Flow synthesis of 1-ethyl-3-methylimidazolium ethyl sulfate in a PTFE micro-capillary: an experimental and numerical study
In this work, we have reported continuous flow synthesis of 1-ethyl-3-methylimidazolium ethyl sulfate ionic liquid in a PTFE micro-capillary. A Y-shaped microfluidic junction is used to mix the incoming reactants. Effects of independent parameters like velocity, reaction temperature, and micro-capillary diameter on product yield, rate of production, and space–time yield are reported. Yield is seen to increase monotonically as reaction temperature is increased, while it reduces with an increase in diameter of the micro-capillary. A maxima in yield is observed as flow velocity is increased. A space–time yield of 1258.4 g/min.L is obtained at a reaction temperature of 80 0C using a 300 µm micro-capillary. A two-dimensional computational fluid dynamics (CFD) model of the reacting system has been developed to confirm and explain the observed experimental trends. The simulations were able to qualitatively predict the experimental trends. The simulations also investigated the effect of shapes of different obstacles placed in the flow path.
期刊介绍:
Microfluidics and Nanofluidics is an international peer-reviewed journal that aims to publish papers in all aspects of microfluidics, nanofluidics and lab-on-a-chip science and technology. The objectives of the journal are to (1) provide an overview of the current state of the research and development in microfluidics, nanofluidics and lab-on-a-chip devices, (2) improve the fundamental understanding of microfluidic and nanofluidic phenomena, and (3) discuss applications of microfluidics, nanofluidics and lab-on-a-chip devices. Topics covered in this journal include:
1.000 Fundamental principles of micro- and nanoscale phenomena like,
flow, mass transport and reactions
3.000 Theoretical models and numerical simulation with experimental and/or analytical proof
4.000 Novel measurement & characterization technologies
5.000 Devices (actuators and sensors)
6.000 New unit-operations for dedicated microfluidic platforms
7.000 Lab-on-a-Chip applications
8.000 Microfabrication technologies and materials
Please note, Microfluidics and Nanofluidics does not publish manuscripts studying pure microscale heat transfer since there are many journals that cover this field of research (Journal of Heat Transfer, Journal of Heat and Mass Transfer, Journal of Heat and Fluid Flow, etc.).
