| 以月桂酸甲酯和蔗糖为原料，通过水力空化强化酯交换合成蔗糖月桂酸单酯。研究了水力空化压力、水力空化时间、水力空化温度、糖酯摩尔比等对蔗糖月桂酸单酯产率的影响。以单因素实验为基础，利用响应面优化了水力空化强化酯交换合成蔗糖月桂酸单酯工艺条件，并对蔗糖月桂酸单酯产物表面活性性能进行了测定。结果表明：水力空化强化酯交换合成蔗糖月桂酸单酯最佳工艺条件为水力空化时间85 min、水力空化压力0.35 MPa、催化剂无水碳酸钾用量11.5%（以月桂酸甲酯用量为基准）、溶剂二甲基亚砜用量8.5 mL（以0.01 mol蔗糖为基准）、水力空化温度65?℃、糖酯摩尔比3.5∶?1，在最佳条件下产率为85.07%，蔗糖月桂酸单酯产物表面活性性能优越。 |
| 英文摘要: |
| Hydraulic and vacuum were used to enhance the synthesis of sucrose laurate using sucrose and methyl laurate as raw materials. The effects of hydrodynamic cavitation pressure, hydrodynamic cavitation time, molar ratio of sucrose to methyl laurate, and hydrodynamic cavitation temperature on the yield of sucrose laurate were researched. Based on single factor experiment, the optimal synthesis conditions were obtained using response surface methodology, also the surface activity of sucrose laurate was determined. The results showed that the optimal synthesis conditions were obtained as follows：hydrodynamic cavitation pressure 0.35 MPa, hydrodynamic cavitation time 85 min, hydrodynamic cavitation temperature 65?℃, molar ratio of sucrose to methyl laurate 3.5∶?1, dimethyl sulfoxide solvent dosage 8.5 mL(on the basis of 0.01 mol sucrose)and catalyst anhydrous potassium carbonate dosage 11.5%(on the basis of the mass of methyl laurate). Under these conditions, the yield of sucrose laurate was 85.07%, and the surface activity of the product was superior. |
