Abstract
Un procedimiento acuoso de fabricación de 2,2''-oxodisuccinato, por reacción de materiales de partida, que comprenden: I Un componente orgánico del material de partida, que comprende maleato; II un componente de catión metálico divalente; y III un componente alcalino; en el que, durante dicho procedimiento, dicho componente orgánico del material de partida se convierte en 2,2''-oxodisuccinato, con rendimientos concretos, y tiende a formarse subproducto, especialmente fumarato; comprendiendo dicho procedimiento acuoso las siguientes etapas: A. seleccionar los materiales de partida, que comprenden: I un componente orgánico, que comprende maleato y malato previamente formado, a una relación en moles de maleato: malato en el intervalo de 0,7:1 a 2,0:1; II un componente de catión metálico divalente, seleccionado entre calcio, magnesio y sus mezclas, a una relación en moles de componente de catión divalente : componente orgánico en el intervalo de 0,1:1 a 0,95:1; III un componente alcalino, seleccionado entre hidróxido y aniones que forman hidróxido; y, adicionalmente, IV un componente de catión monovalente solubilizante, seleccionado entre sodio, potasio y sus mezclas, a una relación en moles de sodio: potasio en el intervalo de 1,0:0,0 a 0,9:0,1; y B. llevar a cabo la reacción en una mezcla acuosa alcalina, fluida, de dichos materiales de partida, que tiene las siguientes concentraciones netas en peso: no más de 75% de agua; al menos 0,0001% del componente alcalino III, expresado como exceso de hidróxido neto; al menos 1% del componente IV de catión monovalente solubilizante; teniendo lugar dicha reacción a una o más temperaturas en el intervalo de 20ºC a 110ºC; y C. detener la reacción; caracterizado por una duración total de la reacción comprendida entre 12 horas y 400 días; el tiempo total a cualquier temperatura superior a 100ºC no excede de 1,5 horas; el tiempo total a cualquier temperatura superior a 90ºC no excede de 4,5 horas; el tiempo total a cualquier temperatura superior a 80ºC no excede de 13,5 horas; el tiempo total a cualquier temperatura superior a 70ºC no excede de 1,7 días; el tiempo total a cualquier temperatura superior a 60ºC no excede de 5,1 días; el tiempo total a cualquier temperatura superior a 50ºC no excede de 15 días; el tiempo total a cualquier temperatura superior a 40ºC no excede de 46 días; y el tiempo total a cualquier temperatura superior a 30ºC no excede de 137 días; con ello se minimiza la formación de subproducto y se obtiene un rendimiento de 2,2''-oxodisuccinato de 80% o mayor.
