Profitability from Industrial Green Chemistry and Engineering

Reduction Chemistry made profit-centric by Newreka’s Platform Technology #2


You may remember reading about Newreka’s Platform Technology #1. It is now time to discuss Platform Technology #2 for Nitro to Amine reduction.

Chemistry : Aromatic Nitro to Amine reduction

Applicable : When the nitro is soluble in water and amine is soluble in alkaline solution

‘Greener’ alternative to conventional approach :

  • The nitro is reduced in water in the presence of Newreka’s proprietary catalyst “G-Cat”
  • The pH is made alkaline, i.e. neutralization takes place. The spent G-Cat is filtered out and the product is isolated
    and then filtered out
  • The acidic mother liquor then undergoes “R-Cat” processing and purification to remove organic and inorganic
    impurities. It is then recycled into the reaction vessel where it originally came from.

Products that can benefit from this technology :

  Molecule   Nitro   CAS no   Amine   CAS no
  MPDSA   1,3-Dinitro-4-sulphonic
  89-02-1   1,3-diamino-4-
