diethanolammonium (DEA) salts of carboxylic acids have been synthesized and identified using a complex of physicochemical methods (NMR, FT-IR spectroscopy, elemental, thermal analysis). The crystal structure of diethanolammonium salts of benzoic and 2-hydroxy-1-naphthoic acids was determined for the first time by XRD. A comparative analysis of the conformations of DEA cations was carried out. The effectiveness
已经合成并使用一系列物理化学方法(NMR、FT-IR 光谱、元素、热分析)鉴定了 15 种基于羧酸的二乙醇铵 (DEA) 盐的新型质子离子液体。通过XRD首次确定了苯甲酸和2-羟基-1-萘甲酸的二乙醇铵盐的晶体结构。对 DEA 阳离子的构象进行了比较分析。合成的 DEA 离子液体作为缓冲剂的有效性在68 次Ga 放射性标记反应中与不同的螯合剂和临床批准的肽进行了证明。
