肉豆蔻酸和棕榈酸酸盐体系的振动光谱研究

Vibrational Spectroscopic Studies on the Acid Salts of Myristic Acid and Palmitic Acid

报道了肉豆蔻酸和棕榈酸酸盐体系的振动光谱．结果表明，脂肪酸与其碱金属盐之间通过氢键和羧基配位形成酸盐络合物．酸盐体系中氢键具有不同于普通氢键的性质．本文结合振动光谱讨论了酸盐的结构和氢键性质．

Fatty acids and their alkali soaps were well known as the biosurfactants in living system,however,little work had been published on the fatty acid-soap complexes,which were suggested here to have some unusual structures and properties.The acid sodium salts and acid potassium salts in molar ratio of 1:1 of both myristic acid and palmitic acid were investigated by FTIR and FT-Raman spectroscopies. The spectral results showed that very strong hydrogen bonds existed in these long-chain acid salts. In this paper,the possible structures of acid soaps were discussed according to spectroscopic data.
