- Cobalt/N-Hydroxyphthalimide(NHPI)-Catalyzed Aerobic Oxidation of Hydrocarbons with Ionic Liquid Additive
-
A highly efficient and solvent-free system of cobalt/NHPI-catalyzed aerobic oxidation of hydrocarbons was developed using imidazolium-based ionic liquid (IL) as an additive. These amphipathic ILs were found self-assemble at the interface between the organic hydrocarbons and the aqueous phase of catalyst combination (Co/NHPI), with forming a solution of reversed multilamellar vesicles for catalysis. The initial reaction rate was influenced by both the composition of microdomains and the structure of IL launched. Consequently, a proper water content (χH2O) of wet IL was requisite to reach the optimum reactivity. Besides, the interfacial boundary between aqueous and organic phase composed by C2-alkylated imidazolium ILs, such as [bdmim]SbF6 and [C12dmim]SbF6, not only has ternary aggregates (hydrocarbons/IL/H2O) of higher stability but renders O2 a faster diffusion rate and higher concentration, thereby offering a high reactivity of the protocol towards hydrocarbon oxidation.

- PHENYLENE OXO-DIESTER PLASTICIZERS AND METHODS OF MAKING
-
A process for making non-phthalate, 1,2-phenylene oxo-diester plasticizers for polymer compositions, by selectively hydrogenating naphthalene to form a partially hydrogenated naphthalene, oxygenating said partially hydrogenated naphthalene to form phenylene diacids, and esterifying said phenylene diacids with oxo-alcohols to form 1,2-phenylene oxo-diesters. Also a process for making phenylene oxo-diester plasticizers by selectively brominating xylenes to form bisbromomethylbenzene, catalytic carboalkoxylation of the bromo-compound to form phenylene diacetate, followed by transesterification to form the phenylene oxo-diester.
