together with several unsaturated compounds containing the same number of carbon atoms, such as decane and isomers of decene.
The five other chapters in Volume 1 cover transition metal-catalyzed borylation of C-X and C-H bonds; metalloborylation reactions of unsaturated compounds; recent advances in the Suzuki-Miyaura cross-coupling reaction; rhodium- and palladium-catalyzed asymmetric conjugate additions of organoboronic acids; and recent advances in Chan-Lam coupling reactions.
We have evaluated some commonly used HPLC stationary phases to determine the best choice for maximizing selectivity for unsaturated compounds. We used analyses of steroids, a diverse class of pharmaceuticals that share a common fused hydrocarbon ring structure, and simple isocratic methods, to compare stationary phases.
The Allure[TM] Biphenyl stationary phase employs this mechanism in retaining and resolving unsaturated compounds.
Amosorb is based on patented organic unsaturated compounds that reportedly do not interfere with taste.
Williams has also separated unsaturated compounds from saturated ones by adding silver nitrate to the stationary phase.
PPG Industries has been granted a patent for a coating composition comprised of a continuous phase comprised of water and a dispersed phase comprised of a microgel having a mean particle size of greater than 50 nanometers to 900 nanometers and formed from reactants comprised of no more than 5% by weight, based on the total weight of the reactants, of a multi-ethylenically unsaturated compound, and a plurality of monoethylenically unsaturated compounds selected so as to provide a copolymer having a calculated Tg of greater than 100[degrees] C and comprised of a cycloaliphatic (meth)acrylate.
The compositions give good solvent- and water-resistance, are waterborne- and solventborne-modified polyolefin compositions containing unsaturated pendant groups, such as reaction product of functionalized polyolefins with ethylenically unsaturated compounds having functional groups reactive with functional groups of polyolefins, and also contain photoinitiator and optionally, other ethylenically unsaturated crosslinking agents, for UV and EB curing.
reaction product of functionalized polyolefins with ethylencially unsaturated compounds having functional groups reactions with functional groups of polyolefins, and also contain photoinitiator and optionally, other ethylencially unsaturated crosslinkng agents for UV or EB curing.
