| Abstract: | Bagasse xylan phosphate was synthesized by using bagasse xylan as raw materials,NaH2PO4 and Na2HPO4 as esterifying agent,urea as catalyst under the wet process,The influence of reaction conditions on the degree of substitution was investigated,such as reaction temperature,reaction time,xylan and esterifying agent ratio,xylan and catalyst ratio,reaction pH and so on.Synthesis conditions was systematically investigated adopted to orthogonal experimental design,and statistical analysis was used to research the... |
