Reactor Concept for Contactless Kinetic Measurement in Oscillating Droplets via Raman Spectroscopy.

A millistructured reactor and spectroscopic setup for contactless kinetic measurements in oscillating droplets is presented in this work. The polymerization of acrylic acid serves as a model reaction. Design and construction of the reactor focus on the optical access for Raman measurement, the nearly isothermal behavior, and the preservation of droplets during long‐term reactions with a high increase of viscosity. Another key aspect is the possibility of full automation at a later stage. [ABSTRACT FROM AUTHOR]
