摘要以木薯澱粉為原料,用醋酸酐為酯化劑,以乙酸為分散遞質,探索了以濃硫酸、對甲基苯磺酸、十二烷基苯磺酸為催化劑對澱粉醋酯化反應的影響。Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite, vitrinite and fusinite from jurassic coals in tarim basin at different temperatures. the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds. vitrinite is mostly composed of aromatic compounds, in addition to large amount of short aliphatic - side chain compounds. whereas fusinite are dominant by aromatic structure. the study indicates that cutinite is one of the best oil source - rocks, with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks, and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential. in addition, the components of aliphatic structures of cutinite, vitrinite and fusinite decrease, the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature, and along with the rise of temperatures, the intensity of aliphatic structure and heteroatomic compounds decrease obviously, however the aromatic structure changes a little
應用顯微紅外光譜技術,對塔里木盆地侏羅紀煤中有代表性的3種組分角質體鏡質體絲質體在不同熱模擬溫度下的結構組成變化特徵進行了研究,結果表明:角質體結構組成中含有較豐富的長鏈脂族結構,而芳香結構和含氧官能團的含量則相對較少與此相反,絲質體結構組成中芳香烴占絕對優勢,而脂族結構含量則很少鏡質體結構組成介於角質體和絲質體之間,含有較多的短鏈脂族結構和芳香結構。One lignin unit was found to be oxidized by about 3 electrons as an average when kappa number of the pulp became about half ( from 25. 4 to 13. 4 )
只有第一階段氧化反應是木質素與氧氣直接反應,而在第二、三階段主要是協同氧化作用,氧化反應過程中產生的活性氧基團扮演了一定角色。These results confirmed quantitatively that lignin oxidation is essential for the delignification during oxygen bleaching
