Abstract
PROCEDIMIENTO PARA LA PREPARACION DE MALONONITRILO. CONSISTE EN LA REACCION DE DIAZOACETONITRILO CON CIANURO DE HIDROGENO EN PRESENCIA DE UN COMPUESTO DE COBRE Y EN UN DISOLVENTE; L TEMPERATURA DE REACCION OSCILA ENTRE 0 Y 50<025>C. EL COMPUESTO DE COBRE SE SELECCIONA ENTRE SULFATO DE COBRE MONO O BIVALENTE, CARBONATO DE COBRE, ACETATO, CIANURO, PERDORATO O CLORURO DE COBRE; DICHO COMPUESTO DE COBRE ES AÑADIDO EN UNA PROPORCION COMPRENDIDA ENTRE 0,001 Y 2 GRAMO-ATOMOS EN TERMINOS DE COBRE METALICO POR MOL DE DIAZOACETONILO. EL DISOLVENTE SE ELIGE ENTRE ETIL ETER, CLORURO DE METILENO, CLOROFORMO, TETRACLORURO DE CARBONO, N-HEXANO Y AGUA. EL PH OSCILA ENTRE 3 Y 12.
