• acid-base bifunctional catalysts

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.
