摘要: 以糠酸和乙醇为原料、HCl为催化剂,采用微波辐射合成食用香料糠酸乙酯。在微波辐射功率、辐射时间、HCl溶液用量等单因素试验基础上,根据Box-Behnken试验设计原理,应用响应面分析法研究各因素的显著性和交互作用的强弱,对酯化反应工艺进行优化。结果表明微波辐射合成糠酸乙酯最佳工艺条件为:微波功率360W、辐射时间12min、HCl溶液用量1mL,酯化反应产率为83.8%,与理论预测值83.7679%的绝对误差为0.0321%。

Abstract: Ethyl furoate was synthesized by using HCl to catalyze the reaction between furoic acid and ethanol under microwave irradiation conditions. Using one-factor-at-a-time designs, microwave power, irradiation time and catalyst dose were identified as main variables that influence ethyl furoate yield. These variables were optimized by Box-Behnken experimental design in combination with response surface analysis. The optimal synthesis conditions for ethyl furoate were determined as addition of 1 mL of HCl solution and microwave irradiation at 360 W for 12 min. Under these conditions, the actual reaction yield of ethyl furoate was 83.8%, which was close to the predicted value of 83.7679% with an absolute error of 0.0321%.

Key words: ethyl furoate, microwave irradiation, response surface methodology (RSM), synthesis
