PROBLEM TO BE SOLVED : To provide a method for selectively manufacturing allyl type unsaturated alcohol form a 1, 3-diol type raw material.
SOLUTION : There is provided a manufacturing method of aimed allyl type unsaturated alcohol by making zirconia having total percentage content of a fluorite type tetragonal crystal and a fluorite type cubic crystal in an X-ray diffraction to diol represented by the formula (1) of 70% or more, containing at least one kind of dopant selected from alkali earth elements and rare earth elements and total content of the dopant atom to 1 mol of zirconium atom of 0.01 to 0.5 mol act and selectively proceeding one molecule dehydration. In the formula, R1 to R4 are each independently H, a C1 to 5 alkyl group or a C6 to 12 aryl group.
