Various organic oxidants including tert-butyl peroxybenzoate, tert-butyl hydroperioxide (TBHP), hydrogen peroxide-urea adduct, dicumyl peroxyide and peracetic acid solution were studied for the oxidation of methane to methanol via methyl acetate catalyzed by iodine in non-aqueous acetic acid medium. Among these organic oxidants investigated, tert-butyl hydroperioxide (TBHP) exhibited the highest methane conversion. The effects of various kinetic factors on the catalytic behavior of the TBHP-I2 system were investigated, and a quantitative yield of methyl acetate (18.9%) based on methane has been obtained under the optimized conditions. A possible mechanism involving electrophilic displacement has been suggested for this reaction.

Abstract The method of Barakat and co-workers for determination of vitamin C in colored products has been modified for potentiometric use. The procedure is simple and rapid: An aliquot of sample containing 1—3 nig of ascorbic acid is titrated in a 3% acetic acid medium in the presence of KI with previously standardized 0.01% N-bromosuccinimide. The potentiometric titration uses two Pt electrodes with a polarizing current. Results were compared with the USP XVI method and the AOAC 2,6-dichlorophenol indophenol method. Recoveries, obtained from seven commercial products, four of which were vitamin C-enriched, ranged from 96 to 101%. The method also works well on drug mixtures containing ascorbic acid. It is recommended that the method be studied collaboratively.
