Toxic Pollutant to Pharma Feedstock with Emulsion Hydrogenation (IMAGE)
Caption
UJ researchers take a novel step to change hydrogenation into a safe, low energy process. They use a very stable three phase emulsion to transform a toxic waste product into valuable feedstock. The process does not need flammable, compressed hydrogen gas. It turns nitrobenzene efficiently into aniline at room temperature.
By using emulsion chemistry, there is one system where catalyst, emulsifier, aqueous and organic phase all mix up into an extremely stable gel.
Chemists from the University of Johannesburg have demonstrated this, in research published in Colloids and Surfaces at https://www.sciencedirect.com/science/article/abs/pii/S0927775721003824
