超支化环氧的合成，收率一直上不去，怎么办? 反应条件是合成羧酸环氧的，做醇肯定做不出，甚至那5%的纯度也难说 这个是原文中，使用我图片中的反应物的反应条件：17 (35.3 g, 249 mmol), triol 11 (10 g, 83 mmol),and tetra-n-butylammonium chloride (3.45 mg,12.5 mmol) were combined and stirred at 120 °cas a homogeneous solution in a closed flask. themixture was stirred for 118 h at this temperature,and the flask was removed from the heating bath.the polymer product was dissolved in thf (20ml) and fractionated into water (750 ml). thewater was decanted, and then the polymer wasdissolved in thf, dried over mgso4, and concentrated in vacuo with stirring to obtain a viscousliquid (27.2 g, 60%).ftir (n): 3380 (br, oh), 2934, 2859, 2409,2290, 1460, 1365, 1106, 1053, 846 cm21. mw5 7300; mn 5 2050; mp 5 3100; pdi 5 3.5. tg。请问这个反应条件又怎么成了羧酸环氧，不太懂，之前一直是做化工的， 查看更多
