摘要

由於人類長期依賴著石油,因此造成石油短缺,我們在此開發一個新的製程,可以從農業廢棄物纖維素轉化成多醇類,再由多醇類進行醚化,可以得到能與現行商用燃料互溶的添加劑。
我們把實驗分成第一部份以及第二部分,第一部分著重於如何將纖維素利用氧化還原以及水解反應得到多醇類,實驗原理來自史密斯降解。並且將產物以HPLC分析,配合檢量線來計算出產物量。還有討論其反應變因,反應溫度為25度、45度、65度,反應時間為1hr、2hr、4hr以及改變其氧化劑探討對原實驗之影響。
第二部分實驗為赤蘚糖醇以及山梨糖醇之醚化實驗,將反應物與氫氧化鈉以及硫酸二甲酯做反應,並且討論其反應變因。反應變因為反應時間、反應溫度以及H2O/NaOH莫爾比(mol/mol),找出最佳反應時間。

Human long-term dependence on oil, thus creating a shortage of oil, we develop a new process from agricultural waste cellulose into alcohols, ethers of polyols, can be obtained with the existing commercial fuelmiscible additives.
The experiment is divided into the first part and second part of the first part focuses on how to cellulose use of redox and hydrolysis reaction of the polyols, the experimental principle from the Smith degradation. And product by HPLC analysis with a calibration curve to calculate the product of the amount. There is discussion of the reaction variables, the reaction temperature is 25 degrees, 45 degrees, 65 degrees, the reaction time was 1hr, 2hr, 4hr and change its oxidant to explore the impact of the original experiment.
The second part of the experiment, methylation experiments by using erythritol, and sorbitol, the reaction material with sodium hydroxide and dimethyl sulfate reaction, and discuss its response variables. Response variable because the reaction time, temperature and H2O/NaOH molar ratio (mol / mol), to identify the optimum reaction
time.
