The wet biomass microalgae of Nannochloropsis sp. was converted to biodiesel using direct transesterification (DT) by microwave technique and ionic liquid (IL) as the green solvent. Three different ionic liquids; 1-butyl-3-metyhlimidazolium chloride ([BMIM][Cl], 1-ethyl-3-methylimmidazolium methyl sulphate [EMIM][MeSO4] and 1-butyl-3-methylimidazolium trifluoromethane sulfonate [BMIM][CF3SO3]) and organic solvents (hexane and methanol) were used as co-solvents under microwave irradiation and their performances in terms of percentage disruption, cell walls ruptured and biodiesel yields were compared at different reaction times (5, 10 and 15 min). [EMIM][MeSO4] showed highest percentage cell disruption (99.73%) and biodiesel yield (36.79% per dried biomass) after 15 min of simultaneous reaction. The results demonstrated that simultaneous extraction-transesterification using ILs and microwave irradiation is a potential alternative method for biodiesel production.
采用微波技术和离子液体（IL）作为绿色溶剂，通过直接酯交换（DT）将小球藻属（Nannochloropsis sp.）的湿生物质微藻转化为生物柴油。使用了三种不同的离子液体：1-丁基-3-甲基咪唑氯化物([BMIM][Cl])、1-乙基-3-甲基咪唑硫酸甲酯盐([EMIM][MeSO4])和 1-丁基-3-甲基咪唑三氟甲烷磺酸盐([BMIM][CF3SO3])，以及有机溶剂（己烷和甲醇）作为共溶剂，在微波辐射下，比较了它们在不同反应时间（5、10 和 15 分钟）下的百分比破坏、细胞壁破裂和生物柴油产率。[EMIM][MeSO4]在同时反应 15 分钟后，显示出最高的细胞破坏百分比（99.73%）和生物柴油产率（每干生物质 36.79%）。结果表明，使用离子液体和微波辐射进行同时提取-酯交换是生物柴油生产的一种有潜力的替代方法。
