Abstract

Se suministra un procedimiento para la recuperacion de ácido D-tartárico esencial y enantioméricamente puro, a partir de flujos de desechos acuosos yorgánicos, generados en la separacion del 2-amino-2,3-dimetilbutironitrilo racémico, por medio de la formacion y aislamiento de una sal de tartrato monobásicacristalina. El ácido D-tartárico optimamente puro recuperado, puede ser reciclado en forma eficiente, para suministrar una separacion continua del2-amino-2,3-dimetilbutironitrilo racémico.A procedure is provided for the recovery of essential and enantiomerically pure D-tartaric acid, from streams of aqueous and inorganic wastes, generated in the separation of racemic 2-amino-2,3-dimethylbutyronitrile, through the formation and isolation of a monobasic crystalline tartrate salt. The optimally pure D-tartaric acid recovered can be efficiently recycled to provide a continuous separation of racemic 2-amino-2,3-dimethylbutyronitrile.
