METHOD FOR THE EPOXIDATION OF AN OLEFIN WITH HYDROGEN PEROXIDE
Epoxidation of an olefin is carried out by continuously reacting the olefin with hydrogen peroxide in the presence of a homogeneous epoxidation catalyst in a reaction mixture comprising an aqueous liquid phase and an organic liquid phase, using a loop reactor with mixing of the liquid phases. The loop reactor comprises a measuring section in which the liquid phases are temporarily separated, at least one pH electrode is arranged in the measuring section in contact with the separated aqueous phase, a pH of the separated aqueous phase is determined with the pH electrode and the pH is maintained in a predetermined range by adding acid or base to the loop reactor.
Non-precious Metal-based Hyrdosilylation Catalysts Exhibiting Improved Selectivity
Disclosed herein is the use of manganese, iron, cobalt, or nickel complexes containing tridentate pyridine di-imine ligands as hydrosilylation catalysts. These complexes are effective for efficiently catalyzing hydrosilylation reactions, as well as offering improved selectivity and yield over existing catalyst systems.
CONVERSION OF WASTE PLASTICS TO HIGH-VALUE METABOLITES
A non-human organism for upgrading intermediate oxidation products formed by catalytic degradation of alkanes or polystyrenes is provided. The non-human organism is genetically modified to convert the intermediate oxidation products to secondary metabolites, and in particular to include a positive feedback loop construction in the promotor system. A method includes steps of catalytically degrading alkanes or polystyrene in an oxidizing environment to form intermediate products with one or more catalysts and contacting the intermediate products with the non-human organism such that intermediate oxidation products are converted to secondary metabolites.
