ABSTRACT:
The invention relates to a method for preparing a complex of an organic amine and lactic acid in a reactor, characterized in that a water-miscible organic amine is brought into contact with magnesium lactate in an aqueous medium in the reactor to form the complex and precipitated magnesium hydroxide, after which the magnesium hydroxide is separated from the complex.
