Reaktionsschritte

A mixture of approximately 70 weight percent cis-2-pentenenitrile, 14 weight percent 2-methyl-2-butenenitrile, 4 weight percent 2-methyl-3-butenenitrile, with cyclohexane, benzene, and valeronitrile making up the balance, was reacted with 29 weight percent aqueous ammonia (at 15 percent molar excess relative to cis-2-pentenenitrile) in a stirred batch reactor at about 90° to 100° C., at an autogeneous pressure of about 60 to 118 psig, for approximately ten hours Vacuum distillation of the crude reaction mixture to remove low boiling impurities and water resulted in 91% selectivity to 3-aminopentanenitrile at 97% conversion of the starting cis-2-pentenenitrile
