  • Publication number: 20230348352
    Abstract: A method of synthesizing anhydrous lactic acid is provided by reacting a compound of formula (Ia): with an acid compound of formula HnX in a first solvent to produce a reaction mixture comprising a compound of formula (Ib) and a lactic acid compound of formula (I) in solution with the first solvent and/or water. n is an integer other than 0, x is 0, or an integer other than 0, M is an alkali metal or alkaline earth metal and X is the conjugate base of the acid compound of formula HnX. The resulting reaction mixture is filtered to produce a filtrate containing lactic acid in solution. The filtrate is crystalized from a second solvent to produce anhydrous lactic acid.
