Abstract

On fait réagir l'éthylène-diamine et un halogénure d'éthyle à un rapport molaire d'environ 1 à 20 : 1 et à une température comprise entre -10 et +120 degrés C en présence d'environ 0 à 50 % en poids d'eau, on neutralise le mélange de réaction obtenu par contact avec une solution aqueuse contenant d'environ 1 à 2 équivalents molaires d'un agent alcalinisant minéral, par rapport à l'halogénure d'éthyle, on sépare la couche aqueuse de la couche organique neutralisée et on ajoute à cette dernière une proportion d'environ 0,2 à 100 % de son poids d'un solvant hydrocarboné aliphatique, on élimine par distillation fractionnée azéotropique toute l'eau et toute l'éthylène-diamine et on soumet le résidu à distillation fractionnée au cours de laquelle on sépare le solvant hydrocarboné résiduel et on recueille la N-éthyléthylène-diamine à une pureté supérieure à 99 % environ.Ethylenediamine and an ethyl halide are reacted at a molar ratio of about 1 to 20: 1 and at a temperature of -10 to +120 degrees C in the presence of about 0 to 50% by weight. of water, the reaction mixture obtained is neutralized by contact with an aqueous solution containing about 1 to 2 molar equivalents of an inorganic basifying agent, relative to the ethyl halide, the aqueous layer is separated from the neutralized organic layer and a proportion of about 0.2 to 100% of its weight of an aliphatic hydrocarbon solvent is added to the latter, all the water and all the ethylene diamine are removed by fractional azeotropic distillation and all the ethylene diamine is subjected to the residue to fractional distillation during which the residual hydrocarbon solvent is separated and the N-ethylethylene-diamine is collected in a purity greater than about 99%.
