Preparation and properties of isomeric decahydrol polyoxyethylene ether
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.
