Production methods
Propanol with ammonia, propionitrile or acrylonitrile hydrogenation or reductive amination can be prepared propylamine propionaldehyde. The reaction propylamine, dipropylamine, a mixture of tri-n-propylamine. Obtained by fractionation of pure components. Propanol with ammonia method is the method used in the industry. (1) n-propanol to n-propanol as a raw material, in the role of catalyst nickel – copper – alumina (Ni-Cu-Al2O3) is 190 ± 10 ° C temperature of the reaction, the dehydrogenation of propionaldehyde with ammonia plus was imine into dehydration, propanol and the proportion of ammonia control, and then hydrogenation of propylamine, but at the same time there are two propylamine, tripropylamine generated (see “tripropylamine). 2-nitropropane France nitro-propyl low pressure catalytic hydrogenation of propylamine.
Use
Propylamine as organic synthesis of raw materials for medicines, paints, pesticides, rubber, fiber, textiles and resin finishing agent, petroleum additives and preservatives, also used as a reagent. Pesticides, can produce herbicide chloroacetyl fluoride spirit and cyclopropane fluorine spirit. Propylamine uses as dipropylamine.
