Abstract
PROCEDIMIENTO PARA PREPARAR DIOXIDO DE TITANIO DE LA VARIEDAD RUTILO QUE TIENE UN TAMAÑO DE PARTICULA UNIFORME, EN DONDE EL PIGMENTO SE FORMA POR REACCION DE UNA MEZCLA DE UN GAS OXIDANTE Y UN HALURO DE TITANIO, EN FASE VAPOR, A TEMPERATURAS ELEVADAS, EN PRESENCIA DE UN COMPUESTO QUE CONTIENE IONES METALICOS. LA MEJORA COMPRENDE INTRODUCIR EL COMPUESTO QUE CONTIENE IONES METALICOS EN UN REACTOR DE OXIDACION EN FASE VAPOR QUE CONTIENE LA MEZCLA DE REACCION EN AL MENOS DOS INCREMENTOS SEPARADOS. EL PRIMER INCREMENTO SE INTRODUCE EN EL REACTOR EN UN PUNTO CON ANTERIORIDAD A LA REACCION DE DICHA MEZCLA, MIENTRAS QUE EL SEGUNDO INCREMENTO SE INTRODUCE EN EL REACTOR EN UN PUNTO EN DONDE AL MENOS EL 20% DEL REACTANTE TOTAL DE HALURO DE TITANIO SE HA CONVERTIDO AL PIGMENTO DESEADO DE DIOXIDO DE TITANIO.
