The dehydration of 1,3-butanediol was investigated over CeO2–ZrO2 catalysts prepared by impregnation at temperatures of 325–375 °C. Pure CeO2 selectively catalyzed the dehydration of 1,3-butanediol to form 3-buten-2-ol and 2-buten-1-ol, while pure ZrO2, which was less active than pure CeO2, catalyzed the dehydration to 3-buten-1-ol. In the CeO2/ZrO2 catalyst in which CeO2 was supported on zirconia,...
