A continuous flow generator of organic hypochlorites for the neutralization of chemical warfare agent simulants

Abstract

Herein is reported the development of a continuous flow generator that produces highly reactive organic hypochlorites for the chemical neutralization of sulfur-based chemical warfare agent (CWA) simulants. The generator relies...

Will the next generation of chemical plants be in miniaturized flow reactors?

“…This has been successfully performed with commercial oxidizing reagents 66,67 or by generating more reactive/unstable oxidants upstream in the flow system. 68,69 The fine control of the conditions in the miniaturized reactor avoids the formation of undesired and harmful overoxidized products (Scheme 5).…”

Soft detoxification of chemical warfare agent simulants and pesticides under pressure

“…Recently, continuous flow reactors have attracted attention as an alternative to classical batch chemistry to ensure rapid and selective neutralization of such harmful chemicals with oxidizing agents. [16][17][18][19] Moreover, successful neutralisation by direct introduction of an aqueous solution of sodium hydroxide in the flow system has also been reported, 20 whereas a 3D-printed chemical generator of lithium ethanolate has been later reported as a reliable method. 21 Importantly, all these methods are not general and each focuses on a specific class of compounds: yperite, 16,17,19 V-series OPNAs, 21 sulfur-containing CWAs, 18 or Paraoxon.…”

Continuous Flow Photooxidative Degradation of Azo Dyes with Biomass‐Derived Carbon Dots

“…[49][50][51][52] The photodegradation of azo dyes in continuous flow conditions is still an underexplored topic even if inherent advantages of the microreactor system, such as the high surface-to-volume ratio, short ChemPhotoChem diffusion distances, and rapid mass transfer, can improve the photocatalytic performance degrading organic contaminants. [53][54][55][56] Only few works reported this kind of approach by using more conventional photocatalysts such as titanium dioxide, zinc oxide, metal nanoparticles or hydrogen peroxide. [1,[57][58][59][60][61][62][63] We herein report an efficient and sustainable process for the degradation of azo dyes using a continuous flow microfluidic photoreactor, exploiting oxygen and fish waste-derived CDs as photocatalyst.…”
