Process for production of alkylene oxide adducts |
| abstract |
The present invention relates to a process for producing an alkyleneoxide adduct, including the steps of reacting an aliphatic alcohol containing a hydrocarbon group having 6 to 22 carbon atoms with an alkyleneoxide in the presence of a catalyst to obtain a reaction product containing an alkyleneoxide adduct; and subjecting the reaction product successively to acid treatment and reduction treatment, and an alkyleneoxide adduct having a carbonyl value of 5 μmol/g or less. The alkyleneoxide adduct is useful as a raw material of various anionic surfactants, and the anionic surfactants derived from the alkyleneoxide adduct are free from undesirable coloration. |
