Trichlorofluoromethane Usage And Synthesis

Chemical Properties

colourless liquid

Chemical Properties

Fluorotrichloromethane is a colorless liquid or gas. Chlorinated solvent odor. The Odor Threshold is 5.0 ppm.

Uses

In refrigeration machinery requiring a refrigerant effective at negative pressures. As aerosol propellant.

Definition

ChEBI: A one-carbon compound that is methane in which the hydrogens have been replaced by three chlorine and one fluorine atom.

General Description

A clear light colored liquid. Nearly odorless. Denser than water. Poses low acute health hazard to humans. Primary hazard is to the environment. Immediate steps should be taken to limit spread to the environment. Easily penetrates the soil to contaminate groundwater and nearby waterways.

Air & Water Reactions

Water soluble. Hydrolyzed slowly.

Reactivity Profile

Trichlorofluoromethane is incompatible with alkali or alkaline earth metals, powdered aluminum, zinc and beryllium. Trichlorofluoromethane reacts violently with barium and lithium.

Health Hazard

Breathing concentrations approaching 10% in air will cause dizziness and drowsiness. Contact with tissues may cause frostbite.

Fire Hazard

Special Hazards of Combustion Products: Produces irritating and toxic products when heated to decomposition temperatures.

Chemical Reactivity

Reactivity with Water: No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Safety Profile

High concentrations cause narcosis and anesthesia in humans. Human systemic effects by inhalation: conjunctiva irritation, fibrosing alveolitis, and liver changes. Experimental poison by inhalation. Moderately toxic by intraDeritoneal route. Reacts violentlv with I aluminum, barium, or lithium. When heated to decomposition it emits highly toxic fumes of Fand Cl-. Used as an aerosol propellant, refrigerant, and blowing agent for polymeric foams. See also CHLORINATED HYDROCARBONS, ALIPHATIC; and FLUORIDES.

Potential Exposure

This material is used as a refrigerant; aerosol propellant; and foaming agent; as blowing agent in production of polyurethane foams.

Carcinogenicity

When administered by gavage to groups of 50 male and 50 female mice at daily doses of 1962 or 3952mg/kg, 5 days/week for 78 weeks followed by a 13week observation period, there was no evidence of carcinogenicity. Also,when given to rats at daily doses of 488 and 977mg/kg for males and 538 and 1077mg/kg for females, again for 5 days/week for 78 weeks, but followed by a 28–33 week observation period, there was no evidence of carcinogenicity. Maltoni et al. exposed groups of 90 male and 90 female Sprague–Dawley rats and groups of 60 male and 60 female Swiss mice by inhalation to levels of 1000 and 5000 ppm 4 h/day, 5 days/week for life. The exposures did not produce evidence of carcinogenicity.

Environmental Fate

Biological. In a static-culture-flask screening test, trichlorofluoromethane was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum. No significant degradation was observed after 28 d of incubation. At substrate concentrations of 5 and 10 mg/L, percent losses due to volatilization were 58 and 37% after 10 d (Tabak et al., 1981).
Chemical/Physical. When trichlorofluoromethane (50 μg/L) in an ultrasonicator was exposed to 20-kHz ultrasound at 5 °C, nearly 100% degradation was achieved after 6 min. During sonication, the pH of the aqueous solution decreased, which is consistent with the formation of HCl, hydrofluoric acid, and acidic species from fluorine and chlorine. In this experiment <5% of trichlorofluoroethane was lost to volatilization (Cheung and Kurup, 1994).

Shipping

Hazard Class: 2.2; Labels: 2.2-Nonflammable compressed gas, Technical Name Required.

Incompatibilities

Chemically active and powdered metals: aluminum, barium, sodium, potassium, calcium, powdered aluminum; zinc, magnesium.

Waste Disposal

Incineration, preferably after mixing with another combustible fuel. Care must be exer cised to assure complete combustion to prevent the forma tion of phosgene. An acid scrubber is necessary to remove the halo acids produced. Consult with environmental regu latory agencies for guidance on acceptable disposal prac tices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations govern ing storage, transportation, treatment, and waste disposal.
