When exposed to air under light, it is gradually oxidized to form highly toxic phosgene, so it needs to be stored in a sealed brown bottle. Often 1% ethanol is added to destroy the phosgene that may be formed. It is not easy to burn, and can be oxidized into hydrogen chloride and highly toxic phosgene by oxygen in the air under the action of light. It is most easily hydrolyzed into formic acid and HCl in methyl chloride, with poor stability, thermal decomposition occurs above 450 ℃, and it can be further chlorinated to CCl4.


Organic synthesis raw materials, mainly used to produce Freon (F-21, F-22, F-23), dyes and drugs, in medicine, commonly used as anesthetics. It can be used as a solvent and extractant for antibiotics, spices, oils, resins, and rubber. It can be mixed with carbon tetrachloride to make a non-freezing fireproof liquid. Also used as propellant for aerosols, fumigants for grains and standard solutions for temperature calibration. Industrial products are usually added with a small amount of ethanol, so that the generated phosgene reacts with ethanol to form non-toxic diethyl carbonate. Before using the industrial product, a small amount of concentrated sulfuric acid can be added, shaken, washed with water, and dried with calcium chloride or potassium carbonate to obtain ethanol-free chloroform.


Use precautions

Hazard overview

Health Hazards: Mainly acts on the central nervous system, has anesthesia effect, and damages the heart, liver and kidneys. Acute poisoning: Acute poisoning by inhalation or skin absorption. The initial symptoms include headache, dizziness, nausea, vomiting, excitement, skin heat and mucous membrane irritation. Later, mental disorders, superficial breathing, loss of reflexes, coma, etc. will occur, and in severe cases, respiratory paralysis and ventricular fibrillation will occur. At the same time can be accompanied by liver and kidney damage. When poisoned by mistake, the stomach has a burning sensation, accompanied by nausea, vomiting, abdominal pain, diarrhea. Symptoms of anesthesia occur later. Liquid can cause dermatitis, eczema, and even skin burns. Chronic effects: mainly cause liver damage, and have indigestion, fatigue, headache, insomnia and other symptoms, a few have kidney damage and chloroform addiction.

Environmental Hazards: Harmful to the environment and can cause pollution to water bodies.

Explosion hazard: This product is non-flammable, toxic, suspected carcinogen and irritant. 


Skin Contact: Immediately remove contaminated clothing and rinse with plenty of running water for at least 15 minutes. seek medical attention.

Eye Contact: Immediately lift eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. 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 properties: Can produce highly toxic phosgene when in contact with open flames or hot objects. Under the action of air, moisture and light, the acidity increases, so it is strongly corrosive to metals.

Hazardous combustion products: hydrogen chloride, phosgene.

Fire fighting methods: Firefighters must wear filter respirators (full face masks) or isolation respirators, wear full-body fireproof and anti-gas suits, and put out the fire in the upwind direction.

Extinguishing media: water mist, carbon dioxide, sand. [2] 

Emergency release treatment

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. Do not come into direct contact with spillage. Cut off sources of leaks as much as possible.

Small spills: Absorb with sand, vermiculite or other inert material.

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. 

Handling and Storage

Operation precautions: closed operation, local exhaust. Operators must undergo special training and strictly abide by operating procedures. It is recommended that operators wear direct gas masks (half masks), chemical safety goggles, anti-gas permeable work clothes, and chemical-resistant gloves. Prevent vapors from leaking into the workplace air. Avoid contact with alkalis and aluminum. When handling, it should be lightly loaded and unloaded to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.

Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃, and the relative humidity should not exceed 80%. Keep container tightly closed. It should be stored separately from alkalis, aluminum, and edible chemicals, and should not be mixed. Storage areas should be equipped with emergency release equipment and suitable containment materials.
