The Nitrilation to Acrylonitrile Process provides a sustainable route to produce acrylonitrile and carbon fibers via nitrilation chemistry, offering a cost-effective alternative to the conventional petrochemical production, while also achieving even greater yields of acrylonitrile than the state-of-the-art ammoxidation
The by-products in the process of propylene ammoxidation
are mainly hydrogen cyanide, acetonitrile, acrolein, carbon dioxide and carbon monoxide.
The 12 papers describe metal organic frameworks, membrane facilitated defluoridation of water, catalytic conversion of carbon dioxide into fuels and chemicals, ammoxidation
of hetero-aromatic compounds to corresponding nitriles, oxidative dehydrogenation of ethane to ethylene, and base catalyzed transesterification for biodiesel.

They begin by describing the fundamentals of integrated process design, then get into specifics by describing case studies relating to process synthesis using the hierarchical approach, synthesis of separator systems, reactor/separation/recycling systems, phenol hydrogenation to cyclohexone, alkylation of benzene by propylene to cumene, vinyl chloride monomer processing, fatty-ester synthesis by catalytic distillation, isobutane alkylation, vinyl acetate monomer processing, acrylonitrile by propene ammoxidation
, biochemical processes for nitrogen oxide removal, polyvinylchloride manufacturing by suspension polymerization, biodiesel and bioethanol manufacturing.
MXDA has been manufactured by ammoxidation
of pure meta-xylene into isophthalonitrile, followed by hydrogenation of the nitrile in the presence of ammonia using a nickel catalyst or other metallic catalyst under high temperature and pressures.
5,883,281 that covers a process for increasing the yield of acrylonitrile by adding oxygen to reduce inerts in an ammoxidation
Three different methods for the production of these adsorbents were investigated: activation with C[O.sub.2], heat treatment with ammonia gas (amination and ammoxidation
), and heat treatment with polyethylenimine (PEI).
