Acrylonitrile is a monomer used in the syntheses of many polymers in Organic Chemistry. Currently commercialy available acrylonitrile originates from petrosourced propene or propane. Its synthesis is usually done with the “Sohio” process. This reaction is undergone in gas phase fluidized bed reactor under high temperature (350°C – 400°C) without water and with a bismuth and molybdene-based catalyst. However, this process uses propen whose price keeps on increasing. There is therefore a demand for a process independent from propene while still offering high yields.
In the present work, the inventors aimed at setting up a process to synthesize acrylonitrile from allyl alcohol knowing that said raw material can also be biosourced.
They have therefore developped a antimony- and iron-based catalyst for production of nitrile (acrylonitrile) to do such target reaction.
The present invention is definitely innovative as:
This first targetted application is the synthesis of acrylonitrile. This monomer can then be used for the syntheses of acrylic fibers, Acrylonitrile butadiene styrene resin (ABS), Styrene acrylonitrile resin (SAN) and nitrile rubber (NBR).
