Measurement and application on the solubility of tigogenin in methanol and ethanol
摘要
Abstract
The solubility of tigogenin in methanol (293-338K)and ethanol (293-353K)were determined by equilibrium method at atmospheric pressure, and the solubility date was correlated.The results showed that the solubility of tigogenin in methanol and ethanol increased monotonically with increasing temperature.The solubility of tigogen in methanol was greater than in ethanol at 293-323K,and in methanol was less than in ethanol above 323K.The adjusted determination coefficient of fitting equation was respectively 0.9961 and 0.9976,the average relative errors of solubility in methanol was 2.12% at 318-338K,in ethanol was 2.56% at 328-353K, which indicates that fitting equation can meet the need of engineering design.Applications of two solvents in production of tigogenin were studied,which show that ethanol as extraction solvent was better than methanol.关键词
