Summary on Grant Application Form |
|
In industrial organic synthesis, there are many existing oxidation processes using soluble oxidants, whose reactions and generation steps lead to the production of large quantities of waste products. However, the development for a clean catalytic selective oxidation process at low temperatures has been met with little success because of many technical problems such as difficulties in developing active catalysts at low temperatures; cost and safety of using other cleaner oxidents/catalysts; poor stability of substraints and products under reaction conditions (especially complex fine chemicals are not stable in H202) and limited choice of solvent (chemically inert to oxidation), etc. The aim of this research is to determine the scientific and technical feasibility of carrying out selectiveoxidation processes using air over noble metal catalysts in supercritical CO2. It is anticipated that the supercritical CO2 as a solvent is akin to an organic solvent but is non-combustible. It could provide a stimulus to performing complex fine chemical oxidation processes where no current catalytic method is applicable. Other benefits associated with the use of supercritical CO2 including rate enhancement due to its intrinsic excellent transport properties, organic solvent-free operation (environmental benign) and ease of separation are also apparent.
