And the article was included in Journal of Hazardous Materials in 2009.Recommanded Product: 14070-51-0 This article mentions the following:
High surface area (887.3 m2/g) silica nanoparticles were synthesized using aerogel route and thereafter, characterized by N-Brunauer-Emmet-Teller (BET), SEM and TEM techniques. The data indicated the formation of nanoparticles of silica in the size range of 24-75 nm with mesoporous characteristics. Later, these were impregnated with reactive chems. such as N-chloro compounds, oxaziridines, polyoxometalates, etc., which have already been proven to be effective against sulfur mustard (HD). Thus, developed novel mesoporous reactive sorbents were tested for their self-decontaminating feature by conducting studies on kinetics of adsorptive removal of HD from solutions Trichloroisocyanuric acid impregnated silica nanoparticles (10%, weight/weight)-based system was the best with least half-life value (t1/2 =2.8 min) among prepared systems to remove and detoxify HD into nontoxic degradation products. Hydrolysis, dehydrohalogenation and oxidation reactions were the route of degradation of HD over prepared sorbents. The study also inferred that 10% loading of impregnants over high surface area and low d. silica nanoparticles enhances the rate of reaction kinetics and seems to be useful in the field of heterogeneous reaction kinetics. In the experiment, the researchers used many compounds, for example, 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0Recommanded Product: 14070-51-0).
2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Recommanded Product: 14070-51-0
