臭氧化合成聚乙二醇醛基衍生物
Synthesis of Polyethylene Glycol Aldehyde Derivatives by Ozonation
摘要
Abstract
Methoxypolyethylene glycol olefin was obtained by olefination of methoxypolyethylene glycol, and followed by ozonation to give methoxypolyethylene glycol aldehyde derivative. The properties of products were characterized by nuclear magnetic resonance spectroscopy (NMR) and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) . The results show that the product has high purity and no by-products. The yields of methoxy polyethylene glycol acetaldehyde and polyethylene glycol propionaldehyde are as high as 98% and 99%, respectively, and the degrees of substitution are 90. 87% ~99. 91% and 98% ~ 100%, respectively.关键词
