Abstract:
A process for the resolution of (D,L)-carnitinamide (D,L-I) chloride in its enantiomers (D-I) and (L-I), characterized in that a supersaturated solution or suspension of (D,L-I) in a suitable solvent or mixture of solvents, optionally added with a surfactant, is used. A series of alternate preferential crystallizations is carried out after adding minimum amount of seeds of one of the two enantiomers, (D-I) or (L-I), that is to be precipitated, and subsequently restoring the supersaturation conditions by adding an appropriate amount of (D,L-I) racemate.
