Beschreibung
Zusammenfassung:	Neopentyl glycol hydroxypivalate is isolated from a reaction mixture obtained from a Tishchenko reaction of hydroxypivalaldehyde in the presence of calcium hydroxide, barium hydroxide or strontium hydroxide, by adding acid, removing the salts formed by adjusting the water content in the reaction mixture to 20-60% and extracting the salts at above 50 DEG C. and working up the residual mixture by distillation.
