Abstract

SE PRESENTA UN PROCESO CONTINUO PARA LA ACILATACION O ALQUILATACION DE COMPUESTOS AROMATICOS EN FLUORURO DE HIDROGENO. EL COMPUESTO AROMATICO ES LO SUFICIENTEMENTE INSOLUBLE EN FLUORURO DE HIDROGENO COMO PARA FORMAR UN MEDIO DE REACCION DE DOS FASES. POR LO TANTO, SORPRENDENTEMENTE, EL COMPUESTO AROMATICO ACILATADO O ALQUILATADO DEL COMPUESTO ES SOLUBLE EN FLUORURO DE HIDROGENO. LA INVENCION SE REFIERE PARTICULARMENTE AL USO DE UN PROCESO MULTIETAPA CONTINUO PARA REALIZAR LA REACCION DE ALCILATACION O ALQUILATACION. EN EL PROCESO MULTIETAPA, LA FASE CONTINUA PUEDE SER TANTO LA FASE RICA EN FLUORURO DE HIDROGENO COMO LA FASE RICA EN COMPUESTO AROMATICO. EL MOVIMIENTO DE LA FASE CONTINUA CON RELACION A LA FASE DISPERSA NO CONTINUA PUEDE SER A CONTRACORRIENTE O CONCURRENTEMENTE. EL PROCESO MULTIETAPA PUEDE SER CONTROLADO DE FORMA TAL QUE LA ALIMENTACION DEL COMPUESTO AROMATICO A LA REACCION SEA ENTERAMENTE CONSUMIDA O TAL QUE EL COMPUESTO AROMATICO QUE NO HAYA REACCIONADO SE PUEDA RECICLAR.
