Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE PREPARACION DE FLUOROALCOHOLATOS DE SODIO. ESTE PROCEDIMIENTO CONSISTE EN EFECTUAR LA SODACCION DE LOS ALCOHOLES FLUORADOS POR MEDIO DE METILATO DE SODIO, Y EN ATRAPAR EL METANOL POR MEDIO DE UN TAMIZ MOLECULAR. LOS FLUOROALCOHOLATOS DE SODIO SON DIRECTAMENTE UTILIZABLES PARA REACCIONES DE SUSTITUCION DE POLIDICLOROFOSFACENOS.
