Abstract
PROCESO PARA LA ELABORACION DE P - HIDROXIBENZALDEHIDOS DE LA FORMULA GENERAL I EN DONDE EL ANILLO AROMATICO PUEDE PORTAR DE 2 HASTA 4 SUSTITUYENTES INERTES, MEDIANTE OXIDACION ELECTROQUIMICA DE UN FENOL DE LA FORMULA GENERAL II EN PRESENCIA DE UN ALCANOL R{SUP,1}OH, DONDE EL RESTO R{SUP,1} ES UN RESTO C{SUB,1} - C{SUB,6} - ALQUILO, DONDE LA REACCION SE REALIZA EN PRESENCIA AL MENOS DE UNA BASE ORGANICA O INORGANICA AL MENOS EN CANTIDAD ESTEQUIOMETRICA, DE FORMA QUE UN FENOL DE LA FORMULA II PUEDE TRANSFORMARSE EN EL CORRESPONDIENTE ION FENOLATO, QUE SE FAMILIARIZA DE FORMA HIDROLITICA CON LA MEZCLA DE REACCION Y AISLA EL ALDEHIDO DE LA FORMULA I.PROCESS FOR THE ELABORATION OF P - HYDROXYBENZALDEHYDE FROM THE GENERAL FORMULA I WHERE THE AROMATIC RING CAN CARRY FROM 2 TO 4 INERT REPLACEMENTS, THROUGH ELECTROCHEMICAL OXIDATION OF A PHENOL OF THE II GENERAL SUPPLY {A , WHERE THE REST R {SUP, 1} IS A REST C {SUB, 1} - C {SUB, 6} - RENT, WHERE THE REACTION IS PERFORMED IN PRESENCE AT LEAST OF AN ORGANIC OR INORGANIC BASE AT LEAST IN ESTEKIOMETRIC AMOUNT, SO THAT A PHENOL OF FORMULA II CAN BE TRANSFORMED INTO THE CORRESPONDING ION PHENOLATE, WHICH IS HYDROLYTICALLY FAMILIARIZED WITH THE REACTION MIXTURE AND ISOLATES THE ALDEHYDE OF FORMULA I.
