Procedure

The procedure described in Example 1 was followed except that the reaction solution consisted of 30 g of a 70% solution of ammonium lactate and 70 g dodecanol. The reaction mixture was heated for 1.5 hours at 105–110° C. and a reduced pressure of 1.1–2.2 mm Hg, resulting in a conversion of about 88% from ammonium lactate to lactic acid. Some of the dodecanol also reacted with lactic acid to form an ester. The conversion from ammonium lactate to lactic acid plus lactic acid ester was about 96%.
