Hydrogen sulfide phosgene

Class 2 Gases such as chlorine, hydrogen bromide, hydrogen cliloride, hydrogen fluoride, hydrogen sulfide, phosgene, sulfur dioxide. 

Fatal if inhaled 2 Danger > 100 to <500 ppm (gas) > 0.5 to <2.0 mg/L (vapor) > 0.05 to <0.5 mg/L (dust, mist) Acrylonitrile, anihne, boron tiifluoiide, chlorine, diazomethane, fluorine, formaldehyde, hydrogen sulfide, phosgene... 

Hazard. Most of the products, intermediates, and by-products in this cat ory are highly flammable, and some are toxic (e.g., hydrogen cyanide, hydrogen sulfide, phosgene). Some can form explosive vapor clouds upon release. 

Lethai fluids. Such as hydrogen sulfide, phosgene, hydrogen Qranide, lol bromide, etc. Normally in vertical units, can be all welded (no gaskets anywhere) if preferred. Usually 100 percent radiographically inspected and heat treated after fabrication. Also available as heavy duty shell design with removable bundles. 

Bromodichloronitrosomethane. BrCCl2NO, mw 192.84, N 7.26% it is a dark blue liq of unpleasant odor, fr p -80° bp 21° at 24mm. It is prepd by the action of Br and Na acetate on phosgene oxime (C CiNOH). It decomps on attempted distn at atm press. It is reduced to phosgene oxime with hydrogen sulfide in Me ale, and warming with Br produces dichlorodibromo-methane... 

It should be noted that space permits only one sample of District Chief Armando Bevelac-qua work. However, his production also includes medical protocols for Bronchospasms, Tachydysrhythmias, Chemical Burns, Carbon Monoxide, Nitrogen Compounds, Cyanide and Hydrogen Sulfide, Organophosphate and Carbamate (Nerve Agents), Hydrofluoric Acid, Phenol, Chloramine and Chlorine Products, Lacrimators, and Phosgene. 

Chemical Properties. Thiophosgene is more resistant to hydrolysis than its oxygen analogue, phosgene, but it is slowly hydrolyzed to carbon dioxide, hydrogen sulfide, and hydrochloric acid. It can be oxidized to a lacrimatory thiophosgene 5-oxide (41). Its utility in organic synthesis has been... 

Hydrogen sulfide does not react with phosgene in the cold [184a]. However, upon... 

Addition of hydrogen sulfide (0.5 molar equivalent) to cyclopropanone in dichloromethane afforded the bis-adduct 1, which could be spirocyclized with excess phosgene in the presence of pyridine to give 8,10-dioxa-4-thiadispiro[2.1.2.3]decan-9-one (2). Thermolysis of this cyclic carbonate at 495°C in vacuo (0.5 Torr) yielded methylenethiirane 3, an elusive species in the methyleneheteracyclopropane series. 

New Jersey adopted a Toxic Catastrophe Prevention Act in 1986, which requires risk assessment by companies.167 The Kanawha Valley Hazardous Assessment Project in West Virginia developed worst-case scenarios for 12 chemical plants in the area.168 The chemicals studied included acrylonitrile, vinylidene chloride, butyl isocyanate, methylene chloride, chlorine, phosphorus trichloride, hydrogen sulfide, methyl isocyanate, phosgene, ethylene oxide, sulfur trioxide, and others...
