Abstract

The sulfur-containing chemical warfare agents sulfur mustard HD and nerve agent VX are highly toxic and persistent in the environment. Therefore, their neutralisation requires harsh oxidation conditions, but also precise selectivity. Here we report the safe and effective detoxification of surrogates CEES and PhX by selective oxidation of the sulfur atom by generating peracetic acid from AcOEt and aq. H2O2 assisted by the supported lipase CALB. Morever, it is possible to perform these neutralisations with safe 'on demand' generation of AcOOH in a flow system by using a packed bed reactor containing the supported biocatalyst.

期刊介绍: Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields. Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world. All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times. The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems. Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
