    Chlorine 7782-50-5 Hazard Summary Chlorine is a commonly used household cleaner and disinfectant. Chlorine is a potent irritant to the eyes, the upper respiratory tract, and lungs. Chronic (long-term) exposure to chlorine gas in workers has resulted in respiratory effects, including eye and throat irritation and airflow obstruction. No information is available on the carcinogenic effects of chlorine in humans from inhalation exposure. A National Toxicology Program (NTP) study showed no evidence of carcinogenic activity in male rats or male and female mice, and equivocal evidence in female rats, from ingestion of chlorinated water. EPA has not classified chlorine for potential carcinogenicity. Please Note: The main sources of information for this fact sheet are EPA's Integrated Risk Information System (IRIS) (2), which contains information on oral chronic toxicity and the RfD, The California Environmental Protection Agency's (CalEPA's) Technical Support Document for the Determination of Noncancer Chronic Reference Exposure Levels (3), and EPA's Drinking Water Criteria Document for Chlorine, Hypochlorous Acid and Hypochlorite Ion (1). Uses Chlorine is a commonly used household cleaner and disinfectant. It is widely used as an oxidizing agent in water treatment and chemical processes. It is also used in the bleaching process of wood pulp in pulp mills. (8) Sources and Potential Exposure Workers may be exposed to chlorine in industries where it is produced or used, particularly in the food and paper industries. In addition, persons breathing air around these industries may be exposed to chlorine. (1) Exposure to chlorine may also occur through drinking water and swimming pool water, where it is used as a disinfectant.

We report here the first kinetics measurements of the reactions of atomic chlorine with 4-chlorocrotonaldehyde and chloromethyl vinyl ketone, recently identified as products of the reaction of chlorine atoms with 1,3-butadiene. The reactions with acrolein, methacrolein, crotonaldehyde, methyl vinyl ketone and crotyl chloride were also studied to probe structure- reactivity relationships. Relative rate studies were carried out at 1 atm and 298 K using two different approaches: long path FTIR for the acrolein, methacrolein, crotonaldehyde and methyl vinyl ketone reactions with acetylene as the reference compound, and a collapsible Teflon reaction chamber with GC-FID detection of the organics using n-butane or n-nonane as the reference compounds for the entire series.

  • Chlorine What Is Chlorine?
    Chlorine What is Chlorine? Chlorine is an element found frequently in nature. By itself, it is usually found as chlorine gas (Cl2). It can also be found in a variety of common chemicals, from table salt (sodium chloride) to household bleach (sodium hypochlorite) to hydrochloric acid (hydrogen chloride). Chlorine and the closely related chloramine gas can also be accidentally formed when cleaners like ammonia and bleach are mixed together. What is chlorine used for? Chlorine has a variety of uses in industry and chemistry. It can be found in processes to make paper, solvents, insecticides, paints, medicines, plastics, and textiles. It is also used to purify water supplies and pools. Is chlorine gas harmful? At significant concentrations, yes. Chlorine gas will react with the water in human tissues to form hydrochloric acid, which is very irritating to the airways, lungs, and eyes. What are the signs of a chlorine gas exposure? Chlorine is very irritating to the throat and lungs and will cause a burning sensation with coughing and difficulty breathing. Chlorine gas can also be irritating to the eyes. Are there long term effects from chlorine gas exposures? The long term effects from a single exposure are related to the duration of the exposure and its severity. Some people will continue to experience a persistent cough and chest tightness, potentially even for years. What should I do if I think I have been exposed to chlorine gas? The most important thing you can do is to get out of the area immediately and to a safe place with fresh air.

  • CHLORINE Public Fact Sheet What Is Chlorine? Chlorine Is a Naturally Occurring Element Normally Used in Industry and Found in Some Household Products
    Revised January 2004 CHLORINE Public Fact Sheet What is chlorine? Chlorine is a naturally occurring element normally used in industry and found in some household products. It is normally found as a greenish-yellow gas with a strong, irritating odor like household bleach. Chlorine gas can also be stored under pressure as a liquid for transportation and storage. Although chlorine gas is not flammable, it reacts explosively with many common chemicals (such as alcohols, ammonia, and gasoline) and may ignite some objects (such as wood, paper, oil, and clothing). DO NOT mix household bleach with acid-containing or ammonia-containing household chemicals (drain cleaners, ammonia, cleansers). Dangerous amounts of chlorine or other toxic gases can be released. How is chlorine used? Chlorine gas was the first chemical warfare agent to be used on a large scale during World War I. Today, chlorine is one of the most commonly used industrial chemicals. It is used as an ingredient in the production of some solvents, as a bleaching agent in paper and cloth production, as an agent to kill bacteria in drinking and swimming pool water, and as part of the sanitation process for industrial waste and sewage. How can people be exposed to chlorine? Significant exposure is usually associated with industrial processes or accidental spills. Most direct releases of chlorine to the environment are into air and/or water. Chlorine will react with other chemicals once it is released to air or water to form more stable compounds. It can enter groundwater if it is the form of one of these more stable compounds.

    First-Principle Study of Phosphine Adsorption on Si(001)-2×1-Cl Tatiana V. Pavlova1,2,∗ Georgy M. Zhidomirov1,2, and Konstantin N. Eltsov1,2 1Prokhorov General Physics Institute of the Russian Academy of Sciences, Moscow, Russia and 2National Research University Higher School of Economics, Moscow, Russia This paper presents a DFT study for phosphine adsorption on a Si(001)-2×1 surface covered by a chlorine monolayer, including adsorption on local defects, i.e. mono- and bivacancies in the adsorbate layer (Cl, Cl2), and combined vacancies with removed silicon atoms (SiCl, SiCl2). Activation barriers were found for the adsorbing PH3 to dissociate into PH2+H and PH+H2 fragments; it was also established that phosphine dissociation on combined vacancies is possible at room temperature. If there is a silicon vacancy on the surface, phosphorus settles in the Si(001) lattice as PH (if the vacancy is SiCl) or as PH2 (if the vacancy is SiCl2). This paper suggests a method to plant a separate phosphorus atom into the silicon surface layer with atomic precision, using phosphine adsorption on defects specially created on a Si(001)-2×1-Cl surface with an STM tip.

    Phosgene 2 Gases 44P make Hydrogen website Tear Gas,2 KCN 2, make somoom Chemical Agents Chlorine pwdr Ricin CHLORINE,2 Sugar water Phosgene Phosgene, also known as carbonic dichloride, colorless, extremely toxic gas of formula COCl2 with an unpleasant, irritating odor at high concentrations. It is prepared by the reaction of carbon monoxide with chlorine in the presence of a catalyst. Phosgene is poisonous in concentrations above 50 parts per million of air, and if inhaled, it causes severe and often fatal edema of the lungs within a few hours. It was used in World War I as a poison gas but today is used principally as an intermediate in the synthesis of organic compounds, including carbonic esters, isocyanates, polyurethanes, and dyes. Phosgene is 3.43 times heavier than air; the gas melts at -118° C (-180.4° F) and boils at 8.3° C (46.9° F). Look here Chemical war section. Tear Gas I INTRODUCTION Tear Gas, chemical substance that produces a primary physical effect of stinging or tearing eyes. Tear gas also irritates other mucous membranes and causes choking and coughing. People exposed to higher concentrations may experience burning, itching, or even blistering skin. As a form of riot control, police often use clouds of tear gas to break up crowds of people. A rifle-fired grenade or a thrown canister usually delivers tear gas, but smaller hand- held spray devices also exist. Tear gas may also be used to force the surrender of fugitives hiding in a building. Dogs and horses are relatively unaffected by tear gas, so they can add to the riot-control effect of the gas.
