摘要： Disclosed is a process for preparing DL-serine, which comprises synthesizing DL-serine according to Strecker reaction with use of a cyan compound, ammonium chloride, ammonia and a reaction substrate comprising glycol aldehyde,
wherein the Strecker reaction is carried out under the reaction conditions of:
molar ratios of the starting materials of:
glycol aldehyde/cyan compound: more than 1.0 and not more than 1.50
ammonium chloride/glycol aldehyde: more than 1.0 and not more than 2.0
ammonium/cyan compound: 1.0 to 7.0
reaction temperature: 20 to 80 °C
reaction time: 15 to 120 minutes,
and the reaction product obtained is hydrolyzed.
Disclosed is also a process for separation and purification of DL-serine produced in the above by subjecting the aqueous solution containing DL-serine alkali salt obtained to ion exclusion chromatography by use of a strongly acidic cation exchange resin, neutralizing the fractionated DL-serine fractions to near the isoelectric point of DL-serine and subjecting the neutralized product to ion exclusion chromatography with a strongly acidic cation exchange resin.

摘要： Disclosed is a process for recovery of amino acids from aqueous mixtures. In particular, it relates to a treatment of said amino acid containing aqueous mixture prior to extraction of the amino acid with a water immiscible organic solution containing a water insoluble extractant for said amino acid. The overall process of the invention which includes the pretreatment and extraction, also includes optional methods of recovering said extracted amino acid from the water immiscible organic solution. Accordingly, the invention also relates to a process for recovery of the amino acid by stripping of the amino acid from the organic solution and precipitation of the amino acid.

摘要： Wäßrige Lösungen freier neutraler α-Aminocarbonsäuren werden aus wäßrigen Lösungen ihrer Alkalimetallsalze dadurch gewonnen, daß man zwei gleich große mit einem stark sauren Kationenaustauscher in der H⁺-Form gefüllte Austauschersäulen einsetzt, den Auslauf der ersten Säule mit dem Kopf der zweiten Säule verbindet, auf den Kopf der ersten Säule zunächst die Lösung des Alkalimetallsalzes aufgibt, anschließend durch Aufgabe von Wasser die um die am Austauscher adsorbierten Alkalimetall-Kationen verminderte Restlösung auf die zweite Säule verdrängt, am Auslauf der zweiten Säule zunächst einen produktfreien Vorlauf abtrennt und, wenn im Ablauf aus der zweiten Säule freie α-Aminocarbonsäure auszutreten beginnt, die Vorlage wechselt und auf den Kopf der ersten Säule weiter solange Wasser aufgibt, bis sich in der Vorlage ein Misch-pH-Wert zwischen 5 und 7 eingestellt hat, die bisher erste Säule abkoppelt und regeneriert, die bisher zweite Säule als nunmehr erste Säule an eine frisch regenerierte Säule als zweite Säule ankoppelt und den ganzen Vorgang beliebig oft wiederholt.

摘要： An improvement in the process of extraction of amino acids from aqueous solutions in which the amino acids are extracted with quaternary ammonium extractants. A pretreatment of the amino acid containing aqueous solution with a tertiary amine prior to extraction of the amino acids with the quaternary ammonium extractant, removes some impurities or poisons present therein, leaving the amino acids in the aqueous solution for subsequent extraction with a water insoluble quaternary ammonium extractant. After extraction with the quaternary extractant, the organic phase is stripped of amino acid and the stripped organic is subjected to an acidic scrub before returning to the quaternary extraction stage.
