Abstract

SE PREPARA 6-METIL-3,4-DIHIDRO-1,2,3-OXATIAZIN-4-ON-2,2-DIOXIDO MEDIANTE CIERRE DE ANILLO DE ACETOACETAMIDO-N-ACIDO SULFONICO O DE SUS SALES CON UNA CANTIDAD POR LO MENOS CASI EQUIMOLAR DE SO3 EN PRESENCIA DE UN DISOLVENTE ORGANICO INERTE. PARA EL TRATAMIENTO, EN EL CASO DE EMPLEARSE UNA CANTIDAD EQUIMOLAR DE SO3, DESPUES DE HABERSE TERMINADO LA REACCION DE CIERRE DE ANILLO SE AÑADE ACIDO SULFURICO ACUOSO; EN EL CASO DE EMPLEARSE UNA CANTIDAD DE SO3 MAYOR QUE LA EQUIMOLAR SE HIDROLIZA POR ADICION DE AGUA O DE HIELO EL 6-METIL-3,4-DIHIDRO-1,2,3-OXATIAZIN-4-ON-2,2-DIOXIDO RESULTANTE COMO ADUCTO CON SO3, RESULTANDO ACIDO SULFURICO A PARTIR DEL SO3 FIJADO EN EL ADUCTO CON SO3. A PARTIR DE LA RESULTANTE MEZCLA DE VARIAS FASES SE SEPARA ENTONCES POR DESTILACION EL DISOLVENTE ORGANICO INERTE Y A PARTIR DE LA FASE ACUOSA EN ACIDO SULFURICO, REMANENTE, SE OBTIENE EN FORMA PURA POR CRISTALIZACION EL 6-METIL-3,4-DIHIDRO-1,2,3-OXATIAZIN-4-ON-2,2-DIOXIDO. ADEMAS DE ELLO, DE MANERA ENTERAMENTE GENERAL, SE PURIFICA A PARTIR DE ACIDO SULFURICO ACUOSO, POR RECRISTALIZACION, 6-METIL-3,4-DIHIDRO-1,2,3-OXATIAZIN-4-ON-2,2-DIOXIDO PURO. LAS SALES NO TOXICAS DEL 6-METIL-3,4-DIHIDRO-1,2,3-OXATIAZIWN-4-ON-2,2-DIOXIDO ESPECIALMENTE LA SAL POTASICA SON SUSTANCIAS EDULCORANTES SINTETICAS VALIOSAS.
