Abstract
EN UN PROCESO PARA LA OBTENCION DE BROMO-NITRO-ALCOHOLES POR BROMACION DE SALES ALCALINAS O ALCALINO-TERREAS DE NITRO- ALCOHOLES DEBIA QUE TRABAJARSE A ESCALA TECNICA CON CONCENTRACIONES ALTAS. ESTO SE CONSIGUIO BOMBEANDO EN EL CIRCUITO UNA MEZCLA DE BROMO Y DE UNA SOLUCION ACUOSA DE ACIDO BROMHIDRICO A TRAVES DE UN INTERCAMBIADOR DE CALOR, AÑADIENDO LAS DOSIS DE SOLUCION DE LA SAL ALCALINA O ALCALINO-TERREA ANTES DEL INTERCAMBIADOR DE CALOR A UNA VELOCIDAD TAL QUE LA TEMPERATURA MAXIMA DE REACCION NO SUPERE LOS 30 (GRADOS) C.
