Abstract

La presente invención se refiere a procesos para reducir la concentración de impurezas de RfC=CX en fluoroolefinas. El proceso incluye: poner en contacto una mezcla que comprende al menos una fluoroolefina y al menos una impureza de RfC=CX con al menos una amina para reducir la concentración de la por lo menos una impureza de RfC=CX en la mezcla; en donde Rf es un grupo alquilo perfluorado, y X es H, F, C1, Br o I. La presente invención también se refiere a procesos para la fabricación de al menos un producto de hidrotetrafluoropropeno seleccionado del grupo que consiste en CF3CF=CH2, CF3CH=CHF, o al menos un producto de hidrotetrafluoropropeno seleccionado del grupo que consiste en CF3CC1=CH2, CF3CH=CHC1, y mezclas de los mismos, y reducir la concentración de la impureza de CF3C=CH generada durante los procesos.
