Abstract

Se encuentra divulgado un paso en el proceso de purificación de los refrigerantes de hidroclorofluoroolefinas que están hechas de los procesos en donde 1,1,3,3 tetracloropropeno (R1230za) o 1,1,1,3,3-pentacloropropano (R240fa) reaccionan con el HF en exceso. El proceso de purificación emplea una reacción a temperatura fría con una base para eliminar el HF y cualquier HCl. El proceso previene un aumento en productos secundarios orgánicos no deseados, especialmente trifluoropropina (TPF) y, simultáneamente, no reduce la cantidad del refrigerante de hidroclorofluoroolefina deseado producido. El proceso también puede tener un paso opcional mediante el cual el refrigerante de hidroclorofluoroolefina y otros productos orgánicos se eliminan de la corriente acuosa del proceso o las corrientes resultantes de la reacción con la base. Los productos orgánicos eliminados pueden ser reciclados. Este paso opcional puede aumentar de manera beneficiosa el rendimiento del refrigerante deseado, mientras disminuye la carga ambiental de la planta, mediante la purificación de las corrientes acuosas del proceso resultantes.
