Abstract: This paper reports cyclopentane, cyclohexane and cyclooctane oxidation in the presence of N-hydroxyphthalimide or 4-dodecyloxycarbonyl-N-hydroxyphthalimide in combination with Co(II) and Fe(II) salts using O2/CO2 mixture (0.5 MPa O2, 9.5 MPa CO2). The studies demonstrated that the application of scCO2 in cyclohexane and cyclooctane oxidation processes results in higher conversion and yield of respective ketone and alcohol in comparison to processes performed using air under pressure (0.7 MPa).

Keywords: Oxidation ; N-Hydroxyphthalimide ; Carbon dioxide ; Cyclopentane ; Cyclohexane ; Cyclooctane
