A method for the Recovery of D - Tartaric acid and enantiomerically Pure Essential from a waste stream containing Tartrate salts ded

摘要

Provided is a method for the Recovery of D - Tartaric acid and Pure Essential enantiomu00e9ricamente, from aqueous waste streams yorgu00e1nicos,Generated in the separation of 2 - amino - 2.3 - dimetilbutironitrilo Racemic through the formation and isolation of a monobu00e1sicacristalina Tartrate Salt.Optically Pure D - Tartaric acid recovered can be recycled in an efficient way, to provide a continuous Separation 2 - amino - 2.3 - dimetilbutironitrilo Racemic.
