| Abstract: | A novel synthetic route that directly inserts ethylene oxide into butyl acetate without any labile hydrogen to produce oligo‐ethylene glycol butyl ether acetates is developed using an efficient acid–base bifunctional catalyst. The layered double hydroxide materials, which have structures similar to that of hydrotalcite, are synthesized using co‐precipitation methods. After modification by organic acid, the as‐prepared catalysts exhibit higher butyl acetate conversion and ethylene oxide catalytic activity with narrow ethylene glycol butyl ether acetate adduct distribution.
