In the present paper, a simple, and novel method for the abatement of paracetamol (PA) in aqueous system into environmental friendly compound benzoquinone at 308 K has been described, and was accelerated by simple, and inexpensive catalyst Cu(II)/Ni(II). A comparative assessment between Cu(II) and Ni(II)catalyzed, abatement of PA by CAT was performed. It has been determined that there are very little change in rate of reaction for both Cu(II)/Ni(II) catalyzed degradation of PA. All the kinetics parameters, i.e. the effect of change in concentrations of chloramine-T (CAT), sodium hydroxide, paracetamol, catalyst, added p-toluenesulfonamide, electrolyte etc. have been studied, and measured carefully. Reaction had been studied in the range of temperature 303-323 K. On the basis of kinetic data obtained a satisfactory mechanism has been proposed. And it was deduced that, presently used process was a tenable technique for the degradation of PA. Main abatement product was confirmed by GC-MS anal. technique. In the part of experimental materials, we found many familiar compounds, such as 4-Methylbenzenesulfonamide(cas: 70-55-3Quality Control of 4-Methylbenzenesulfonamide)
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic amines have the nitrogen atom connected to an aromatic ring.Important amines include amino acids, biogenic amines, trimethylamine, and aniline. Inorganic derivatives of ammonia are also called amines, such as monochloramine (NClH2).Quality Control of 4-Methylbenzenesulfonamide
