Synthesis, Spectral Analysis and Evolution of Antimicrobial Activity of Schiff Base of Cyanoacetohydrazide

Jadeja J., Mamtora M., Gondaliya M. B., Manawar R., Shah M. K.

International Letters of Chemistry, Physics and Astronomy

2015

Vol. 52

100--110

In search of some antimicrobial agents, synthesis of some Schiff base of cyanoacetohydrazide derivatives has been reported. The structures of all the synthesized compounds were established on the bases of various spectroscopic methods. All Schiff base were screened for antimicrobial activity. cyanoacetohydrazide were found to possess better antimicrobial potential.

Synthesis and Thermal Stability of Melamine-Formaldehyde-Nitro Aniline Ion-Exchange Resin

112--118

A series of resins was synthesized and analyzed for selective ion-exchange nature for some metals. Substituted aniline was reacted with formaldehyde, melamine. For the synthesis of ion-exchange resins, sulfuric acid was used as a catalyst. These resins were characterized by elemental analysis and studied antimicrobial activities. Synthesized Resin shows ion exchange capability and moderate activity against microbial. Ion exchange resin also showed reusability and stability at an elevated temperature.

Reusable Nanocatalyst: Zirconia and Sulfated Zirconia

Gondaliya M. B., Maheta T., Mamtora M. J., Shah M. K.

295--302

1,5-benzodiazepines have been synthesized by Nano Zirconia and Nano Sulfated Zirconia in solvent free conditions. Synthesis was carried out by conventional as well as microwave method. Benzodiazepines were synthesized by reacting o-phenylenediamine and few ketones in the presence of catalytic amount of Nanoparticles. Particles used were sized in between 53-100 nm. Nanoparticles were characterized by FT-IR, DLS and powder XRD analysis.
