A process for producing lactic acid and barium hydroxide from barium lactate is provided. The process comprises (a) reacting barium lactate with an acid selected from the group consisting of hydrochloric acid and nitric acid, to produce lactic acid and inorganic barium salt comprising barium chloride and/or barium nitrate; and(b) reacting the inorganic barium salt with a hydroxide in the presence of water to produce solid barium hydroxide; wherein the hydroxide is selected from the group consisting of sodium hydroxide, lithium hydroxide, potassium hydroxide and ammonium hydroxide. Also provided are processes for the production of alkyl lactate, oligomeric lactic acid, lactide and poly-lactic acid. |
