Abstract
METODO PARA ACILAR DERIVADOS DE NAFTALENO, DE FORMULA GENERAL (I). CONSISTE EN PONER EN CONTACTO UNA MEZCLA DE REACCION DEL DERIVADO O COMPUESTO DE NAFTALENO Y EL AGENTE ACILANTE, CON FLUORURO DE HIDROGENO ANHIDRO A UNA TEMPERATURA COMPRENDIDA ENTRE 40 Y 100 GRADOS Y DURANTE EL TIEMPO SUFICIENTE PARA DAR LUGAR A LA ACILACION SUSTANCIALMENTE COMPLETA DEL COMPUESTO DE NAFTALENO AL COMPUESTO DE 6-ACILNAFTALENO. EL PRODUCTO OBTENIDO SE AISLA DE LA MEZCLA DE REACCION. COMO AGENTES ACILANTES SE UTILIZAN ACIDOS ALQUILO INFERIOR-CARBOXILICOS, ANHIDRIDOS DE ACIDOS ALQUILO INFERIOR-CARBOXILICOS, Y CETONA. DE APLICACION COMO PRODUCTOS FARMACEUTICOS.
