Hydrogenation of polystyrene in CO2-expanded liquids: The effect of catalyst composition on deactivation
TL;DR: In this article, the effect of catalyst composition on the hydrogenation of polystyrene dissolved in carbon dioxide-expanded decahydronaphthalene (CO 2 -DHN) was studied using a slurry reactor at 150°C.
Journal ArticleDOI
Alkylation of benzene with propene over HBeta zeolites near supercritical conditions
TL;DR: In this article, the alkylation of benzene with propene to produce cumene over HBeta zeolites was carried out near supercritical conditions, where the reaction conditions were determined with considering the changes in the critical properties of reacting mixture along with the reaction extent.
Journal ArticleDOI
Kinetics of the Homogeneous Catalytic Hydrogenation of Olefins in Supercritical Carbon Dioxide Using a Fluoroacrylate Copolymer Grafted Rhodium Catalyst
TL;DR: In this article, the authors investigated the hydrogenation of 1-octene and cyclohexene using a fluoroacrylate copolymer grafted rhodium catalyst in supercritical carbon dioxide (scCO2) at temperatures between 50 and 120 °C and pressures ranging from 172 to 241 bar.

Polyethylene glycol radical-initiated benzylic C–H bond oxygenation in compressed carbon dioxide
Jinquan Wang,Liang-Nian He +1 more
TL;DR: The PEG radical originating from the thermal/oxidative degradation of PEG in dense CO2 was successfully applied to the oxygenation of benzylic hydrocarbons under organic solvent-free conditions as discussed by the authors.

Aqueous Sonogashira coupling of aryl halides with 1-alkynes under mild conditions: use of surfactants in cross-coupling reactions
TL;DR: Aqueous Sonogashira coupling between lipophilic terminal alkynes and aryl bromides or iodides gave moderate to high yields at 40 °C using readily available and inexpensive surfactants such as SDS and CTAB.
