Conversion of Residual lignin generated during bioethanol production to functional materials for environment conservation

为了将木质纤维素原料生产生物乙醇过程中产生的残余木质素转化为环保功能材料，进行碱水热处理，然后与丙烯酸发生共聚。然而，由于木质素与丙烯酸的相容性差，共聚反应未能成功。将木质素与ε-己内酯共聚，得到具有高溶胀性的功能性聚合物。研究了水热处理对残余木质素的增溶机理。

In order to convert the residual lignin generated during bioethanol production using lignocellulosic materials into functional materials for environmental conservation, hydrothermal treatment with alkali was conducted followed by co-polymerization was occurred with acrylic acid. However, the co-polymerization was not succeed because of poor compatibility between the lignin and acrylic acid. The lignin was co-polymerized withε-caprolactone to obtain the functional polymer with high swellability. The solubilization mechanism of residual lignin by hydrothermal treatment was investigated.
