Packing: 200L iron drum 300kg/drum

Perchloroethylene, an organic compound, also known as perchloroethylene, is a compound formed by replacing all hydrogen atoms in ethylene with chlorine.

Tetrachloroethylene is an important organochlorine product, which is mainly used as organic solvent, dry cleaning agent, desulfurizer, fabric finishing agent, metal detergent, fat extractant, organic synthesis and heat transfer medium in industry. It is used as an anthelmintic agent and an intermediate of the refrigerant CFC-123.

Appearance and Properties: Colorless liquid with chloroform-like odor.

Log value of octanol/water partition coefficient: 2.88

Solubility: Insoluble in water, miscible in most organic solvents such as ethanol and ether.

It is a colorless transparent liquid with a odor similar to ether. Can dissolve a variety of substances (such as rubber, resin, fat, aluminum trichloride, sulfur, iodine, mercury chloride). It is miscible with ethanol, ether, chloroform and benzene. Soluble in about 10,000 times the volume of water.

Application

1. Tetrachloroethylene is widely used, mainly used as metal degreasing solvent, and also used as anthelmintic. Tetrachloroethylene can be used as fat extraction agent, fire extinguishing agent and smoke screen agent, etc. It can also be used to synthesize trichloroethylene and fluorine-containing organic compounds.

2. Widely used as a dry cleaning agent for natural and synthetic fibers. Also used as metal degreasing detergent and general solvent, organic synthesis intermediates, etc.

3. Used as a standard substance for chromatographic analysis.

4. Insect repellent and fat extractant for adhesives, and also used in organic synthesis.

Notes

health hazard

This product has stimulating and anesthetic effects. Inhalation of acute poisoning has upper respiratory tract irritation, tearing, salivation. Dizziness, headache, nausea, ataxia, and drunkenness-like symptoms ensue. After oral administration, dizziness, headache, drowsiness, nausea, vomiting, abdominal pain, blurred vision, numbness of the limbs, and even excitement, convulsions and even coma, can be fatal. Chronic Effects: Fatigue, dizziness, nausea, tinnitus, etc. Liver damage may occur. Repeated skin contact can cause dermatitis and eczema.

explosion hazard

This product is flammable, toxic and irritating, and generally does not burn, but it can still burn when exposed to open flame and high temperature for a long time. Decomposed by high heat to produce toxic corrosive gas. Reacts with active metal powders (such as magnesium, aluminum, etc.) to cause decomposition. In case of high heat, violent decomposition may occur, causing container rupture or explosion.

Environmental hazards

Most of the perchloroethylene released into the surrounding atmosphere is decomposed by sunlight to form products such as hydrogen chloride, trichloroacetic acid and carbon dioxide. Perchloroethylene in surface water evaporates rapidly and hardly degrades in water. The compound is stable in groundwater, which is the reason for the increased incidence of groundwater contamination due to industrial spills and waste accumulation.

First-aid

Skin Contact: Remove contaminated clothing and rinse skin thoroughly with soap and water.

Eye Contact: Lift the eyelids and flush with running water or normal saline. seek medical attention.

Inhalation: Quickly leave the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. seek medical attention.

Ingestion: Drink enough warm water to induce vomiting. seek medical attention.

Fire-fighting measures

Hazardous combustion products: hydrogen chloride, phosgene.

Fire fighting methods: Firefighters must wear oxygen breathing apparatus. Keep fire containers cool by spraying water until the fire is over.

Extinguishing media: water mist, foam, dry powder, carbon dioxide, sand.

Leak handling

Emergency treatment: quickly evacuate the personnel from the leaked contaminated area to a safe area, isolate them, and strictly restrict access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Enter the scene from upwind. Cut off sources of leaks as much as possible. Prevent flow into restricted spaces such as sewers and flood drains.

Small spills: Absorb or absorb with sand or other non-combustible materials. It can also be scrubbed with an emulsion made of a non-flammable dispersant, which is diluted and put into the waste water system.

Large spills: Construct dikes or dig pits for containment. Cover with foam to reduce vapor hazards. Transfer it to a tanker or a special collector with a pump, and recycle it or transport it to a waste disposal site for disposal.

Operational Matters

Closed operation and enhanced ventilation. Operators must undergo special training and strictly abide by operating procedures. It is recommended that operators wear self-priming filter respirators (half masks), chemical safety goggles, gas-penetrating respirators, and chemical-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapors from leaking into the workplace air. Avoid contact with alkalis, active metal powders, and alkali metals. When handling, it should be lightly loaded and unloaded to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.

Storage Matters

The warehouse is ventilated and dry at low temperature; it is stored separately from oxidants and food additives; stabilizers, such as hydroquinone, are required for storage.

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The packaging is required to be sealed and not in contact with the air. It should be stored separately from alkalis, active metal powders, alkali metals, and edible chemicals, and should not be mixed. Equipped with the appropriate variety and quantity of fire equipment. Storage areas should be equipped with emergency release equipment and suitable containment materials.

Precaution

Engineering control: closed operation, pay attention to ventilation. Be mechanized and automated as much as possible. Safety showers and eye wash facilities are provided.

Respiratory system protection: When escaping in the air, it is recommended to wear a self-priming filter gas mask (half mask) and chemical safety glasses.

Body protection: gas-penetrating protective clothing.

Hand Protection: Wear chemical resistant gloves

Other protection: Smoking, eating and drinking are strictly prohibited at the work site. Store poison-contaminated clothes separately and wash them for later use. Practice good hygiene.
