Abstract
SE PRESENTA UN PROCESO PARA LA PRODUCCION DE 6-HIDROXI-2-NAFTONAS, P.E. 6-HIDROXI-2-ACETONAFTONA, POR CONTACTO DE UN ESTER DE 2-NAFTIL CARBOXILADO CON AL MENOS 20 MOLES DE FLUORURO DE HIDROGENO POR MOL DE 2-NAFTIL ESTER, A TEMPERATURAS DE REACCION, P.E., 0 A 100 GRADSOSS C PARA UN PERIODO DE REACCION, P.E., 30 MINUTOS A 8 HORAS SUFICIENTE PARA PRODUCIR LA CANTIDAD DESEADA DE 6-HIDROXI-2-NAFTONA. EL PROCEDIMIENTO PUEDE UTILIZAR UN ACIDO O ANHIDRIDO CARBOXILICO, P.E., ACIDO O ANHIDRIDO ACETICO COMO ADITIVO CON EL FIN DE AUMENTAR ADEMAS LA REGIOSELECTIVIDAD DEL PRODUCTO FINAL 6-HIDROXI-2-NAFTONA. EL METODO ES CAPAZ DE OBTENER UNA CONVERSION DE 2-NAFTIL ESTER DE AL MENOS EL 90% Y UNA REGIOSELECTIVIDAD A 6-HIDROXI-2-NAFTONA DE AL MENOS 90 MOL %.
