Homogeneous Catalyst Recovery and Recycle with Co2
Catalytic synthesis can be achieved by using either homogeneous or heterogeneous organometallic complexes, or homogeneous enzymatic biocatalysts. However, each of these methods offers advantages and disadvantages that must be balanced cautiously. Homogeneously catalyzed reactions are highly efficient in terms of selectivity (i.e. regioselectivity, enantiomeric excesses) and reaction rates, due ...
متن کاملNovel Homogeneous Nickel(II) Catalyst
The present invention relates to new Nickel catalysts of Formula I and II and to the process of preparation of the new catalysts. These new catalysts are used in preparing poly(3-substitutedthiophene) with high regioregularity. Highly regioregular poly(3-substituted-thiophene) can be used in the manufacture of optoelectronic devices. Patent application No.523/MUM/2014
متن کاملHomogeneous Catalyst for Alkane Dehydrogenation
The removal of hydrogen from alkanes to give alkenes is an important commercial objective, as alkenes are widely used as organic feedstocks in industrial processes involving chemical synthesis and polymerisation. This reaction is, however, significantly endothermic, needing up to 30 kcal per mole, and normally occurring at temperatures exceeding 400°C in the presence of heterogeneous supported ...
متن کاملHomogeneous Catalysis and Catalyst Recovery Using Supercritical Carbon Dioxide and Ionic Liquids
The combination of scCO2 with a non-volatile liquid such as ionic liquids, water, or poly(ethylene glycol) creates a biphasic mixture suitable for homogeneous catalysis with facile catalyst/product separation and catalyst recycling. Continuous-flow processes are also possible. Dissolution of the CO2 into the nonvolatile liquid during the reaction can have desirable or undesirable effects on the...
متن کاملHow to Find the Best Homogeneous Catalyst
We present in this communication an alternative concept for optimising homogeneous catalysts. With this method, one extracts and screens virtual catalyst libraries, indicating regions in the catalyst space where good catalysts are likely to be found. This automated screening is done in two stages: A ‘rough screening’ using 2D descriptors, followed by a ‘fine screening’ using 3D descriptors. The...
