Determination and correlation solubility of 4-nitroimidazole in twelve pure solvents from 278.15 K to 323.15 K

摘要

In this paper,the solubility of 4-nitroimidazole in twelve pure solvents(toluene,benzene,1,4-dioxane,acetonitrile,ethyl acetate,acetone,GBL,ethanol,methanol,n-butanol,DMF and NMP)were determined by using the laser monitoring system from 278.15 K to 323.15 K under 101.1 k Pa,which are 0.00018–0.00070,0.00021–0.00073,0.00034–0.00092,0.00038–0.00142,0.00047–0.00120,0.00126–0.00303,0.00225–0.00517,0.00310–0.00724,0.00467–0.00982,0.00453–0.01940,0.01947–0.04652,and 0.04670–0.07452,respectively.At constant temperature,the mole fraction solubility of 4-nitroimidazole were increased as the following order:toluene
