Oxidation System

A systematic study of the oxidation of 3-hydroxy-2-substituted isoindolin-1-ones (hydroxylactams) and their conversion to the corresponding phthalimides was undertaken using three oxidants. Of special interest was the introduction of nickel peroxide (NiO2) as an oxidation system for hydroxylactams and comparison of its performance with the commonly used pyridinium chlorochromate (PCC) and iodoxybenzoic acid (IBX) reagents. Using a range of hydroxylactams, optimal conversions of these substrates to the corresponding imides was achieved with 50 equivalents of freshly prepared NiO2 in refluxing toluene over 5–32 h reaction times. By comparison, oxidations of the same substrates using PCC/silica gel (three equivalents) and IBX (three equivalents) required oxidation times of 1–3 h for full conversion but required lengthier purification. While nominal amounts (~25 mg) of substrate hydroxylactams were used to ascertain conversion, scale-up procedures using all three methods gave good to excellent isolated yields of imides.

Oxidation System

In this study, for the first time nanostructured TiO2 and Fe2O3 was loaded on active carbon cloth (ACC) as electrodes to be used in an electrochemical oxidation system. This novel TiO2-ACC and Fe2O3 / TiO2-ACC composite electrodes(or modified electrodes) were characterized by scanning electronmicroscopy (SEM)and cyclic voltammetry(CV).During the degradation of dye wastewater, electrochemical oxidation system with TiO2-ACC and Fe2O3 / TiO2-ACC electrodes showed much higher activity than with ACC electrodes. The system with Fe2O3 / TiO2-ACC electrodes acquired the best COD removal: the COD of wastewater decreased from 33000 mg/L to 8700mg/L. The removal rate of COD reached 74%, which was 19% higher than ACC system.
