| 摘 要： | 考察不同有机溶剂添加条件下,ChCl/PCA对中药渣合欢皮预处理效果的影响。以物质的量之比1∶1合成ChCl/PCA的低共熔溶剂中加入质量分数为10%的甲酸,在固液比1∶10、160℃条件下反应3 h时,原料损失率为59.57%,木质素、半纤维素、纤维素的脱出率分别为59.11%、100%和37.13%,高于单纯甲酸及ChCl/PCA的木质素脱除效果。

| Abstract: | Herein,different organic solvents were added into ChCl/PCA to reduce the viscosity,and the effect of these organic solvents on ChCl/PCA pretreatment of herb residues of cortex albiziae was investigated.When 10%(w/w)of formic acid(Fa)was added to the ChCl/PCA(molar ratio of 1∶1)under the condition of solid-liquid ratio of 1∶10 at 160℃for 3 h,the loss of feedstock was 59.57%and lignin removal reached 59.11%with 100%hemicellulose removal and 37.13%cellulose removal.Fa/ChCl/PCA gave a higher lignin removal compared with the pure formic acid and single ChCl/PCA. |
