Abstract:
The present invention provides a method for producing a diol having a cyclic acetal skeleton, in which the method include an acetalization reaction step of obtaining a diol having a cyclic acetal skeleton by subjecting raw material hydroxypivalaldehyde and at least pentaerythritol and/or trimethylolpropane to an acetalization reaction under an acid catalyst and the raw material hydroxypivalaldehyde can contain a prescribed amount of at least one impurity selected from the group consisting of formaldehyde, neopentyl glycol, an ester compound having a neopentyl glycol skeleton represented by formula (III), and isobutyraldehyde.

Claim (Index 3):
The method according to  claim 1 , wherein\n in terms of an area fractional concentration based on a sum of components having a relative retention time of 1.45 or less on an assumption that a relative retention time of the diol in gas chromatography analysis performed under prescribed conditions is 1.00, the diol obtained by the acetalization reaction comprises, as an impurity, a hydroxypivalaldehyde neopentyl glycol acetal of formula (II) in an amount of 0.19 area % or less:
