摘要:
合成8种磺酸基功能化季铵盐离子液体,测定其腐蚀速率,并以离子液体为催化剂催化油酸与甲醇发生酯化反应制备生物柴油,研究工艺条件对生物柴油产率的影响.结果表明:离子液体［(CH3CH2)3N-(CH2)3SO3H］ ［C7H7O3S］对黄铜、碳钢、不锈钢的腐蚀速率分别为硫酸的1/345,1/38和1/608,酸与甲醇和离子液体的摩尔比为 1∶4∶0.05,反应温度为120 ℃,反应时间为0.5 h,则生物柴油产率可达97.83%;催化剂重复使用5次后活性无明显变化,表明其催化油酸制备生物柴油的稳定性高,离子液体可回收重复使用.
Abstract:
Eight kinds of SO3H-functional quaternary ammonium ionic liquids(ILs)were synthesized, corrosion rate of ILs were measured, and the yield of preparation of biodiesel from methanol and oleic acid through catalytic esterification catalyzed by ILs under different process conditions were discussed. The results show that the corrosion rate of ［(CH3CH2)3N(CH2)3SO3H］［C7H7O3S］ is only 1/345,1/38 and 1/608 of brass, carbon steel and stainless steel, compared with sulfuric acid. When n(Acid)∶n(MeOH)∶n(IL)=1∶4∶0.05, react temperature at 120 ℃, react time was 0.5 hours, the yield of biodiesel could be achieved 97.83%. Ionic liquids were recovered and reused five times, the yield is not obviously decreased, which indicate that the ionic liquids are stable, and could be recoveried and reused.
