Abstract: PROBLEM TO BE SOLVED: To provide a method for easily and economically producing an 1,3-diol. SOLUTION: This method comprises the following steps: (a) at least one kind of >=3C alkanal is prepared, (b) the alkanal is heat-treated in the absence of a basic catalyst, (c) the resultant aldol addition product is hydrogenated, and (d) the objective 1,3-diol thus produced is collected. This 1,3-diol has >=6 carbon atoms in the molecule.
