Procedure

A crude reaction mixture originating from the calcium hydroxide-catalyzed Tishchenko reaction of 375 g of hydroxypivalaldehyde and additionally containing 12 g of water, was treated with 10.2 g of glacial acetic acid at 70° C. and stirred for 10 minutes. 120 g of water were then added, the mixture was stirred at 70° C. for 15 minutes and when phase separation had taken place the lower aqueous phase was separated off. Analytical determination of the salt content of the organic phase gave a value of 1.42% (calculated as calcium acetate).
