Solution Growth and Spectral Characterisation of 2-Bromo-4-Chloroacetophenone Crystals

The crystals of 2-bromo-4-chloroacetophenone (BCAP) were grown from carbon tetrachloride as solvent using slow evaporation technique at room temperature. In this chapter, by adopting cost effective slow evaporation solution growth technique was used to obtain transparent, good quality BCAP crystals. Solubility studies were made using this solvent at various temperatures. The crystals were carefully harvested and subjected to various characterization studies viz., UV, FTIR, 1H NMR, TGA- DTA and the Unit cell dimensions were determined. The various functional groups present in the grown crystal have been identified using FTIR spectra. The grown crystals were subjected to 1H NMR studies and thermal studies in order to confirm the structure and purity of the grown crystals, respectively. The transparency of the crystal was tested using UV-Visible spectral analysis. Solubility and metastable zone width studies of BCAP in CCl4 have been carried at various temperatures. SHG efficiency of the grown crystals was analyzed by kurtz powder technique.
