일반 설명

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.

반응 프로필

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)].

건강위험

Prolonged exposure can cause narcotic effect or rapid suffocation.

화재위험

Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.

Safety Profile

An asphyxiant. See also DICHLOROTETRAFLUOROETHANE

잠재적 노출

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).

운송 방법

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

비 호환성

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.

폐기물 처리

Return refillable compressed gas cylinders to supplier. Incineration after mixing with combustible fuel. Use flue gas scrubber.
