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.

An automatic program synthesizer receives a system specification and searches software parts suited to the specification. In order to obtain a function satisfying the system specification, the searched software parts are corrected or converted in accordance with a knowledge base for customizing a programming form stored therein.
