Synthesis, Crystallographic, Monoclinic, Inflexible, Antifungal Assessment of Schiff based resin

Abstract

The present study investigates the preparation of a newly prepared Schiff base BHNMXD and Schiff based resin PMBHNMXD via polymerization. The condensation or polymerization procedure was used with formaldehyde (HCHO) at temperature 70 to 80 ˚C for 2-3 h. The prepared Schiff base BHNMXD and its respective resinPMBHNMXD were recrystallized from methanol to attain pure resin. After successful synthesis of Schiff base and resin was characterized by different instrumental techniques such as; CHN, elemental microanalysis, thermogravimetric analysis (TGA) studies of Schiff based resin, energy- dispersive x-ray spectroscopy EDS mass spectrometry, E.I-MS (electron impact ionization), 1HNMR spectroscopy and MALDI-TOF mass spectrometry clearly investigated the molecular weight and structural information of synthesized compounds. The FT-IR spectra of resin PMBHNMXD showed stronger absorption band at 1632 cm-1 of azomethine >C=NH confirming the compound formation. The SEM analysis showed the morphology of Schiff base and resin showing, longitudinal spherical rough, inflexible and rigid structure. The structures and components were carefully investigated by X-ray diffraction .The crystallographic evaluation of Schiff base and its resin, aproved the monoclinic sharp crystalline structure. These active materials have shown high efficiency against the antifungal growth of Aspergillus Flavus (G-ve), Candida albicans (G-ve) and Aspergillus Niger (G-ve),by agar well diffusion method.
