Description
Verfahren zur Herstellung von n-Butenylamin Es wurde gefunden, daß man durch Erhitzen von Salzen des i-Aminobutanols-(3) mit starken Säuren unter Abspaltung von Wasser n-Butenylamin erhält. Geeignete Salze sind beispielsweise solche der Bromwasserstoffsäure, Salzsäure, Phosphorsäure oder Schwefelsäure. Die Umsetzung erfolgt im allgemeinen zwischen etwa 200 und 28o°, vorzugsweise bei 220 bis 25o°. Aus dem entstehenden Salz des n-Butenylamins wird durch basische Stoffe, wie Alkalien, Erdalkalien oder höhersiedende, Amine, das n-Butenylamin in Freiheit gesetzt, das durch Destillation gewonnen werden kann. Bei 8o bis 9o° geht ein Gemisch von Wasser und n-Butenylamin über, das durch Fraktionieren weiter gereinigt werden kann. Beispiel 89o Teile i-Aminobutanol-(3) werden mit etwa iooo Teilen konzentrierter Salzsäure neutralisiert. Das überschüssige Wasser wird abdestilliert und das wasserfreie Chlorhydrat 6 Stunden lang auf 22o bis 23o° gehalten, bis kein, Wasser mehr übergeht. Der Rückstand wird mit y8oo Teilen 5ooloiger Natriumhydroxydlösung verrührt und destilliert. Bei 8o bis 9o° gehen etwa 7oo Teile eins Gemisches von Wasser und Butenylamin über. Durch fraktionierte Destillation kann daraus hochprozentiges Butenylamin gewonnen werden.Process for the preparation of n-butenylamine It has been found that by heating salts of i-aminobutanol- (3) with strong acids with splitting off receives n-butenylamine from water. Suitable salts are, for example, those of the Hydrobromic acid, hydrochloric acid, phosphoric acid or sulfuric acid. The implementation generally takes place between about 200 and 28o °, preferably at 220 to 25o °. The resulting salt of n-butenylamine is converted into basic substances such as alkalis, Alkaline earths or higher-boiling amines, the n-butenylamine set free, the can be obtained by distillation. At 8o to 9o ° there is a mixture of water and n-butenylamine, which can be further purified by fractionation. example 89o parts of i-aminobutanol- (3) are mixed with about 1000 parts of concentrated hydrochloric acid neutralized. The excess water is distilled off and the anhydrous chlorohydrate Maintained at 22o to 23o ° for 6 hours until no more water passes over. The residue is stirred with 500 parts of 5oolo sodium hydroxide solution and distilled. at 8o to 9o ° go about 700 parts of a mixture of water and butenylamine. High-percentage butenylamine can be obtained from it through fractional distillation will.
Man kann mit dem gleichen Erfolg auch mit Schwefelsäure oder Phosphorsäure an Stelle von Salzsäure neutralisieren.One can use sulfuric acid or phosphoric acid with the same success neutralize instead of hydrochloric acid.
