Abstract
A method for the production of an amine from a nitrile utilizing hydrogenation by; feeding hydrogen and nitrile into a reactor including catalyst, water and inorganic base to form a reaction medium; mixing the reaction medium to provide a uniform bulk concentration of the nitrile in at least one direction across the reactor to minimize the reactor volume where local bulk nitrile concentration exceeds that stoichiometrically required to completely deplete the local bulk hydrogen concentration; and hydrogenating the nitrile to form the amine.
Claims21
A method for the production of an amine from a nitrile by hydrogenation comprising;
- feeding hydrogen and nitrile into a reactor comprising catalyst, water and inorganic base to form a reaction medium;
- mixing said reaction medium to provide a uniform local bulk concentration of said nitrile in at least one direction across said reactor;
- and
- hydrogenating said nitrile to form said amine.
A method for the production of an amine from a nitrile by hydrogenation comprising;
- feeding hydrogen and nitrile into a reactor comprising catalyst, water and inorganic base to form a reaction medium;
- mixing said reaction medium to minimize regions having a local bulk concentration of said nitrile greater than the local bulk concentration of said hydrogen throughout the volume of said reactor;
- and
- hydrogenating said nitrile to form said amine.
