|Title||:||Kinetic Studies of Glycolic Acid –PMS System In the Presence Of Fe (II)|
|Authors||:||S. Muthu Priya || S. Shailaja|
Abstract: The kinetics of the reaction between peroxomonosulphate with glycolic acid was studied in the presence of Fe(II) in the pH range 4.05 to 5.2 at 304K. The reaction followed second order with respect to peroxomonosulphate. The rate of the reaction increases with the [Fe(II)] and independent with respect glycolic acid. A plot of k2obs vs 1/[H+] is a straight line passing through origin. Based on the results a rate equation, kinetic scheme and a most probable mechanism has been predicted.
Keywords: Glycolic acid, Peroxomonosulphate, Kinetics, Alphahydroxy acid, Catalyst.

|Title||:||A Novel Route of Synthesize the Monomer 3, 6- Di- isocyanato N-substituted Carbazole and its Photo conducting Polymers with Ethylene diamine, Tri methylene diamine and Tetra methylene diamine|
|Authors||:||Dipak Kumar Mukhopadhyay|
Abstract: The monomer 3, 6- Di- isocyanato N-substituted Carbazole has been synthesized and three substituted poly ureas have been synthesized by the reaction of monomer 3, 6- Di isocyanato N-substituted Carbazole with ethylene diamine, tri methylene diamine and tetra methylene diamine. The substituted poly ureas have been characterized by IR, UV and NMR spectroscopy.
Keywords: 3, 6- Di- isocyanato N-substituted Carbazole, substituted poly ureas, Interfacial polymerization.
