摘要:提出了一种通用有效的方法,包括砂磨预处理和蔗糖与脂肪酸甲酯(fame)的碱催化酯交换反应,用于无溶剂合成蔗糖酯.通过以1000 Rpm的转速研磨1小时,获得了具有13μm (d 50)固体颗粒尺寸的亚稳态均质糊剂.该反应混合物使用k 2 Co 3作为催化剂,在135oc下以500 Rpm的搅拌速度搅拌3 H,产生的总硬脂酸甲酯(ms)转化率为91.4%,总se收率为88.2%,而未进行研磨的则d 50153微米)的总蔗糖脂肪酸酯(se)为49.3%,在相同反应条件下的ms转化率为83.1%.反应动力学表明,经过研磨预处理的反应混合物显示出较短的诱导时间和更快的反应速率,从而形成了se.当前研究中se的无溶剂合成的推广可归因于固体颗粒尺寸的减小和固液相兼容性的提高.我们认为,该策略可用作增强有机合成中其他异质反应的一般方法.
