Title (EN) METHOD FOR THE PREPARATION OF AMINO-CETONITRILES
(FR) PROCEDE POUR LA PREPARATION D'AMINO-CETONITRILES
Abstract: front page image
(EN)The compounds having the formula (I), wherein R is: -H, -CH¿2?CN, -CH¿2?CH¿2? -N(CH¿2?CN)¿2?, -CH¿2?CH¿2?-N(CH¿2?CN)-CH¿2?CH¿2?-N(CH¿2?CN)¿2? or -CH¿2?CH¿2?-NH-CH¿2?CH¿2?-NH-N(CH¿2?CN)¿2? are prepared by reacting ammonia ethylenediamine or diethylenetriamine with the formaldehyde and the cyanhydric acid. The process is characterized in that, as catalyst, aminoacetic acid is used which is also used for the preparation of acetonitrile of formula I. Aminoacetic acid has the formula (II), wherein R' is: -H, -CH¿2?COOH, -CH¿2?CH¿2?N(CH¿2?COOH)¿2?, -CH¿2?CH¿2?-N(CH¿2?COOH)-CH¿2?CH¿2?-N(CH¿2?COOH)¿2? or -CH¿2?CH¿2?-NH-CH¿2?CH¿2?-N(CH¿2?COOH)¿2?.
(FR)Les composés répondant à la formule (I), dans laquelle R signifie: -H, -CH¿2?CN, -CH¿2?CH¿2?-N(CH¿2?CN)¿2?, -CH¿2?CH¿2?-N(CH¿2?CN)-CH¿2?CH¿2?-N(CH¿2?CN)¿2? ou -CH¿2?CH¿2?-NH-CH¿2?CH¿2?-N(CH¿2?CN)¿2? sont préparés par réaction d'ammoniac, d'éthylène diamine ou de diéthylènetriamine avec le formaldéhyde et l'acide cyanhydrique. Le procédé est caractérisé en ce qu'on utilise comme catalyseur l'acide aminoacétique également employé pour la préparation de l'acétonitrile de formule I. L'acide aminoacétique répond à la formule (II), dans laquelle R' signifie: -H, -CH¿2?COOH, -CH¿2?CH¿2?N(CH¿2?COOH)¿2?, -CH¿2?CH¿2?-N(CH¿2?COOH)-CH¿2?CH¿2?-N(CH¿2?COOH)¿2? ou -CH¿2?CH¿2?-NH-CH¿2?CH¿2?-N(CH¿2?COOH)¿2?.
