Solubility Measurement and Correlation of Carbazole in Four Solvents
摘要
Abstract
The solubilities of carbazole were determined in four organic solvents,N,N-dimethyl formamide,xylene,tetrachloroethylene,and diethylene glycol dimethyl ether using a self-made liquid-solid equilibrium equipment.The solubility data were correlated by the modified Apelblat model,van't Hoff equation and λh equation,separately.The results show that the solubility of carbazole in four investigated solvents increased with increasing temperature,a big discrepancy of solubility was found in different solvents because of the different interaction between solute and solvent.The solubility data decreased in the order of DMF,DGDE,xylene,TCE.The calculated solubility data of the modified Apelblat model,van't Hoff equation and λh equation showed a good agreement with the experimental data.Moreover,the results of λh equation are much better than those of modified Apelblat model.The thermodynamic parameters gained from van′t Hoff equation indicate that the dissolution process was endothermic and non-spontaneous.关键词
