Catalytic Epoxidation of Limonene
The epoxidation of limonene with hidrogen peroxide was studied over zeolite Tibeta (a large pore material) and heteropoly acids on carbono and alumina supported. PW11/C was catalyst the best tested. Introduction In the last years, the increase in environmental restrictions lead to the search for new oxydant systems to replace the traditionals in order to avoid the generation of polluting efflue...
متن کاملIn situ ATR studies on the mechanism of limonene epoxidation over PW-Amberlite
Introduction PW-Amberlite is a promising catalyst for limonene epoxidation with aqueous hydrogen peroxide and acetonitrile as solvent; limonene conversion and limonene epoxide selectivity higher than 80 % and 90 %, respectively, have been reported [1,2]. The mechanistic pathway proposed for limonene epoxidation on PW-Amberlite [3], includes the interaction of H2O2 with peroxophosphotungstate sp...
متن کاملThe epoxidation of limonene over the TS-1 and Ti-SBA-15 catalysts.
Limonene belongs to a group of very important intermediates used in the production of fine chemicals. This monoterpene compound can be obtained from peels of oranges or lemon which are a (biomass) waste from the orange juice industry. Thus, limonene is a renewable, easy available and a relatively cheap compound. This work presents preliminary studies on the process of limonene epoxidation over ...
متن کاملSize-Specific Chemistry of Ag Nanostructures in Catalytic Ethylene Epoxidation
The low selectivity of heterogeneous catalysts has been one of the critical obstacles to the wider use of heterogeneous processes in the commercial production of high value chemicals. The limited selectivity is related to a number of issues, including the lack of predictive theories that guide the discovery of the optimal catalytic site, the dearth of strategies to synthesize the targeted sites...
متن کاملAnodic aluminium oxide catalytic membranes for asymmetric epoxidation.
Catechol-functionalized (salen)Mn complexes can be supported on mesoporous anodized aluminium oxide disks to yield catalytic membranes that are highly active in the enantioselective epoxidation of olefins when being deployed in a forced-through-flow reactor.
