The synthesis of lactic acid from 1, 1-dichloroacetone (DCA) was studied. Lactic acid was prepared by the hydrolysis of DCA with active charcoal powder catalyst under the milder conditions, H2O : DCA (mol ratio) =25 : 1, 180°C, in comparison with the reaction without catalyst. Alternatively, lactic acid was prepared by the alkali-acid treatment of DCA in 9397% yield. 2-Chloropropionic acid (CPA) was not detected in the reaction mixture and lactic acid was not yielded under the similar conditions. It seems that the intermediate in the lactic acid formation from DCA is not CPA, but a ketoaldehyde as cited in literatures.
