  • Publication number: 20030009061
    Abstract: The invention is a preparation process of alkylcyclohexanol alkylene oxide adduct which contains almost no alkylphenol alkylene oxide adduct 1) in the absence of a solvent, 2) in the presence of a saturated hydrocarbon solvent, or 3) in the presence of water.
    Type: Application

  • Patent number: 6437194
    Abstract: The invention is a preparation process of alkylcyclohexanol alkylene oxide adduct which contains almost no alkylphenol alkylene oxide adduct 1) in the absence of a solvent, 2) in the presence of a saturated hydrocarbon solvent, or 3) in the presence of water. The invention can prepare alkylcyclohexanol alkylene oxide having a 200 ppm or less content of alkylphenol and alkylphenol alkylene oxide adduct. The alkylcyclohexanol alkylene oxide adduct obtained in the process of the invention has less ultraviolet absorption and fluorescence due to alkylphenol alkylene oxide adduct and is thus useful for spectrometric analysis of protein and further has excellent properties in the field of detergent and other common uses of surface active agents.
