Abstract

PROCEDIMIENTO PARA LA PREPARACION DE 6-METIL-3,4-DIHIDRO-1,2,3-OXATIAZIL-4-ON-2,2-DIOXIDO. EL ACIDO ACETOACETAMIDO-N-SULFONICO Y SUS SALES SE CICLIZAN CON UNA CANTIDAD POR LO MENOS APROXIMADAMENTE EQUIMOLAR DE SO3 EN BREVES TIEMPOS, PREFERIBLEMENTE EN DISPOSITIVOS ESPECIALES, PARA FORMAR 6-METIL-3,4-DIHIDRO-1,2,3-OXATIAZIN-4-ON-2,2-DIOXIDO. EN EL CASO DE EMPLEARSEUNA CANTIDAD DE SO3 MAYOR QUE LA EQUIMOLAR, RESULTA EL COMPUESTO MENCIONADO EL ULTIMO TERMINO COMO ADUCTO CON SO3, QUE TODAVIA DEBE SER HIDROLIZADO; TAMBIEN LA HIDROLISIS DISCURRE EN BREVES TIEMPOS Y DE MODO ESPECIALMENTE VENTAJOSO EN DISPOSITIVOS DEL MISMO TIPO QUE PARA LA CICLIZACION. LAS SALES NO TOXICAS -ESPECIALMENTE LA SAL POTASICA- DEL 6-ETIL-3,4-DIHIDRO-1,2,3-OXATIAZIN-4-ON-2,2-DIOXIDO SON VALIOSOS AGENTES EDULCORANTES SINTETICOS.
