Quantitative Research on Solubility Property of Straw Wheat Alkali Lignin
摘要
Abstract
For quantitative characterizing the solubility properties of wheat straw alkali lignin, the solubility parameters were measured by inverse gas chromatography(IGC) and Hansen solubility parameter(HSP) method. By IGC method, the solubility parameter(δ2) and the related thermodynamic properties of wheat straw alkali lignin were determined in 403.15-443.15 K;wheat straw alkali lignin was used as the stationary phase, and 7 classes of 20 kinds of organic solvents,namely aliphatic, cycloaliphatic,aromatic hydrocarbons,alcohols, ketones, halohydrocarbons and tetrahydrofuran totally 7 classes of 20 kinds of organic solvents were used as the probe molecules;the δ2was derived as 20.09(J/cm3)0.5at 298.15 K by linear extrapolation and the δ2increased with the increase of temperature in 403.15- 443.15 K. By HSP method, the solubility parameter(δT) was measured as 20.68 (J/cm3)0.5at 298.15 K. The δ2and δTvalues were consistent by IGC and HSP method. And tetrahydrofuran, alcohols and ketones had a good trend of solving straw alkali lignin.关键词
