Here we present a rheol. study of enzymic hydrolysis lignin (EH lignin) in 1-butyl-3-methylimidazolium chloride ([C4min]Cl) aqueous solutions The effects of ionic liquid mass fraction, shear rate and temperature on the viscosity and macromol. chain configuration of EH lignin / [C4min] Cl aqueous solution were studied. The results showed that the viscosity of the aqueous solutions increased with the increase of lignin content. The mass percentages of overlapping and winding, responding to divisions of lignin macromols. existence state, were varied with changing in the temperature and mass percentages of ionic liquid Increasing the mass of ionic liquid will significantly change the viscosity of lignin solution Most of the lignin solutions had shear thinning behavior, suggesting that macromol. chains of lignin moved with orientation to the fluid, and disentangled under the shear force. The viscosity of lignin solution decreased with the increase of temperature, and the viscosity activation energy increased with the increase of lignin or ionic liquid mass fraction.
