Greensyn is highly specialised in Hydrogenation, Cyanidation, Azide Reaction, Halogenation (Chlorination, Bromination).The safe handling of corrosive and hazardous material belongs therefore to our core competencies. We also strong in the extracting ingredients from plant.
Azide Reaction
Based on solid experience of using azide sodium, we are strong in the azide reaction.
Cyanidation
Hydrogenation
Hydrogelation is carried out using sponge-Nickel and palladium charcoal catalysts, especially high pressure , temperature and selectivity required.
Hydrogenation catalysed with Ra-Ni
Pressure: 7.0-12.0 Mpa
Temp.: 200-250°C
Selective Hydrogenation catalysed with Ra-Ni
Halogenation (Chlorination, Bromination)
Chlorination with Thionyl chloride
Chlorination with chlorine
Bromination with Bromine
Amination
Amination with amino
Amination by reduction of nitro/nitroso compd.
Synthesis of optically active compd.
Mainly produce it by optical resolving
Extracting
Greensyn has 3 years experience in the manufacture of phyto-chemicals for Pharmaceuticals, food and cosmetic use. Especially in producing anti-malaria API like Artemisinin. |
