Abstract

PROCEDIMIENTO DE OBTENCION DE N-VINILFORMAMIDA. CONSISTE EN SOMETER A PIROLISIS FORMILALANINONITRILO, EN PRESENCIA DE UN CATALIZADOR CONSTITUIDO POR CARBONATO U OXIDO ALCALINO O ALCALINOTERREO SOLIDO, SOBRE OXIDO DE A-ALUMINIO COMO SOPORTE; A TEMPERATURA DE 250 A 650JC, BAJO UNA PRESION DE 10 A 15MBAR. Y EN PRESENCIA DE 0,1 A 2 MOLES DE FORMAMIDA POR MOL DE FORMILALANINONITRILO, COMO DILUYENTE Y PROTECTOR DEL CATALIZADOR. LOS PRODUCTOS DE PIROLISIS SON ENFRIADOS A UNA TEMPERATURA DE 200JC A C10JC Y A PRESION DE 10 A 150MBAR. OBTENIENDOSE UNA SEPARACION FRACCIONADA DE N-VINILFORMAMIDA CONDENSADO Y CIANURO DE HIDROGENO GASEOS. SE AISLA EL N-VINILFORMAMIDA PURIFICANDOLO Y EL CIANURO DE HIDROGENO SE SOMETE A ABSORCION QUIMICA CON ACETALDEHIDO, A TEMPERATURA DE C20 A 30JC. SE OBTIENE NITRILO LACTICO, QUE POR REACCION CON FORMAMIDA DA LUGAR A FORMILALANINONITRILO, PRODUCTO QUE SERA PIROLIZADO DE FORMA CONTINUA.
