実験手順: A 2 liter one neck round bottom flask equipped with a Dean Stark trap, condenser and nitrogen, inlet outlet was charged with 150.0 g (1.66 moles) lactic acid, 293.0 g (2.25 moles) octyl alcohol, 6 ml sulfuric acid and 500 ml toluene. Mixture was heated to 130° for 2.5 hours and water was collected as the reaction proceeded. The acid was neutralized by washing three times with 50 ml saturated sodium bicarbonate solution. Approximately 50 ml ether was needed to break the emulsion. The organic layer was collected and dried over magnesium sulfate. Octyl lactate was distilled under high vacuum to yield 119.85 g (35.6% yield) of clear colorless liquid. According to GC the product is 96.2% pure. Mixture was heated to 130° for 2.5 hours water was collected as the reaction by washing three times with 50 ml saturated sodium bicarbonate solution The organic layer was collected dried over magnesium sulfate Octyl lactate was distilled under high vacuum

実験手順: A 500 mL one neck round bottom flask equipped with a distillation apparatus and nitrogen inlet/outlet was charged with 100.0 g (0.847 moles) of ethyl lactate, 220.49 g (1.69 moles) of octyl alcohol and 0.423 g of sulfuric acid (based on 0.5 g sulfuric acid/one mole ethyl lactate). The reaction was refluxed for 8 hours and ethanol was collected as formed. The acid was neutralized by washing three times with 100 mL saturated sodium bicarbonate solution. Approximately 50 mL ether was needed to break the emulsion. The organic layer was collected and dried over magnesium sulfate. Excess octyl alcohol was removed by high vacuum distillation, and three fractional distillations led to 75.0 g (44% yield) of clear colorless oil. According to GC, the product is 95% pure. The reaction was refluxed for 8 hours ethanol was collected as formed by washing three times with 100 mL saturated sodium bicarbonate solution The organic layer was collected dried over magnesium sulfate Excess octyl alcohol was removed by high vacuum distillation, and three fractional distillations
