Br?nsted酸性离子液体催化麻疯树油制备生物柴油
|
摘要
合成了Br?nsted酸性离子液体[HSO_3-pmin]~+[HSO_4]~-,采用FT-IR表征了结构,并用该离子液体作为催化剂催化麻疯树油制备生物柴油。研究了反应温度、醇油比、反应时间和催化剂用量对生物柴油转化率和酸值两种因素的影响,分析酸值和转化率之间的关系。实验结果表明:在反应温度70℃,醇油比25∶1,反应时间3 h,催化剂用量油重3%条件下,转化率为90.13%,所得生物柴油酸值(KOH)仅为0.049 mg/g,GC-MS测定生物柴油中脂肪酸甲酯的相对含量高达100%。离子液体稳定性较好,循环使用6次仍然保持较高催化活性。
A Br?nsted acidic ionic liquid[HSO_3-pmin]+[HSO_4]-was synthesized and characterized by FT-IR.The ionic liquid was used as catalyst to catalyze the preparation of biodiesel from jatropha oil.The effects of reaction temperature,molar ratio of methanol to oil,reaction time and catalyst dosage on biodiesel conversion and acid value were studied,and the relationship between acid value and conversion rate was analyzed.The experimental results showed that the optimum reaction conditions were reaction temperature 70℃,the molar ratio of methanol to oil 25∶1,the reaction time 3 h,catalyst dosage 3% of oil,the biodiesel having a conversion rate of 90.13% and an acid value of only0.049 mg/g was obtained.The relative content of fatty acid methyl ester in biodiesel prepared under these conditions was determined by GC-MS to be as high as 100%.The ionic liquid has no obvious change in catalytic activity after being used 6 times.
