PMAA microgel surface-supported phase transfer catalyst as reusable microreactors for ultra-deep desulfurization

Homogeneous oxidative desulfurization catalyzed by a recoverable reaction-controlled phase transfer catalyst based on trilacunary Keggin polyoxometalate

A phosphotungstic reaction-controlled phase transfer catalyst was prepared and applied for the homogeneous oxidative desulfurization. Excellent desulfurization efficiency was achieved at 60 °C and the catalyst can be easily separated and recycled with ideal results.
