Evaluation Method of Solubility of Wheat Straw in LiCl/DMSO Solvent北大核心CSCD

In order to solve the quantitative problem of the solubility of lignocellulosic biomass in the solvent system, wheat straw was studied as raw material for a ball milling time on its dissolution behavior in the LiCl/DMSO system. The dissolution performance was evaluated by visual method, optical microscopy and turbidity method respectively. By comparison of visual colorimetry method and the optical microscopy method at the condition of wheat straw dissolved in 8% LiCl/DMSO, it was found that the turbidimetric method is accurate, simple and quantitative. The turbidimetric method can be used to evaluate the dissolution behavior of lignocellulosic biomass during pretreatment and refining. © 2018, Editorial Board of «Chemistry and Industry of Forest Products».
