    CARBON TETRACHLORIDE 1 1. PUBLIC HEALTH STATEMENT This public health statement tells you about carbon tetrachloride and the effects of exposure to it. The Environmental Protection Agency (EPA) identifies the most serious hazardous waste sites in the nation. These sites are then placed on the National Priorities List (NPL) and are targeted for long-term federal clean-up activities. Carbon tetrachloride has been found in at least 430 of the 1,662 current or former NPL sites. Although the total number of NPL sites evaluated for this substance is not known, the possibility exists that the number of sites at which carbon tetrachloride is found may increase in the future as more sites are evaluated. This information is important because these sites may be sources of exposure and exposure to this substance may harm you. When a substance is released either from a large area, such as an industrial plant, or from a container, such as a drum or bottle, it enters the environment. Such a release does not always lead to exposure. You can be exposed to a substance only when you come in contact with it. You may be exposed by breathing, eating, or drinking the substance, or by skin contact. If you are exposed to carbon tetrachloride, many factors will determine whether you will be harmed. These factors include the dose (how much), the duration (how long), and how you come in contact with it. You must also consider any other chemicals you are exposed to and your age, sex, diet, family traits, lifestyle, and state of health.

  • Ozone Depleting Substances
    Ozone Depleting Substances What are they? Ozone depleting substances are chemicals that destroy the earth’s protective ozone layer. They include: • chlorofluorocarbons (CFCs) • halons • carbon tetrachloride (CCl4) • methyl chloroform (CH3CCl3) • hydrobromofluorocarbons (HBFCs) • hydrochlorofluorocarbons (HCFCs) • methyl bromide (CH3Br) • bromochloromethane (CH2BrCl) The use of these chemicals is controlled by the Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol). There are other ozone depleting substances, but their ozone depleting effects are very small, so they are not controlled by the Montreal Protocol. One kilogram of halon 1211 can destroy 50 tonnes of ozone What is ozone depleting potential? Ozone depleting potential is a measure of how much damage a chemical can cause to the ozone layer compared with a similar mass What did we use ozone depleting of trichlorofluoromethane (CFC-11).

  • Carbon Tetrachloride Poisoning Patient Education and Care
    Carbon Tetrachloride Poisoning Patient Education and Care Instruction Sheet Overview of Carbon tetrachloride (CCl4) is a manufactured chemical. It Carbon does not occur naturally, but it is present in the Tetrachloride environment because it does not break down very easily and has built up over time from human activities. CCl4 is a clear liquid that evaporates into the air easily. It has a sweet odor that can be smelled at low levels. CCl4 is most often found in the air as a colorless gas. CCl4 is not flammable and does not dissolve very easily in water. CCl4 was previously used • In the production of refrigeration fluid and propellants for aerosol cans, • As a pesticide, • As a cleaning fluid and degreasing agent, • In fire extinguishers, and • In spot removers. Due to the harmful health effects from exposure, consumer uses of CCl4 were discontinued in the mid- 1960s and pesticide uses were stopped in 1986. However, use of older products that might contain CCl4 or use of household cleaning products containing bleach that might produce carbon tetrachloride have been reported since 1986. Only industrial and research uses remain in the United States. How Can Very low levels (called background levels) of CCl4 can be People Be found in Exposed to Carbon • Air, Tetrachloride? • Water, and • Soil. 1 Exposure to levels of CCl4 higher than background levels is likely to occur • At work in specific industrial locations where CCl4 is still used or • Near chemical waste sites where emissions into air, water, or soil are not properly controlled. Some ways that CCl4 can get into the body include • Breathing CCl4 present in the air, • Drinking water or eating food contaminated with CCl4, • Getting CCl4 liquid spilled on skin, or • Getting CCl4 contaminated soil or water on the skin.

  • Toxicological Profile for Carbon Tetrachloride
    CARBON TETRACHLORIDE 175 5. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL 5.1 PRODUCTION Carbon tetrachloride is produced by exhaustive chlorination of a variety of low molecular weight hydrocarbons such as carbon disulfide, methane, ethane, propane, and ethylene dichloride (HSDB 2004). It is also produced by thermal chlorination of methyl chloride (HSDB 2004). Carbon tetrachloride is a feedstock for chlorofluorocarbon gases, such as dichlorodifluoromethane (F-12) and trichlorofluoro­ methane (F-11), which were used as aerosol propellants in the 1950s and 1960s (Holbrook 1991). Following this, the growth rate for the production of carbon tetrachloride averaged 10.7% per year from 1960 to 1970 (Holbrook 1991). This rate slowed to 7.2% per year from 1970 to 1974, when the production of this chemical was at its peak, as other forms of propellants became commercially available (Anonymous 1981; Holbrook 1991). The FDA banned the sale of carbon tetrachloride in any product used in the home and the EPA regulated the use of chlorofluorocarbon gases as aerosols or propellants. Since then, production of carbon tetrachloride has declined at approximately 8% a year from 1974 to 1994 (Anonymous 1995; Holbrook 1991). Carbon tetrachloride is currently manufactured in the United States by Vulcan Materials Company at two plants: Geismar, Louisiana and Wichita, Kansas, with a combined 130 million pound capacity (HSDB 2004; SRI 2004). It should be noted, however, that these capacities are flexible, since other chlorinated solvents are made using the same equipment (SRI 2004). This recent decline in production is due to the adoption of an international agreement (the Montreal Protocol) to reduce environmental concentrations of ozone-depleting chemicals (including carbon tetrachloride), and to the provisions of Title VI of the Clean Air Act Amendments of 1990 addressing these chemicals.

  • Carbonyl-Phosphine Hetero-Ligated Half-Metallocene Iron(II) Catalysts for Living Radical Polymerization: Concomitant Activity and Stability
    Polymer Journal (2010) 42, 17–24 & The Society of Polymer Science, Japan (SPSJ) All rights reserved 0032-3896/10 $32.00 www.nature.com/pj INVITED ARTICLE Carbonyl-phosphine hetero-ligated half-metallocene iron(II) catalysts for living radical polymerization: concomitant activity and stability Muneki Ishio, Takaya Terashima, Makoto Ouchi and Mitsuo Sawamoto Two neutral ligands, carbonyl (CO) and phosphine, were cooperatively incorporated into half-metallocene iron(II) complexes (CpFeBr(CO)(PR3); Cp¼C5H5;PR3¼PPh3, P(OPh)3, PMePh2, PMe2Ph, P(n-Bu)3) for more active and versatile systems in transition metal-catalyzed living radical polymerization. For methyl methacrylate (MMA) with a bromide initiator [Me2C(CO2Me)CH2C(Me)-(CO2Me)Br; Me¼CH3] [H-(MMA)2-Br], these hetero-ligated catalysts are superior, in terms of catalytic activity and molecular weight control, to similar homo-ligated half-metallocenes carrying two identical ligands such as CpFeBr(CO)2 and CpFeBr(PR3)2. Among the CpFeBr(CO)(PR3) complexes examined, CpFeBr(CO)(PMePh2) showed the highest activity and the best controllability (490% conversion within 24 h; Mw/Mn¼1.29), and the ‘living’ character of the polymerizations therewith was proved by sequential monomer addition experiments. In spite of the high activity, the Fe(II) complex is stable and robust enough to be handled under air, rendering it suitable for practical use. The concomitant high activity and high stability were attributed to the in situ generation of a real active catalyst with a 16-electron configuration by the irreversible release of the CO group from CpFeBr(CO)(PR3) on the activation of a terminal C–Br bond, as confirmed by the Fourier transform infrared monitoring of model reactions with the initiator as a dormant-end model compound.
