Effects of Pretreatment On Chemical Modification of Poplar Wood Flour and Thermo-flowability of Modified Wood Flour
In this paper,effects of various pretreatment on reactivity of wood flour,thermo-flowability and solubility of chemically modificated wood flour were studied.Results shownthat three- dimensional network structure of lignin molecule in wood flour was changed afterpretreatment of heating and saturated chlorine solution,resulting in thermo-flowability ofhydroxyethyethylated and in decrease of thermal flow temperature of benzylated wood flourtested.Moreover,the solvent-s lubility of chemically modificated wood flour was improvedby various pretreatment.
