Procedure

The procedure described in Example 1 was followed except that 7.57 g of a 70% solution of ammonium lactate was combined with 50 g tributyl phosphate. The reaction mixture was heated for 0.5 hour at 110–118° C. and a reduced pressure of 4.5–5.5 mm Hg, resulting in a conversion of about 97% from ammonium lactate to lactic acid.

Workup

  1. temperatureThe reaction mixture was heated for 0.5 hour at 110–118° C.
