KF-Al_2O_3催化合成对甲氧基肉桂酸-2-乙基己酯的研究

Study on the catalytic synthesis of 2-ethylhexyl-p-methoxycinnamate by KF-Al_2O_3

研究了用 KF-Al2 O3 为催化剂 ,由对甲氧基苯甲醛和乙酸 -2 -乙基己酯发生 Claisen-Schmidt缩合反应 ,得到高收率的缩合产物 ,且为反式结构 ,并考察了诸因素对产率的影响 ,找出了最佳反应条件。

Condensation of 4-methoxybenzaldehyde and 2-ethylhexyl ethanoate was carried out smoothly in the presence of potassium fluoride on alumina, giving only the E isomer in high yield. The optimum conditions were determined.
