efficient method for the synthesis of longchain 2-alkyl-1-(2-hydroxyethyl)-2-imidazolines, and their amide precursors, by condensing aminoethylethanolamine and several fatty acids under non-solvent microwave irradiation using CaO as support, is described. Products were obtained in good yields and high purity in a few minutes, in both multimode microwave and monomode microwave oven. Evidences of non-thermal
描述了一种合成长链 2-烷基-1-(2-羟乙基)-2-咪唑啉及其酰胺前体的有效方法,通过使用 CaO 作为载体,在非溶剂微波辐射下缩合氨基乙基乙醇胺和几种脂肪酸。 . 在多模微波和单模微波炉中,几分钟内即可获得高产率和高纯度的产品。给出了非热微波效应的证据。
