Abstract

"PROCESSO PARA A FABRICAçãO DE 6-AMINOCAPROATO DE ALQUILA" A presente invenção refere-se a um processo para a fabricação de 6-aminocaproato de alquila, pela hidroformilação de 3-pentenonitrila para produzir 3-, 4- e 5-formilvaleronitrila (mistura FVN), conversão da mistura de FVN em 3-, 4- e 5-cianovalerato de alquila ou por esterificação oxidativa da mistura de FVN ou por oxidação da mistura de FVN seguida por esterificação; isolamento do 5-cianovalerato de alquila; e hidrogenar o 5-cianovalerato de alquila para produzir 6-aminocaproato de alquila. O 6-aminocaproato de alquila resultante pode ser ciclizado para produzir caprolactama.
