Neatu, Stefan published the artcilePhotodegradation of yperite over V, Fe and Mn-doped titania-silica photocatalysts, Name: 1,2-Bis(2-chloroethyl)disulfane, the publication is Physical Chemistry Chemical Physics (2008), 10(43), 6562-6570, database is CAplus and MEDLINE.

The photocatalytic decomposition of Yperite (bis(2-chloroethyl)sulfide), a chem. warfare agent, was achieved by using titania-silica catalysts doped with several transition metal ions. The preparation of these catalysts was achieved by impregnation of a titania-silica mixed oxide previously synthesized using a sol-gel route with salts of the doping elements (vanadium, iron, manganese). The above catalysts were characterized using several spectroscopic techniques: FTIR, Raman, DR-UV-Vis, and XPS. The band gap energy was measured for each photocatalytic system. The reaction was carried out in two different types of reactors, i.e. naturally aerated and a closed quartz tube aerated under a constant flow, and using two types of irradiation, UV-Vis and Vis. The investigated systems proved to be extremely active, leading to an almost complete degradation of yperite in 2 h of irradiation An excellent correlation between the photocatalytic performances and the band gap has been found. Based on the characterization data and on the temporal evolution of the reaction products, a reaction mechanism has been suggested. This mechanism considers two distinct pathways for the decomposition of yperite, namely the C-S bond cleavage and the S oxidation

Hanaoka, Shigeyuki published the artcileDetermination of mustard and lewisite related compounds in abandoned chemical weapons (Yellow Shells) from sources in China and Japan, Application In Synthesis of 1002-41-1, the publication is Journal of Chromatography A (2006), 1101(1-2), 268-277, database is CAplus and MEDLINE.

Knowledge of the states of the contents in chem. munitions that Japanese Imperial Forces abandoned at the end of World War II in Japan and China is gravely lacking. To unearth and recover these chem. weapons and detoxify the contents safely, it is essential to establish anal. procedures to definitely determine the CWA contents. We established such a procedure and applied it to the anal. of chems. in the abandoned shells. Yellow shells are known to contain sulfur mustard, lewisite, or a mixture of both. Lewisite was analyzed without thiol derivatization, because it and its decomposition products yield the same substances in the derivatization. Anal. using our new procedure showed that both mustard and lewisite remained as the major components after the long abandonment of ∼60 yr. The content of mustard was 43% and that of lewisite 55%. The viscous material found was suggested to be mostly oligomers of mustard. Comparison of the components in the Yellow agents with mustard recovered in both Japan and China showed a difference in the impurities between the CWAs produced by the former Imperial navy and those by the former Imperial army.

Water-insoluble pyridinium-based ionic liquids with a disulfide bond were prepared Reduction of these ionic liquids using sodium hydrosulfite changed the water solubilities of the ionic liquids because the structural exchange of disulfide into thiol groups increased their polarities. Such a structural change by oxidation-reduction enabled reversible control of the phase separation property of ionic liquids with water.

Hoejer Holmgren, Karin published the artcileRoute Determination of Sulfur Mustard Using Nontargeted Chemical Attribution Signature Screening, Safety of 1,2-Bis(2-chloroethyl)disulfane, the publication is Analytical Chemistry (Washington, DC, United States) (2021), 93(11), 4850-4858, database is CAplus and MEDLINE.

Route determination of sulfur mustard was accomplished through comprehensive nontargeted screening of chem. attribution signatures. Sulfur mustard samples prepared via 11 different synthetic routes were analyzed using gas chromatog./high-resolution mass spectrometry. A large number of compounds were detected, and multivariate data anal. of the mass spectrometric results enabled the discovery of route-specific signature profiles. The performance of two supervised machine learning algorithms for retrospective synthetic route attribution, orthogonal partial least squares discriminant anal. (OPLS-DA) and random forest (RF), were compared using external test sets. Complete classification accuracy was achieved for test set samples (2/2 and 9/9) by using classification models to resolve the one-step routes starting from ethylene and the thiodiglycol chlorination methods used in the two-step routes. Retrospective determination of initial thiodiglycol synthesis methods in sulfur mustard samples, following chlorination, was more difficult. Nevertheless, the large number of markers detected using the nontargeted methodol. enabled correct assignment of 5/9 test set samples using OPLS-DA and 8/9 using RF. RF was also used to construct an 11-class model with a total classification accuracy of 10/11. The developed methods were further evaluated by classifying sulfur mustard spiked into soil and textile matrix samples. Due to matrix effects and the low spiking level (0.05% weight/weight), route determination was more challenging in these cases. Nevertheless, acceptable classification performance was achieved during external test set validation: chlorination methods were correctly classified for 12/18 and 11/15 in spiked soil and textile samples, resp.

An efficient and operationally simple method for the chem. decontamination of sulfur mustard has been reported herein. A newly synthesized (pos. chlorine bearing) reagent N,N-dichlorovaleramide has been utilized for this purpose. Decontamination has been achieved in aqueous and aprotic media. The reaction was monitored by gas chromatog.-mass spectrometry and NMR spectroscopy. This reagent is more effective, stable, economical, and easy to synthesize and leads to instant decontamination of sulfur mustard. The reaction was found to instantaneously and completely convert sulfur mustard to innocuous products at different temperatures (-10 to 25 °C).

Photocatalytic oxidation of gaseous 2-chloroethyl Et sulfide (2-CEES) over TiO₂ illuminated with UV light and maintained at 25° or 80° in air has been investigated. 2-CEES was found to suffer progressive oxidation to yield ethylene, chloroethylene, ethanol, acetaldehyde, chloroacetaldehyde, di-Et disulfide, 2-chloroethyl Et disulfide, and bis(2-chloroethyl) disulfide as the main primary intermediates, and water, carbon dioxide, sulfur dioxide, surface sulfate ions, and hydrogen chloride as the final products. Trace concentrations of gaseous 2-chloroethanol, ethanesulfonyl chloride, Et thioacetate, and considerable amounts of acetic acid, crotonaldehyde, Me acetate, and Me formate were also detected in the gas phase during the photooxidation conducted at 80°. An increase in temperature from 25° to 80° accelerates formation of gaseous ethanol, acetaldehyde, chloroacetaldehyde, di-Et disulfide, 2-chloroethyl Et disulfide, and bis(2-chloroethyl) disulfide but suppresses ethylene and chloroethylene production at initial stages of the process. Some aspects of the possible reaction mechanism leading to this wide array of intermediates and final products are discussed.
