木聚糖作染料分散剂的研究
Study on Xylan as a Dye Dispersant
摘要
Abstract
In the processes of pulp and paper making as well as biomass processing,a large amount of hemicellulose has not been utilized for high-value applications.In this study,xylan-type hemicellulose,which was isolated from eucalyptus wood through an alkali pre-extraction system,was employed to prepare high-performance dye dispersants.The dye dispersion treated by the xylan-based dye dispersant can achieve a diffusion performance of level 5(in accordance with the HG/T3399-2001 standard),maintain a particle size stability of 229.4±3.72 nm after 130℃high temperature treatment,and has an average reduction-hydrolysis rate of 53.55%.These indicators meet or exceed those of synthetic commercial dye dispersants sodium methylenebis(NNO).This research is expected to offer novel ideas and approaches for the valorization of waste xylan,reduce the consumption of synthetic dye chemicals,ease the waste-discharge pressure,and propel the sustainable and eco-friendly development of dye dispersants.关键词
