Hydrogen chloride phosgene

Hydrogen chloride, phosgene, irritating and toxic fumes and gases, hydrogen gas, and hydrogen gas. 

Carothers claimed that he kept going only because he finally received one of Illinois few scholarships, 750 embellished with esteem. But he must also have persevered because he loved chemistry. As he admitted, even the smell of his laboratory coat, saturated with the inexpressibly pungent and complicated odors of lab no. 219 [filled him] with a nostalgia to return to the atmosphere of sweetly blended sulfur dioxide, bromine, chlorine, ammonia, hydrogen chloride, phosgene, chloroacetone, etc., etc., etc. ... 

It is known that alumina is chlorinated exothermically at above 200° C by contact with halocarbon vapours, and hydrogen chloride, phosgene etc. are produced. It has now been found that a Co/Mo-alumina catalyst will generate a substantial exotherm in contact with vapour of carbon tetrachloride or 1,1,1-trichloroethane at ambient temperature in presence of air. In absence of air, the effect is less intense. Two successive phases appear to be involved first, adsorption raises the temperature of the alumina then reaction, presumably metal-catalysed, sets in with a further exotherm. 

Determine (a) whether the following chemicals are covered under the PSM regulation (29 CFR 1910.119) and (b) their threshold quantities acrolein, hydrogen chloride, phosgene, propane, ethylene oxide, and methanol. 

Boron trichloride can be prepared by high temperature chlorination of boron trioxide, boric acid, metal borates or other boron compounds. Chlorine, hydrogen chloride, phosgene, silicon tetrachloride, metal chlorides, carbon... 

A package of this, consisting of a wax-coated glass jar in vermiculite within a sealed can, was found to be pressurised when opened. The cap of the jar had cracked, and it was assumed that residual water on the vermiculite had reacted to form hydrogen chloride, phosgene and carbon dioxide. Similar mishaps had been experienced... 

CNS depression, cardiac arrythmias, respiratory depression, and death. Halo-genated hydrocarbons decompose when heated and become a toxic gas (e.g., hydrogen chloride, phosgene). Evaporation of halogenated hydrocarbons as propellants causes intense cold, which leads to numbness. These gases have been used as topical analgesics.
