a cost effective production of hydrogen peroxide via improved mass transfer of oxygen for electro fenton process using the vertical Flow Reactor
Separation and Purification Technology, 2020Co-Authors: Yang Chen, Yuwei Pan, Yang YangAbstract:Abstract This study has investigated a novel jet-type Reactor (vertical Flow Reactor) in order to improve the oxygen utilization for enhanced production of hydrogen peroxide (H2O2). In vertical Flow electro-Fenton (EF) system, the effects of current density, water Flow rate, Fe2+ concentration and initial pH were investigated for the removal of tetracycline hydrochloride. The efficient removal of tetracycline hydrochloride could reach 100% within 60 min under the current density of 24 mA cm−2, water Flow rate of 10 L h−1 and pH of 3. The vertical Flow Reactor was relatively stable and reusable for the removal of pollutants. The removal rates of tetracycline hydrochloride and total organic carbon (TOC) were maintained at about 95% and 80%, respectively in a 5-time continuous runs. Moreover, the vertical Flow Reactor could efficiently remove a wide type of organic pollutants, and the TOC removals of acid magenta, rhodamine B, alizarin yellow R, orange Ⅳ and diclofenacdium were 75.96, 77.90, 61.27, 72.11 and 82.89%, respectively after 3 h of reaction time. Cathodic adsorption, anodization, and H2O2 oxidation played minor roles in the removal of tetracycline hydrochloride, while the OH radicals are the most pivotal oxidizing substance in the system. As compared with the traditional aeration, the vertical Flow Reactor has a high-speed jet Flow state, which makes the liquid-gas mixture homogeneous, and renders it high oxygen absorption rate, cost effectiveness and high power efficiency for the degradation of pollutants.

real time monitoring of solid phase peptide synthesis using a variable bed Flow Reactor
Chemical Communications, 2019Co-Authors: Eric T Sletten, Peter H. Seeberger, Manuel Nuno, Duncan GuthrieAbstract:On-resin aggregation and incomplete amide bond formation are major challenges for solid-phase peptide synthesis that are difficult to be monitored in real-time. Incorporation of a pressure-based variable bed Flow Reactor into an automated solid-phase peptide synthesizer permitted real-time monitoring of resin swelling to determine amino acid coupling efficiency and on-resin aggregation.

facile azide formation via diazotransfer reaction in a copper tube Flow Reactor
ChemInform, 2015Co-Authors: Koen Nuyts, Matthias Ceulemans, Tatjana N Paracvogt, Geert Bultynck, Wim M De BorggraeveAbstract:The conversion of primary amines into organic azides using AZS as the azide source is catalyzed by copper from the copper tube Flow Reactor.

facile azide formation via diazotransfer reaction in a copper tube Flow Reactor
Tetrahedron Letters, 2015Co-Authors: Koen Nuyts, Matthias Ceulemans, Tatjana N Paracvogt, Geert Bultynck, Wim M De BorggraeveAbstract:A copper tube Flow Reactor is used in the conversion of primary amines into organic azides using imidazole-1-sulfonyl azide hydrogen sulfate. The catalyst is generated in situ from the metallic copper. The reaction can be quenched in acidic environment or via a cycloaddition of the azides formed with an alkyne. The possibility to perform this azide-alkyne cycloaddition using the copper released from the Reactor is demonstrated with the synthesis of both a 1,2,3-triazole derivative of benzylamine and of a more complex BODIPY–DOTA adduct.
