Dehydration of 1,4-butanediol was investigated over ZrO 2 at temperatures of 325-375 โ€ข C. Modification of ZrO 2 with a small amount of sodium hydroxide greatly enhanced the selectivity to 3-buten-1-ol. Temperature-programmed desorption of adsorbed NH 3 and CO 2 elucidated acidity and basicity of the
