Process for extraction separation of l-phosphinothricin and L-glutamic acid in aqueous solution.

摘要

A large number of processes USUAL FOR THE SEPARATION OF AMINO FAIL IF AMINOACIDOS highly polarized Hydrophilic should be separated with isoelectric points (IEP) are very close. BLENDED L-Glutamic acid (IEP = 3.24) and L-FOSFONOTRICIN (IEP = 2.6) TO BE PRESENTED IN THE RELEVANT TRANSAMINIZACION enzymatic (ALFA) -propionic ketonic, they have until now been very difficult to separate. THE OBJECT OF THE INVENTION THIS IS A PROCESS FOR THE SEPARATION OF L-phosphinothricin and L-Glutamic acid SUCH feature separation is performed as liquid-liquid extraction WITH TWO PHASES AQUEOUS immiscible AS SYSTEM PHASES IN WHICH IS CONTAINED a combination as shaper PHASE IN THE SYSTEM PHASES OF AT LEAST TWO-soluble polymers other water or at least one water-soluble salt and a polymer sOLUBLE ALSO IN WATER AND EXTRACTION IN VARIOUS STAGES countercurrent PERFORMED BY THE PRINCIPLE OF DISTRIBUTION DIJCK.
