Abstract

EL ACIDO METACRILICO PUEDE OBTENERSE VENTAJOSAMENTE, POR OXIDACION EN FASE GASEOSA DE METACROLEINA O ALDEHIDO ISOBUTIRICO EN CATALIZADORES CONTENIENDO MO Y P A 250 A 400 GRADOS C BAJOENFRIAMIENTO DEL GAS DE REACCION CALIENTE POR DEBAJO DE 100 GRADOS C, ABSORCION DEL ACIDO METACRILICO EN UNA COLUMNA DE ABSORCION CON AGUA A TEMPERATURAS IFERIORES A 100 GRADOS C Y REINCORPORACION PARCIAL A UN REACTOR DE OXIDACION DESPUES DE MEZCLA DE METACROLEINA O ALDEHIDO ISOBUTIRICO Y OXIGENO, SI AL GAS DE ESCAPE DE REACCION SE AÑADE BAJO DOS TERCIOS DE LA COLUMNA DE ABSORCION UNA CANTIDAD DE METACROLEINA OLDEHIDO ISOBUTIRICO QUE ES IGUAL A LA CANTIDAD NECESITADA EN LA REACCION DE METACROLEINA O ALDEHIDO ISOBUTIRICO, JUNTO CON INHIBIDORES DE POLIMERIZACION EN FORMA LIQUIDA Y SE SEPARA DEL GAS DE ESCAPE POR DEBAJO DEL PUNTO DE ENTRADA DE LA METACROLEINA FRESCA O ALDEHIDO ISOBUTIRICO O DESPUES DE LA COLUMNA DE ABSORCION UNA CORRIENTE Y LA METACROLEINA NO TRANSFORMADA O ALDEHIDO ISOBUTIRICO SE PASAN POR UNACOLUMNA DE LAVADO CONAGUA A TEMPERATURA DE 10 GRADOS C Y SE OBTIENEN COMO SOLUCION ACUOSA EN LA CEBEZA DE LA COLUMNA DE ABSORCION.
