Abstract
Un método para eliminar oxígeno disuelto a partir de agua alcalina que contiene oxígeno disuelto a una temperatura mayor de 121.11sC (250sF), el cualcomprende la etapa de agregar al agua alcalina que contiene oxígeno disuelto una cantidad efectiva dedepurador o eliminador de oxígeno de una semicarbazidasoluble en agua de la formula I en donde R1 y R2 se seleccionan del grupo que consiste de los grupos alquilo C1-10, cicloalquilo, arilo, cicloalquiloxi,alquiloxi. Los materiales preferidos son 4-fenilsemicarbazida, 4-isopropilsemicarbazida, 4,4-dietilsemicarbazida y carbazoilmorfolina. También se requiere uncatalizador por debajo de 204.44sC (400sF).
