摘要
在微波辐射下,以超稳Y沸石负载硅钨酸(HSW/USY)为催化剂,不使用溶剂,合成了肉桂酸β-苯乙酯。其优化反应条件是:负载量为20%的HSW/USY催化剂1.2 g,肉桂酸27 mmol,β-苯乙醇43 mmol,微波辐射功率600 W,辐射时间10 min,产率达91.5%。产物经过红外光谱表征。
β -Phenylethyl cinnamate was synthesized from cinnamic acid with β -phenylethyl alcohol using ultra stable Y zeolite supported silicotungstic acid (HSW/USY) as catalysts without solvent under microwave irradiation. Under the optimum reaction conditions, HSW/USY (loaded amount 20%) 1.2 g, cinnamic acid 27 mmol, β -phenethyl alcohol 43 mmol, microwave power 600 W, microwave irradiation time 10 min), the yield of ester was 91.5%. The product was characterized by IR.
