Thus, this type of preparation cannot be used to prepare a pure CaS salt. Calcium sulfide is available commercially as the pure sulfide as well as the polysulfide due to its extensive usage in the past as an insecticide both agriculturally and in home gardens. View all General Description ...
Sodium tungstate and sodium sulfide are mixed and dissolved in water, and then zinc chloride aqueous solution is added, filtered, and the filtrate is treated with pure calcium chloride to prepare calcium tungstate. View all 3.3 Usage Calcium tungstate can be ued for preparing screens for x-ray...
What is the chemical formula for the compound tetraphosphorus decasulfide? What is given by parentheses in a compound chemical formula? What is the formula of the hydride formed by tellurium? What is the name for the compound with the formula MgCl_2?
We found that when AtPXG1 was incubated in the presence of methyl p-tolyl sulfide and cumene hydroperoxide as an oxygen donor, the (S)-sulfoxide was formed with ∼60% enantiomeric excess. If oleic acid was used as substrate instead of sulfide, AtPXG1 produced cis-9,10-epoxystearic acid...
as well as the formation of reactive species (Cl, Cl2, Cl2O, O, S, and SCl2) through the reactions of HCl with Fe2O3and CaSO4in HICCA. The formation of C–Cl bond is not the main pathway for the promotional effect of HCl on Hg0removal. SO2played a negative role in Hg0removal ...
It encompasses (a) substrate ring-opening with pyrrolidine/AgNO3, (b) trapping of the intermediate silver sulfide with a suitable halide, (c) replacement of the pyrrolidino moiety with the aryl of a Grignard reagent, (d) oxidation of sulfur, and (e) cyclization to the final thiopyran (5)...
Enrofloxacin (EFX) reacting with Ca(II) afforded a new complex, [Ca(EFX)2(H2O)4] (EFX-Ca), which was structurally characterized both in solid and solution chemistry. E. coli and S. typhi were tested to be the most sensitive strains for EFX-Ca. The LD50 v
