摘要
以异构十醇与环氧乙烷为原料,通过改变环氧乙烷比例制备不同EO比例的异构十醇聚氧乙烯醚IC10EO3、IC10EO6、IC10EO9,采用红外光谱(FT-IR)和质谱对其结构进行表征.对比研究了EO比例对异构十醇聚氧乙烯醚表/界面活性、接触角、润湿渗透性能、泡沫性能和清洗性能的影响.结果表明:制备的3种异构十醇聚氧乙烯醚具有较高的表面活性,静态表面张力分别为27.69、27.72、27.17 mN/m.对于帆布片和金属板材,IC10EO3、IC10EO6表现出良好的润湿性能,且具有良好的消泡性能和清洗能力.
Abstract
Isomeric decanols and ethylene oxide were used as raw materials,and isomeric decahydrol polyoxyethylene ethers with different EO ratios,IC10EO3,IC10EO6 and IC10EO9 were prepared by changing the ra-tio of ethylene oxide.The structures of these polyoxyethylene ethers were characterized by infrared spectros-copy(FT-IR)and mass spectrometry.The effects of EO ratio on the surface/interfacial activity,contact angle,wetting and penetration properties,foam properties and cleaning properties of the isomeric decahydric alcohol polyoxyethylene ethers were also comparatively investigated.The results showed that the three prepared iso-meric decahydric alcohol polyoxyethylene ethers had high surface activity,and the static surface tension was 27.69,27.72 and 27.17 mN/m,respectively.IC10EO3 and IC10EO6 exhibited good wetting properties for canvas sheets and metal plates,and had good defoaming properties and cleaning ability.
