RESOLUTION SYSTEM |
摘要 |
The invention relates to a process for the kinetic resolution of D,L-racemic mixtures of racemates crystallizing as conglomerates. Resolution is effected from supersaturated solutions of these which is carried out in the presence of a polymer bound inhibitor of crystallization of the one form, resulting in the preferred crystallization of the one form, and when the other form is desired - in the presence of such inhibitor for the other form. Amongst racemic mixtures amenable to this process are amino acids. The process can be carried out in a two-compartment device, where the compartments are separated by a membrane which is permeable to the constituents of the racemate, while it is impervious to the polymer-bound inhibitor for the crystallization of one of the racemic forms. |
