| Abstract: | The technique for wood liquefaction has attracted considerable attention in the field of effective utilization of woody biomass.Wood is difficult to be melted or dissolved,therefore restricting its application.The lignocellulosics can be converted to liquid reactive materials by liquefaction in organic solvents such as polyols. Liquefied products could partly replace petroleum-based polyether polyols and polyester polyols as raw materials for synthetic polymer resins.This paper describes liquefaction method by polyols,liquefaction mechanism and application of liquefied products to polyurethane. |
