Growth and Characterization of Benzophenone and Mixed Crystal of Benzophenone and 2,4-Dinitrophenyl hydrazone of Benzophenone

Abstract

Good quality benzophenone crystals were grown by solution technique using CHCl₃ as solvent by adopting slow evaporation method at room temperature. The grown crystals were subjected to various characterization studies to analyze of its purity and applications. The condensation product 2,4-dinitrophenyl hydrazone of benzophenone (DNPBP) was prepared by adopting standard procedure. Then mixed crystal of benzophenone and DNPBP was grown by solution growth. Both the condensation product and mixed crystals were characterized by UV, FTIR, ¹H NMR thermal studies reveals the purity of the product. SHG efficiency of the grown crystals was determined.
