Acrylonitrile is prepared by a process which comprises the ammoxidation of propylene with ammonia and molecular oxygen or a gas containing molecular oxygen at from 300° to 600° C. in the presence of a metal oxide catalyst which contains tellurium and one or more of the metals iron, molybdenum...
Multifunctionality is the hallmark of most modern commercial heterogeneous catalyst systems in use today, including those used for the selective ammoxidation of propylene to acrylonitrile. It is the quintessential principle underlying commercial catalyst design efforts since petrochemical process development is ...
Ammoxidation refers to a reaction in which a methyl group with allyl hydrogens is converted to a nitrile group using ammonia and oxygen in the presence of a mixed oxide–based catalyst. A successful application of this reaction produces acrylonitrile from propylene: 2CH3CHCH2 + 2NH3 + 3O2→ ...
names such as Orlon (DuPont) and Acrilan (Monsanto). Acrylonitrile is also a reactant in the synthesis of dyes, pharmaceuticals, synthetic rubber, and resins. Acrylonitrile production occurs primarily through ammoxidation of propylene: CH3- CH = CH2 + NH3 + 1.5O2→CH2 = CH - CN + 3 H2O....
