吉林省5种特色野生阔叶木材的化学组成分析
Chemical Composition Analysis of Five kinds of Wild Hardwood Species in Jilin Province
摘要
Abstract
The main chemical composition and key characteristics of lignocelluloses for 5 kinds of wild hardwood species in Jilin Province were characterized using techniques including the National Renewable Energy Laboratory(NREL)method,thioacidolysis,high-performance liquid chromatography(HPLC),and ion chromatography(IC),etc.Based on the results,the potential applications of these plant fibers in papermak-ing and other fields were disscussed and compared.The results showed that the cellulose content of the 5 kinds of wood types was similar,while the hemicellulose and lignin contents ranged from 16.68%to 24.88%and 17.82%to 26.15%,respectively.The average degree of polymer-ization(DP)of the isolated cellulose was 1 021～1 708,and the weight-average molecular weight(Mw)of hemicellulose was 45.83～73.78 kDa.Hemicellulose primarily consisted of various types of xylans(with glucans being secondary).Acid-insoluble lignin was dominating in the lignin of 5 kinds of hardwood with the S/G ratio ranged from 0.21 to 3.92.Comprehensive analysis indicates that Crataegus pinnatifida(mountain hawthorn)is the most suitable raw material among the 5 kinds of hardwoods in the pulping and papermaking field,while Sorbus pohuashanensis(Sorbus species)is the most suitable one applied in the lignocellulose-based biorefinery field.关键词
