Steady-state macroscale voltammetry in a supercritical carbon dioxide medium

Steady-state macroscale voltammetry in a supercritical carbon dioxide medium.

The electrochemical oxidation and reduction of decamethylferrocene is demonstrated in supercritical carbon dioxide at a macro gold disc electrode at 100 bar and 313 K. Fast mass transport effects were exhibited and the corresponding steady-state voltammetry was observed at high scan rates. A highly lipophilic room temperature ionic liquid that readily dissolved in supercritical CO(2) with aceto...

Reactions in supercritical carbon dioxide

Use of conventional organic solvents often leads to the formation of hazardous waste, the disposal of which is a matter of environmental concern. Carbon dioxide is considered to be a green reaction medium and a good replacement for conventional organic solvents as it is benign and leads to elimination/reduction of hazardous wastes. Use of CO2 at near/above critical conditions has several additi...

Measurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide

Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...

Synthesis of polyvinyl pyridine/C60 conjugates in supercritical carbon dioxide*

In the present investigation efforts have been made to synthesis polyvinyl pyridine (PvPy) /C60 conjugates through 2, 2-azobisisobutyronitrile (AIBN) initiated insitu polymerization of PvPy in scCO2.The process of synthesis was monitored under different reaction conditions ranging 1200-1800psi, 60-90 oC over 6 hours. The progress of polymerization was monitored rheoviscometrically. The concentr...
