Abstract

SE PRESENTA UN PROCESO PARA LA ALFA-CLORACION DE FENILACETONITRILOS, POR EJEMPLO CIANURO DE BENZIL, EN EL CUAL EL FENILACETONITRILO SE PONE EN CONTACTO CON UN AGENTE CLORADOR ADECUADO, CLORURO DE SULFURIL O GAS DE CLORO, MIENTRAS UNA CANTIDAD DE UN ACIDO FUERTE, PREFERIBLEMENTE HCL, ESTA TAMBIEN PRESENTE EN LA MEZCLA DE REACCION. EL TIEMPO DE INDUCCION Y LA VELOCIDAD DE REACCION DEPENDEN DE, ENTRE OTROS FACTORES, LA CONCENTRACION DEL ACIDO. PREFERIBLEMENTE, LA REACCION SE LLEVA A CABO BAJO PRESION. LA REACCION ES FACILMENTE CONTROLABLE.
