- W2393669833 abstract "Using phenol as liquefier,and catalyzed by phosphoric acid,factors influencing the liquefaction of Acacia mangium willd bark were investigated,such as temperature,amount of catalyst,time,and ratio of solvent to solid material.The optimal conditions were obtained by orthogonal experiment,and factors influencing the resinification of liquefied products were also studied.The results showed that:(1) the proportion of solid residue decreased significantly with the increase of temperature,amount of phosphoric acid,and liquificaion time;(2) orthogonal experiment indicated that the principal factor during was temperature, the optimal conditions were as follows:temperature:170℃,amount of catalyst:9%,time of liquification:2.5 hours,ratio of phenol to the bark:4.5:1,the residues rate:20.1%;(3) the resinification of liquefied products,indicated that the molar ratio of formaldehyde to liquefied products,reaction temperature and holding time had significant impacts on the viscosity of phenol-formaldehyde resin,the characters of liquefied products resin can meet the standards of GB/T 17657-1999 4.15 for wood industry." @default.
