Determination of chloramine T in dairy products.
A method has been developed for the quantitative determination of traces of chloramine T (Activin, Halamid) in dairy products. Proteins are removed and the hydrolysis product toluene-4-sulphonamide is extracted with ether. After evaporation of the solvent, the residue is oxidized with an alkaline potassium permanganate solution. The oxidized product is isolated by ether extraction and the resid...
متن کاملOxidation of Some Aliphatic Aldehydes by Chloramine-t
Kinetic studies on the oxidation of acetaldehyde, propionaldehyde, nand tso-butyraldehyde have been made using diloramine-T as an oxidising agent in an alkaline medium. The reactions followed almost identical kinetics being first order with respect to both aldehyde and chloramine-T. The order with respect to alkali has been found to be almost equal to unity (0.8 to 0.90) . Effect of an increase...
متن کاملStereoselective aziridination of cyclic allylic alcohols using chloramine-T.
The stereoselective aziridination of a range of cyclic allylic alcohols using two different chloramine salts (4-MeC(6)H(4)SO(2)NClNa, TsNClNa and t-BuSO(2)NClNa, BusNClNa) has been explored. The stereoselectivity of these reactions was highly dependent on the structure of the allylic alcohol and the chloramine salt. Generally, mixtures of cis- and trans-hydroxy aziridines were obtained, in whic...
متن کاملOxidation of tricyclic antidepressant drugs with chloramine-T in acidic solutions: kinetic, mechanistic and thermodynamic studies
The kinetics of the oxidation of two tricyclic antidepressants (TCA) namely, imipramine (IMP) and clomipramine (CLM) with sodium N-chloro-p-toluenesulfonamide or chloramine-T (CAT) in HClO4 medium was studied at 300 K. The two reactions followed identical kinetics with a first-order dependence of rate on [CAT]o and fractional order dependence on [TCA]o. The reaction is catalyzed by H(+) ions wi...
متن کاملIodination of Escherichia coli with chloramine T: selective labeling of the outer membrane lipoprotein.
Iodination of Escherichia coli cells with chloramine T preferentially labels the free and murein-bound forms of the outer membrane lipoprotein. Iodination for 15 s at 15 degrees C labels the two forms of the lipoprotein almost exclusively, whereas iodination for 60 s at 25 degrees C also labels the other major outer membrane proteins. Chloramine T iodination is a rapid, simple technique for lab...
