Study of the Liquefaction Process of Larch Sawdust

By means of uniform design experimentation and regression analysis,the interaction between various factors involved in the liquefaction process of larch sawdust is obtained.Through gel permeation chromatography,inspection is conducted of samples of liquefied larch sawdust obtained under 8 different synthesis conditions,with number-average molecular weight and weight-average molecular weight obtained respectively.The result shows that no matter what liquefaction conditions,the molecular weight of liquefied samples is dominated by large molecules,to be exact,high molecule weight segments.
