微波輔助Canola油轉酯化反應之評估

Assessment of Microwave-assisted Transesterification Reaction of Canola Oil

摘要


以canola油進行轉酯化反應的試驗中,於油醇莫耳數比為1:9的條件,並在反應時間為1h且溫度設定為60℃以及反應後靜置0h之條件下,所產生的脂肪酸甲基酯總含量較高。利用微波輔助來進行轉酯化反應,當設定功率為550 W處理時間10 min的條件下,測得之脂肪酸甲基酯的總含量最高為0.786 g mL^(-1) biodiesel,此方法在生質柴油或脂肪酸甲基酯的總產量與反應所需的時間上,皆優於傳統轉酯化之方法。

並列摘要


Canola oil has been used as material source for transesterification reaction. Under the condition of oil/methanol molar ratio of 1:9 at 60℃ for 1 h without further incubation time, more fatty acid methyl esters (FAMEs) would be generated from canola oil. The highest amount of FAMEs (0.786 g mL^(-1) biodiesel) analyzed by GC was obtained under 550 W for 10 min by microwave-assisted transesterification. In considering the amount of biodiesel or FAMEs and reaction time, microwave-assisted transesterification of canola oil exceeds traditional transesterification method.
