ABSTRACT

The present study reports the synthesis, characterization and solubility of (E)-2-(4-chlorobenzylidene) -3,4-dihydronaphthalen-1(2H)-one. The compound was synthesized by standard process. The purity was monitored by TLC and confirmation of structure was done by using mass, IR and 1H NMR spectral techniques. Further, solubility study of this synthesized compound was conducted in methanol, ethanol, 1-propanol, 1-butanol, tetrahydrofuran (THF), ethyl acetate (EA), acetone (AC) and chloroform (CF) at temperatures ranging from (293.15 to 323.15) K under atmospheric pressure. Further, the solubility data were correlated against temperature and were found to increase with temperature. The modified Apelblat and Buchowski Ksiazczak kh equations were used to correlate the experimental solubility data. Further, some thermodynamic parameters such as dissolution enthalpy (DH), Gibbs free energy (DG) and entropy (DS) of mixing have also been calculated. The positive enthalpy and Gibbs free energy values suggest the dissolution process to be endothermic and spontaneous.
