摘要

摘要采用不同条件下的水处理方法,制备了可溶性半纤维素衍生物桉木。采用分光光度、光谱和色谱相结合的方法,对得到最佳效果的处理液组成进行了深入表征;并在另外的实验中评估了处理后的固体对有机溶剂脱木质素进一步分馏的敏感性。测定了得到的木质素的化学和物理化学性质,并定量评价了脱木质素固体作为一锅法生产乙酰丙酸乙酯的底物的适用性。

Fractionation of Eucalyptus regnans wood: properties of the soluble products and reactivity of the treated solids
Abstract Eucalyptus regnans wood samples were treated with water under diverse conditions, in order to obtain soluble hemicellulose-derived products. The composition of the liquid phase from the treatment leading to the best results was characterized in depth using a combination of spectrophotometric, spectrometric and chromatographic methods; and the susceptibility of the treated solids to further fractionation by organosolv delignification was assessed in additional experiments. The chemical and physicochemical properties of the resulting lignin were determined, and the suitability of the delignified solids as substrates for the one-pot manufacture of ethyl levulinate was evaluated on a quantitative basis.

期刊介绍: The Journal of Wood Chemistry and Technology (JWCT) is focused on the rapid publication of research advances in the chemistry of bio-based materials and products, including all aspects of wood-based polymers, chemicals, materials, and technology. JWCT provides an international forum for researchers and manufacturers working in wood-based biopolymers and chemicals, synthesis and characterization, as well as the chemistry of biomass conversion and utilization. JWCT primarily publishes original research papers and communications, and occasionally invited review articles and special issues. Special issues must summarize and analyze state-of-the-art developments within the field of biomass chemistry, or be in tribute to the career of a distinguished researcher. If you wish to suggest a special issue for the Journal, please email the Editor-in-Chief a detailed proposal that includes the topic, a list of potential contributors, and a time-line.
