Abstract

Important features for flow chemistry systems are a narrow residence time distribution, appropriate sample volume and small pressure drop. These criteria were evaluated by studying hydrodynamic characteristics of tubular microflow systems using Computational Fluid Dynamics and experimental tracing breakthrough curves in a novel multi-bore Microcapillary Film Reactor (MFR). The inner diameter and diffusion coefficient of molecular species had a large influence on approaching ideal plug flow. Compared to a single large bore capillary (2400 μm i.d.), the MFR (363±32.2 μm) provides opportunity for improving product yields via excellent radial mixing whilst exhibiting all desired qualities for a high-performance flow system.
