Abstract

Procedimiento de separación de una mezcla acuosa de trioxano y formaldehído y aplicaciones correspondientes. La mezcla acuosa de trioxano y formaldehído tiene una primera relación trioxano:formaldehído, y el procedimiento comprende una etapa de reacción de la mezcla acuosa de trioxano y formaldehído con urea y una etapa de separación de una fase gaseosa de salida que tiene una segunda relación trioxano:formaldehído que es superior a la primera relación trioxano:formaldehído. Posibles aplicaciones del procedimiento son para la separación de una mezcla acuosa de trioxano y formaldehído procedente de un reactor en cuyo interior tiene lugar la síntesis de trioxano o procedente de una columna de destilación en cuyo interior se separa una mezcla acuosa previa de trioxano y formaldehído del exceso de formaldehído. Otra posible aplicación es para la obtención de materia prima para la fabricación de colas o resinas de urea-formaldehído.
