摘要: 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.

摘要: A process is provided for the stabilization of polychlorinated alkanes against dehydrochlorination. The process comprises adding a phenol compound to a polychlorinated alkane such that the dehydrochlorination of the polychlorinated alkane is suppressed when heated in the presence of iron (III). In a preferred embodiment, the process comprises the prevention or reduction of dehydrochlorination of 1,1,1,3,3-pentachloropropane when heated in the presence of iron (III) contamination by the addition of monomethyl ether hydroquinone. In another embodiment, the long term storage stability of polychlorinated alkanes against dehydrochlorination is improved due to the addition of a phenol compound.
