Carbon monoxide chlorination

In electrochemical cells sample oxidation produces an electric current proportional to the concentration of test substance. Sometimes interferences by other contaminants can be problematic and in general the method is poorer than IR. Portable and static instruments based on this method are available for specific chemicals, e.g. carbon monoxide, chlorine, hydrogen sulphide.

Sulphuric acid (concentrated). Widely used in desiccators. Suitable for drying bromine, saturated hydrocarbons, alkyl and aryl halides. Also suitable for drying the following gases hydrogen, nitrogen, carbon dioxide, carbon monoxide, chlorine, methane and paraffins. Unsuitable for alcohols, bases, ketones or phenols. Also available with an indicator (a cobalt salt, blue when dry and pink when wet) under the name Sicacide (from Merck) for desiccators. 

Inorganic gases Oxides of nitrogen Oxides of sulfur Other inorganics Nitrogen dioxide, nitric oxide Sulfuric acid, sulfur dioxide Carbon monoxide, chlorine, ozone, hydrogen sulfide, hydrogen fluoride, ammonia One of the principal pollutants is sulfur dioxide, which is a corrosive acid gas that combines with water vapor in the atmosphere to produce acid rain. 

There are many air pollutants, and the composition and level depend on several factors. Air pollutants cause a range of adverse health and environmental effects. These pollutants include ammonia, carbon dioxide, carbon disulfide, carbon monoxide, chlorine, cyanide and cyanide compounds, cyanogen, diborane, fluorine and flourine... 

With the catalytic ozone analyzer described, ozone concentration can be measured by the temperature differential between two thermistors placed in the gas stream. One of the thermistors is coated with a catalyst promoting the decomposition of ozone the other is uncoated and is used as reference to the temperature of the gas. The two thermistors are part of a bridge circuit, the output of which is fed directly to a recorder. The instrument is not affected by the presence of water vapor, carbon monoxide, chlorine, nitrogen dioxide, sulfur dioxide, organic peroxides, hydrocarbon vapors, and combustion smokes at their usual concentrations in polluted atmospheres. 

However, in the case of oil-fired stoves, it is more likely that dichloromethane vapour is mixed with the air used for the burning of the oil, and the vapour therefore passes through the flames and comes into contact with carbon monoxide. Chlorine, formed by decomposition of CHjClj, then reacts with the CO to form phosgene, and in ill-ventilated rooms dangerous concentrations of COClj can accumulate [747]. 

CARBON OXYCHLORIDE (75-44-5) COCI2 Highly toxic and corrosive gas. Deconqioses slowly with water, producing hydrochloric acid and carbon oxides. Deconqjoses above 572°F/300°C, forming toxic and corrosive gases of hydrogen chloride and carbon monoxide chlorine. Reacts violently with strong oxidizers, amines, alkalis, anhydrous ammonia, isopropanol, chemically active metals aluminum, silicon tetrahydride, sodium. Forms shock-sensitive material with potassium. Incompatible with tert-alcohols. 

DINITROGEN MONOXIDE (10024-97-2) May form explosive mixture with flammable and reactive gases, including anhydrous ammonia, carbon monoxide, chlorine trifluoride, hydrogen, hydrogen sulfide, nitryl fluoride, phosphine. Nonflammable but supports combustion as temperature increases above 572°F/300°C, it becomes both a strong oxidizer and self-reactive. Pyrophoric at elevated temperatures. Reacts, possibly violently, with aluminum, ammonia, boron, hydrazine, lithium hydride, sodium, tungsten carbide.
