Low temperature solution growth (LTSG) is one of the most efficient and simplest processes which can be employed for crystal growth from solutions. The ease in handling and the readiness in its miscibility with the solvents make it an attractive technique for crystal growth. Most of the chosen solutes are miscible with water and some are with alcohol and ethers. Benzophenone a photoinitiator used in the UV-curing applications in inks, adhesive and coatings, optical fibers and in printed circuit boards. Benzophenone or di-phenyl ketone (CAS No. 119-61-9) with chemical formula (C6H5)2CO is miscible with ethanol in optimal proportions. The solution is heated for supersaturation well below its boiling point. The supersaturated solution is then taken in a beaker and kept for crystallization. Normal nucleation followed by crystallization happens by evaporation technique at room temperature. A provision for rapid evaporation by a stream of uniform hot air flow across the growth chamber enhances the crystallization rate thereby reducing the time required for the growth of crystals. This acceleration of crystal growth is an important prerequisite for the mass crystallization and industrial crystal growth. The crystals are analysed for their surface, structural and spectroscopic characteristics.
