Abstract
LA INVENCION SE REFIERE A UNA VIA ALTERNATIVA PARA PRODUCIR BENZOFENONAS QUE ES SELECTIVA Y EVITA LOS PROBLEMAS DE LOS METODOS PREVIOS QUE EMPLEAN, POR EJEMPLO, GRANDES CANTIDADES DE UN CATALIZADOR DE CLORURO DE ALUMINIO O ACIDO NITRICO. EN ESTE PROCESO, SE OXIDA FOTOLITICAMENTE DIFENIL METANO (DFM) COMO MATERIAL DE PARTIDA EN FASE HIDROFOBA, PONIENDOLO EN CONTACTO CON UNA FASE ACUOSA QUE CONTIENE MAS DE 1 MOL DE HBR Y POR LO MENOS 1,5 MOLES DE H2O2, POR MOL DE DFM, SIENDO LA RADIACION CAPAZ DE DISOCIAR EL BROMO EN SUS RADICALES, Y ESPECIALMENTE DE LONGUITUD DE ONDA DE 600 A 250 MM. SE EMPLEA UNA TEMPERATURA DE REACCION DE 50 A 65 (GRADOS) C Y EL DISOLVENTE ES UN HIDROCARBURO O CLOROHIDROCARBURO DE PUNTO DE EBULLICION ADECUADO. EL H2O2 SE INTRODUCE PROGRESIVAMENTE EN LA MEZCLA DE REACCION. LAS BENZOFENONAS SE RECUPERAN PRINCIPALMENTE EN LA FASE ORGANICA, MIENTRAS QUE LA MAYORIA DEL BROMO / BROMURO ES RETENIDO EN LA FASE ACUOSA Y PUEDE SER VUELTO A EMPLEAR EN UNA OXIDACION SUBSIGUIENTE DE DFM, DESPUES DE RESTAURAR EL BROMURO A SU CONCENTRACION INICIAL. EN UNA MODIFICACION DEL PROCESO SE EMPLEAN PROPORCIONES MOLARES DE BROMURO: H2O2 : DFM DE 1 : 1 : 1 Y UNA TEMPERATURA DE REACCION DE 35%, OBTENIENDOSE DFM SUSTITUIDO CON UN SOLO ATOMO DE BR, EN LUGAR DE SER OXIDADO A BENZOFENONA.
