3. Continuous flow synthesis advantages

4. Most favourable conditions

5. Diagram for microchannel reactor

6. Microchannel reactor animations

7. Reaction

8. Green method reaction

9. conclusion The experiments at different temperatures showed a positive relationship between the selectivity of 5NSA and temperatures. Also, a higher amount of the nitrating agent was seen to reduce the reaction time and achieve higher selectivity for the desired product. A continuous flow experiment at 50 °C with 7 min residence time for 2 h yielded consistent outlet composition.
