无溶剂体系中酶法合成2-辛基十二烷醇酯(英文)
Lipase-catalyzed Synthesis of 2-Octanyl-dodecanol Stearicate by Direct Esterification in a Solvent-free Medium
【摘要】 考察了无溶剂反应体系下脂脂酶催化直接酯化合成 2 -辛基十二烷醇酯。在 mol醇 ∶mol酸 =1.6∶ 1,反应温度 60℃ ,脂肪酶添加量 4% ,反应时间 10 h的最佳条件下 ,酯化率可达94.8%。
【Abstract】 The synthesis of 2-octanyl-dodecanol stearicate from stearic acid and Guerbet alcohol was investigated in a solvent-free medium by lipase catalysis. The optimum reaction conditions were established as follows: mol_alcohol∶mol_acid=1.6∶1, temperature 60℃, amount of lipase 4%, reaction time 10h. The highest conversion reached 94.8%.
