| 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: molalcohol : molacid＝ 1. 6 : 1, temperature 60°C, amount of lipase 4%, reaction time 10h. The highest conversion reached 94.8%. |
