沙柳木材苯酚液化工艺及其结构表征
Phenol Liquefaction of Salix psammophila and Structure Characterization
摘要
Abstract
In order to develop optimal preparation technological procedure for the liquefaction of Salix wood,taking phenol as a liquefier,diluted sulfuric acid as a catalyst,effects of relative factors on the rate of liquefaction were investigated,such as reaction temperature,amount of catalyst,ratio of liquefier,and reaction time.Liquefier ratio exhibited the strongest influence on the liquefaction process,followed by reaction temperature,amount of catalyst,and reaction time.The optimal conditions were as follows:liquid ratio 7 ∶ 1,temperature 160C,10％ of catalyst,liquefaction time 120 min.FTIR analysis demonstrated that the molecular structure of Salix wood powder underwent significant changes,indicating the success of the liquefaction.关键词
