Procedimiento para la obtención de derivados de
ácido glicin-N,N-diacético
La presente invención se refiere a un
procedimiento para la obtención de derivados de ácido
glicin-N,N-diacético, y a productos
intermedios que se presentan en este procedimiento.
La DE-A 37 12 329 da a conocer un
procedimiento para la obtención de derivados de ácido
serin-N,N-diacético mediante
reacción de una glicina hidroximetilsubstituida con formaldehído y

Era tarea de la presente invención poner a
disposición un procedimiento para la obtención de derivados de ácido
glicin-N,N-diacético, que ya no
presentara los inconvenientes del estado de la técnica.
Correspondientemente se encontró el empleo de
derivados de ácido
glicin-N,N-diacético de la fórmula
general I
en la
que
R representa metilo, etilo,
n-propilo o iso-butilo, y
M significa hidrógeno, metal alcalino, amonio o
amonio substituido, en las correspondientes cantidades
estequiométricas,
que está caracterizado porque se hace reaccionar
ácido iminodiacético o iminodiacetonitrilo con correspondientes
monoaldehídos y cianuro de hidrógeno o cianuro de metal alcalino, y
a continuación se hidrolizan los grupos nitrilo aún presentes para
dar grupos carboxilo.
La citada forma de ejecución constituye un
ejemplo de "síntesis de Strecker", en el que se hacen
reaccionar generalmente aldehídos con amoniaco o aminas y ácido
cianhídrico (variante "ácida") o cianuros (variante
"alcalina") para dar aminoácidos, o derivados de los
mismos.
La variante "alcalina" de la síntesis de
Strecker se presenta, a modo de ejemplo, en la US-A
3 733 355 en forma general. No obstante, los ejemplos indicados en
la misma muestran que siempre se presenta una fracción elevada de
productos secundarios, sobretodo de ácido glicólico indeseable; esto
se puede deducir de las conversiones, de sólo un máximo de
aproximadamente un 89%.
La variante "ácida" de la síntesis de
Strecker es conocida, a modo de ejemplo, por la DE-A
20 27 972. En esta se describe la obtención de
carboximetiliminodiacetonitrilo partiendo de glicina, formaldehído y
ácido cianhídrico en medio ácido. En este caso se recomienda añadir
ácido adicional para mantener el valor de pH en el intervalo por
debajo de 7.
También es tarea de la presente invención poner a
disposición un procedimiento más efectivo y económico para la
obtención de derivados de ácido
glicin-N,N-diacético I, que
suprimiera en especial la formación de productos secundarios
indeseables, y pudiera prescindir de substancias auxiliares
adicionales, a modo de ejemplo para la regulación del valor de
pH.
Se han mostrado especialmente ventajosas las
variantes en las cuales se trabaja con cianuro de hidrógeno
(variante "ácida"). Convenientemente se emplea cianuro de
hidrógeno anhidro, que se maneja habitualmente en esta fórmula a
escala industrial.
La reacción se lleva a cabo preferentemente en
agua, pero también en un disolvente orgánico, o en mezclas de los
mismos. Como disolventes orgánicos se emplean preferentemente
aquellos que son parcial o completamente miscibles con agua, por
ejemplo metanol, etanol, n-propanol,
iso-propanol, terc-butanol, dioxano
o tetrahidrofurano. También se pueden emplear solubilizadores.
Convenientemente se emplea 2 a 2,6 moles de
aldehído por mol de amino compuesto, en forma anhidra o como
disolución acuosa, y 2 a 2,3 moles de cianuro de hidrógeno o cianuro
de metal alcalino, a modo de ejemplo cianuro sódico o potásico. En
el caso de cianuro de hidrógeno anhidro, la reacción se efectúa
normalmente a temperaturas de 0 a 120ºC, en especial 15 a 80ºC, y en
el caso de cianuros de metal alcalino a 40 hasta 110ºC, en especial
70 a 100ºC. Para la reacción con ácido cianhídrico anhidro, en el
caso de empleo concomitante de ácidos minerales, como ácido
sulfúrico, clorhídrico u orto-fosfórico, por regla
general entra en consideración un intervalo de pH de 0 a 11, en
especial de 1 a 9, en el caso de reacción con cianuros de metal
alcalino se trabaja habitualmente a pH 10 a 14, en especial 11 a
13.
A esta reacción sigue una hidrólisis de grupos
nitrilo aún presentes para dar grupos carboxilo, que se lleva a cabo
de modo conocido en sí en medio de reacción acuoso, en presencia de
bases, como hidróxido sódico o potásico, o de ácidos, como ácido
sulfúrico o clorhídrico, a temperaturas de 20 a 110ºC, en especial
40 a 110ºC.
Correspondientemente a las condiciones de
reacción se obtiene los derivados de ácido
glicin-N,N-diacético I, como ácido
carboxílico libre, o a modo de ejemplo como sal metálica alcalina. A
partir del ácido libre se pueden obtener las sales deseadas sin
dificultad, mediante neutralizado con las correspondientes bases, a
modo de ejemplo bases de amina.
Los derivados de ácido
glicin-N,N-diacético I y sus sales
se pueden aislar sin problema en forma pura a partir de sus
disoluciones. En este caso se ofrecen en especial secado por
pulverizado o liofilizado, cristalización y precipitación. Puede ser
ventajoso alimentar directamente a un empleo técnico la disolución
producida en la obtención.
También son objeto de la presente invención los
glicin-N,N-diacetonitrilos y
glicinnitril-N,N-diacetonitrilo
substituidos en posición 2 por el resto R, aún no conocidos, en los
que R representa metilo, etilo, n-propilo o
isobutilo, a modo de ejemplo los compuestos
\alpha-alanin-N,N-diacetonitrilo
y
\alpha-alaninnitril-N,N-diacetonitrilo
como productos intermedios para la obtención de derivados de ácido
glicin-N,N-diacético I, y sus sales.
Estos compuestos se forman como productos intermedios en la reacción
de iminodiacetonitrilo con correspondientes monoaldehídos y cianuro
de hidrógeno.
Generalmente se obtiene el producto de reacción
en rendimiento elevado en forma suficientemente pura. El contenido
en productos secundarios es reducido. Otras ventajas del
procedimiento de obtención según la invención son el régimen exento
de sales, y las substancias de empleo fácilmente disponibles.
Se añaden una suspensión de 95 g de
iminodiacetonitrilo (al 100% en peso) en 500 ml de agua,
sucesivamente a 35 hasta 50ºC, 14 g de ácido sulfúrico (al 100% en
peso), 27 g de ácido cianhídrico anhidro, y 44 g de acetaldehído (al
100% en peso). Se agitó hasta que ya no se pudo verificar ninguna
modificación en la valoración del contenido en ácido cianhídrico.
Tras enfriamiento a 10ºC se separó por filtración y se secó el
precipitado. Resultaron 123,4 g de
\alpha-D,L-alaninnitril-N,N-diacetonitrilo

a continuación se agitó durante 2 horas más a esta temperatura.
Después se calentó durante 10 horas a 95ºC. Hacia el final de la
reacción se diluyó la mezcla de reacción con agua. De este modo se

ácido sulfúrico (al 96% en peso), 180 g de cianuro de hidrógeno (al
99% en peso) y 385 g de aldehído propiónico (al 99,5% en peso), y se
agitó a 35ºC hasta que ya no se pudo verificar una modificación del
contenido con ácido cianhídrico mediante valoración. Tras
enfriamiento a 10ºC se obtuvieron 977 g (97% de la teoría) de
D,L-etilglicin-N,N-diacetonitrilo
como precipitado mediante filtración, con una pureza de un 96,8% en
peso.
Después se introdujo el precipitado en 4430 g de
un hidróxido sódico acuoso al 17% en peso a 60ºC, y se agitó
subsiguientemente 3 h a 60ºC y 10 h a 95ºC, y al final se diluyó con
agua. De este modo se obtuvo 5275 g de una disolución de sal
trisódica de ácido
D,L-etilglicin-N,N-diacético
con un poder enlazante de hierro de 0,985 mmol/g (correspondiente a
un 89% de rendimiento de la teoría).
Se añadieron gota a gota a una suspensión de 95 g
de iminodiacetonitrilo en 550 g de agua, sucesivamente, 14 g de
ácido sulfúrico (al 96% en peso), 26,9 g de ácido cianhídrico (al
99,3%) y 79,3 g de aldehído butírico, y se agitaron 4 h a 35ºC hasta
que ya no se pudo verificar una modificación del contenido en ácido
cianhídrico mediante valoración. Tras enfriamiento a 10ºC se
obtuvieron 165 g (94% del rendimiento de la teoría) de

agitó subsiguientemente 2 h a 95ºC, y a continuación se diluyó con
agua. De este modo se obtuvo 600 g de una disolución de sal
trisódica de ácido
D,L-n-propilglicin-N,N-diacético
con un poder enlazante de hierro de 0,573 mmol/g (correspondiente a

103,4 g de aldehído 3-metilbutírico, y se agitaron 2
h a 35ºC y 3 h a 50ºC hasta que ya no se pudo verificar una
modificación del contenido en ácido cianhídrico mediante valoración.
Tras enfriamiento a 10ºC se obtuvieron 175 g (92% del rendimiento de
