多缩乙二醇桥连二对羟基苯甲醛缩邻氨基苯甲酸的合成

Syntheses of Polyethylene Glycol Bridged Diparahydroxylbenzaldehyde Condensed Ortho-Aminobenzoic Acid

以多缩乙二醇桥连二芳醛与邻氨基苯甲酸的缩合合成了4种以对羟基苯甲醛、β—型氨基酸Schiff碱为端基的开链冠醚,并用IR、1HNMR和MS谱,确证了它们的结构。初步实验了其与金属离子的络合性能。

Four open chain crown ethers using parahydroxylbenzaldehyde,β-aminoacid schiff base as end group were snythesized by the condensation of polyethylene glycol bridged diarylaldehyde with orthoaminobenzoic acid.The newly-compounds were characterized by IR,1 HNMR and MS.The complexing ability between open chain crown ethers and metal ion was experimented preliminarily.
