Abstract
PROCEDIMIENTO DE OBTENCION DE AMIDA DE ACIDO 3-CIANO-PROPIONICO. CONSISTE EN HACER REACCIONAR POR ADICON ACIDO CIANHIDRICO CON AMIDA DE ACIDO ACRILICO EN PRESENCIA DE UN DISOLVENTE ORGANICO APROTICO Y DE UN CIANURO DE METAL ALCALINO A UNA TEMPERATURA ENTRE 20 Y 150 GC. COMO DISOLVENTE ORGANICO APROTICO SE EMPLEA DIMETILFORMAMIDA O DIMETILSULFOXIDO. COMO CIANURO DE UN METAL ALCALINO SE EMPLEA CIAMURO SODICO Y POTASICO. EL ACIDO CIANHIDRICO SE EMPLEA EN CANTIDAD ESTEQUIOMETRICA CON RESPECTO A LA AMIDA DE ACIDO ACRILICO, PUDIENDO EMPLEARSE TAMBIEN EN ESCASO EXCESO. LA PRESION NO TIENE INFLUENCIA SOBRE LA VELOCIDAD DE REACCION.
