achieved. The anomeric ratio of the products was studied based on the main experimental parameters and the activation mode (thermal or microwave). In the second step, aminolysis of the n-octyl ester was achieved with various functionalized primary amines under standard thermal or microwave activation. The physico-chemical properties of these new amphiphilic ligands were measured and these compounds were found
本文描述了由d-半乳糖醛酸和正辛醇(可再生原料)分两步轻松,高效地合成新型络合表面活性剂的方法。第一步,在费歇尔条件下实现了同时的O-糖基化-酯化。根据主要的实验参数和活化方式(热或微波)研究了产物的异头比。第二步,在标准的热或微波活化下,用各种官能化的伯胺实现正辛酯的氨解。测量了这些新的两亲性配体的物理化学性质,发现这些化合物表现出令人感兴趣的表面性质。通过EPR滴定研究了一种被吡啶部分官能化的脲酰胺配体对Cu(II)离子的络合能力。还合成并表征了固体化合物,从光谱数据推导了其相对结构。
