Abstract
PROCEDIMIENTO DE OBTENCION DE PRODUCTOS DE REACCION DEL CIANURO DE HIDROGENO. CONSISTE EN LA OBTENCION DE CIANURO DE HIDROGENO POR PIROLISIS DE COMPUESTOS, TALES COMO FORMAMIDA, DERIVADOS DE N-ACILO DEL L-AMINO-L-CIANO-ETANO O SUS PRODUCTOS DE SUSTITUCION, A UNA TEMPERATURA ENTRE 250 Y 650JC, BAJO UNA PRESION DE 5 A 200MBAR. LOS PRODUCTOS DE PIROLISIS SE ENFRIAN A TEMPERATURA DE 200 A C10JC DANDO LUGAR A LA CONDENSACION DE TODOS AQUELLOS PRODUCTOS QUE POSEEN UN PUNTO DE EBULLICION SUPERIOR AL DEL CIANURO DE HIDROGENO, QUE SIN CONDENSAR SE SOMETE A ABSORCION QUIMICA CON BASES(HIDROXIDO DE SODIO O POTASIO) O CON COMPUESTOS DE CARBONILO(ALDEHIDOS DE 1 A 4 ATOMOS DE C, CETONAS) A UNA PRESION DE 5 A 140MBAR. Y BAJO TEMPERATURA COMPRENDIDA ENTRE C20 Y B30JC. CUANDO LA ABSORCION QUIMICA SE REALIZA CON COMPUESTOS DE CARBONILO SE AÑADEN AMINAS DEL TIPO R1-NH-R2 DONDE R1 Y R2 SON RADICALES ALQUILICOS DE 1 A 8 ATOMOS DE C; EN UNA PROPORCION EN PESO 1:1:1 DE CIANURO DE HIDROGENO, AMINA, COMPUESTO CARBONILO.
