Presentation: Continuous Processing

Features:

• Corrosion-resistant materials (PVDF, PTFE, glass, Viton, ceramics)
• Flexible tubing (UNF ¼” 28 G fittings + PTFE tubes)
• 18 reactor glass pipes connected in series for a total length of 16 m
• Maximum residence time: 2.7 min @ 0.1 m/s flow
• Temperature control: ± 2 °C
• Up to 4 pumps with 1 % accuracy @ 10-150 ml/min flow
• 1 p/T probe for main-flow control, 1 pH/T probe, 2 additional T probes
• Magnet valve for precision sampling at the outlet

Application example (3-step continuous acetylation):

• Total flow rate (substrate + 50 % NaOH + acetic anhydride): 124 ml/min
• Residence time for 100 % turnover: 24 s
• Continuous work-up by parallel addition of acid (ex reactor)
• Capacity: 39.3 g/min of crude product (2.36 kg/h)
• Highest ?Tad : 73 °C @ 33 °C bath temperature, solvent: water
• Total heat generation: 1.1 kW
