Zur Darstellung von Erucasäure aus Rüböl mit Hilfe der Tieftemperatur‐Kristallisation

Abstract: Bei der Tieftemperatur-Kristallisation von Rubolfettsauren bzw. deren Methylestern aus acetoniger Losung kann unter aus. gewahlten Bedingungen Erucasaure in einer Fraktion bereits bis zu einem Gehalt von iiber 95O/o angereichert werden. Aus diesem Rohprodukt ist eine Reindarstellung durch wiederholte Fraktionierung auf dem gleichen Wege moglich. Die Ausbeuten liegen, bezogen auf die eingesetz te Menge an Gesamtfettsauren bzw. Methylestern, bei etwa 200/0. Der Aufarbeitung der Fettsauren ist aus technischen Gri… Show more

“…The ethanol/FFA ratio was subsequently increased gradually to 6 mL/g of FFA, at which point white crystals formed rapidly. Low-temperature crystallization procedures employing aqueous and nonaqueous solvents in conjuction with other methods have been reported for the preparation of erucic acid from rapeseed oil (11)(12)(13). However, satisfactory recoveries of pure erucic acid were not obtained.…”

“…However, satisfactory recoveries of pure erucic acid were not obtained. The methyl ester of erucic acid was crystallized once from aqueous acetone at temperatures less than 20°C, giving no more than 20% recovery of 95% pure erucic (12). Direct crystallization of the mixed acid soaps from 90% methanol followed by three recrystallizations at 15°C produced crystals with better than 90% erucic acid.…”
