| | 1,2-DICHLOROTETRAFLUOROETHANE Usage And Synthesis |
| Chemical Properties | colourless gas | | Chemical Properties | CFC 114 is a colorless gas with a faint, ethereal odor at high concentrations. A liquid below
3.3_x0003_°C/38°F. Shipped as a liquefied compressed gas | | Uses | Please view www.aldrich.com/epaods regarding the EPA′s request for application information of Ozone Depleting Substances | | Uses | bronchodilator, decongestant | | Uses | Refrigerant, aerosol propellant. | | General Description | 1,2-DICHLOROTETRAFLUOROETHANE is a colorless, nearly odorless nonflammable gas. 1,2-DICHLOROTETRAFLUOROETHANE may be mildly toxic and irritating by inhalation. 1,2-DICHLOROTETRAFLUOROETHANE can asphyxiate by the displacement of air. Exposure of the container to prolonged heat or fire can cause 1,2-DICHLOROTETRAFLUOROETHANE to rupture violently and rocket. 1,2-DICHLOROTETRAFLUOROETHANE is used as a solvent and as a fire extinguishing agent. | | Reactivity Profile | 1,2-DICHLOROTETRAFLUOROETHANE is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. Can react with strong oxidizing agents or weaker oxidizing agents under extremes of temperature. The reaction of aluminum with various halogenated hydrocarbons produces a self-sustaining reaction with sufficient heat to melt aluminum pieces, examples of other halogenated hydrocarbons are fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane. The vigor of the reaction appears to be dependent on the combined degree of fluorination and the vapor pressure, [Chem. Eng. News 39(27):44(1961)]. | | Health Hazard | Prolonged exposure can cause narcotic effect or rapid suffocation. | | Fire Hazard | Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket. | | Safety Profile | An asphyxiant. See also
DICHLOROTETRAFLUOROETHANE | | Potential Exposure | This material is used as a refrigerant
and also as a propellant gas | | Carcinogenicity | Dichlorotetrafluoroethane is considered to
have little or no mutagenic or carcinogenic
potential.
The 2003 ACGIH threshold limit
value-time-weighted average (TLV-TWA)
for dichlorotetrafluoroethane is 1000ppm
(6990mg/m3). | | Shipping | UN1958. 1,2-Dichloro-1,1,2,2-tetrafluoroethane
or Refrigerant gas R-114, Hazard Class: 2.2; Labels: 2.2-
Nonflammable compressed gas. Cylinders must be transported in a secure upright position, in a well-ventilated
truck. Protect cylinder and labels from physical damage.
The owner of the compressed gas cylinder is the only entity
allowed by federal law (49CFR) to transport and refill
them. It is a violation of transportation regulations to refill
compressed gas cylinders without the express written permission of the owner | | Incompatibilities | Keep away from welding and hot
metals; decomposes, forming hydrogen chloride and
hydrogen fluoride. Reacts with acids and acid fumes forming highly toxic chloride gases. Keep away from chemically active metals: sodium, potassium, calcium,
powdered aluminum; zinc, and magnesium. Attacks some
plastics and coatings. | | Waste Disposal | Return refillable compressed
gas cylinders to supplier. Incineration after mixing with
combustible fuel. Use flue gas scrubber. |
