Abstract

Development of 3D printed stainless steel reactors for the oxidation of Grignard reagents in continuous flow.

Highlights

  • Rapid developments in the field of 3D printing show a successful production of milli- and microreactors especially designed for the needs of the process.[9,10,11,12,13,14,15,16,17] The lack of robustAssoc

  • Aerobic oxidation of Grignard reagents to the corresponding phenols was selected as a model reaction for the evaluation of both, oxygen sensor performance and mixing efficiency of the 3D printed reactors

  • A combination of Selective laser melting (SLM) 3D printing of stainless steel and the implementation of novel oxygen sensors for the inline measurement was shown to be a promising combination for investigating the oxidation of Grignard reagents in flow. 3D printing is a favourable tool for the creation of adaptable reactors and implementation of sensors

Summary

Introduction

Rapid developments in the field of 3D printing show a successful production of milli- and microreactors especially designed for the needs of the process.[9,10,11,12,13,14,15,16,17] The lack of robustAssoc. The reactor design for the resulting one phase system was guided by monitoring the oxygen consumption rate during oxidation of the Grignard reagent through implemented novel optical inline oxygen sensors. With this cascade it was possible to estimate the dependency of the oxidation reaction on the degree of mixing by monitoring the oxygen consumption rate with the integrated novel oxygen sensors in the CSTR vessels.
