Abstract: Production of neopentyl glycol hydroxypivalate (I) and neopentyl glycol (II) comprises reacting isobutyraldehyde and formaldehyde in the presence of a tertiary amine to form a hydroxypivalaldehyde solution, distilling off low boilers and recycling them to the reaction, separating the bottoms into two streams, hydrogenating one stream to produce (II) and converting the other stream to (I).

Abstract: The invention relates to a method for purifying a polyalcohol of general formula (I) wherein R can be the same or different and can represent a substituted or unsubstituted aliphatic hydrocarbon having 1 - 22 C atoms, an aryl or an arylalkyl group having 6 - 22 C atoms or a methylol group. By treating the polyalcohols of general formula (I) with at least one acid and/or basic ion exchanger, the CPR value can be adjusted from 0 to +1.5.
