Enantioselective liquid-liquid extraction in microreactors
Susanti
1. The explanation given by Woitalka et al. to explain the flow behaviour in microchannels for 1-butanol and water at equal inlet flow rates is not correct. (Woitalka, A.; Kuhn, S.; Jensen, K. F. Chem. Eng. Sci. 2014, 116, 1)
2. It is not very likely that Taylor flow is obtained in microchan-nels when using residence times above 60 s when stratified flow is observed at residence times in the range of 20 to 30 s. (Woitalka A., Kuhn S., Jensen K. F. Chem. Eng. Sci. 2014, 116, 1) 3. The use of the term solubility of a racemate in an organic phase
instead of partitioning of the racemate in a water/organic sol-vent system is not recommended. (Lu R., et al. Chirality. 2017, 29, 708)
4. The change in enantiomeric preference as a function of the pH for the separation of m-PGA in water with a chiral crown ether in toluene is puzzling and requires further attention. (Schuur B., et al. Chirality. 2015, 27, 123)
5. The observation that variations in the total flow rate and micro reactor length at constant residence times have no impact on (Kova)Phys (this thesis, Chapter 2) is in agreement with the
find-ings from Tsaoulidis and Angeli. (Chem. Eng. J. 2015, 262, 785). 6. Continuous enantioselective liquid-liquid extraction (ELLE) in
microreactors has good potential for scale up (this thesis). 7. Having a single name seems simple, yet is complicated. 8. The concept of chiral complexation is also valid when children
have to put on their shoes.
9. You may not always get what you want on time, but you do get what you want at the right time.
