    Allyl chloride

    Update time:2021/11/05 13:44:11  ???View:  
    Allyl chloride is a colorless transparent liquid with an unpleasant irritating odor. It is slightly soluble in water and easily soluble in most organic solvents such as ethanol, ether, chloroform and petroleum ether. It is mainly used for medicines, pesticides, plastics, etc. Intermediate. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 29℃. The packaging is required to be sealed and not in contact with air.
    Environmental characteristics
    Hazardous characteristics: its vapor and air can form an explosive mixture. In case of open flames, high heat or contact with oxidants, there is a danger of burning and explosion. Reacts violently with nitric acid, fuming sulfuric acid, chlorosulfonic acid, ethylene imine, ethylene diamine, and sodium hydroxide. Under the high temperature of the fire site, polymerization exotherm can occur, causing the container to rupture. When encountering acidic catalysts such as Lewis catalysts, Ziegler catalysts, sulfuric acid, ferric chloride, aluminum chloride, etc., it can polymerize violently and release a lot of heat. Its vapor is heavier than air and can spread to a considerable distance in a lower place, and it will cause back-combustion when it encounters an open flame.
    Combustion (decomposition) products: carbon monoxide, carbon dioxide, hydrogen chloride.
    Storage method
    Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 29℃. The packaging is required to be sealed and not in contact with air. It should be stored separately from oxidants, acids and alkalis, and avoid mixed storage. Do not store in large quantities or for long periods of time. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials.
    Use
    1. It is an organic synthetic raw material, used in pesticides to synthesize N,N-dimethyl allylamine and pyrethroid intermediates propenol ketone, as well as special The solvent of the reaction.
    2. It has the reactivity of olefins and halogenated hydrocarbons, and is an organic synthesis intermediate for glycerol, epichlorohydrin, allyl alcohol, etc. It is also used as a raw material for pesticides and medicines. It can also be used as a raw material for fine chemicals such as synthetic resins, coatings, binders, plasticizers, stabilizers, surfactants, lubricants, soil conditioners, perfumes, etc. It is mainly used to produce epichlorohydrin, glycerin, Chloropropanol, allyl alcohol, pesticide insecticide, medicines, resins, coatings, adhesives, as well as sodium propylene sulfonate, lubricants, etc.
    3. Used in organic synthesis and pharmaceutical industry. It is also used in the preparation of intermediates such as plastics.
    4. Used as intermediates for medicines, pesticides, plastics, etc.
    Protection measures
    Respiratory protection: When the concentration in the air exceeds the standard, wear a self-priming filter gas mask (half mask).
    Eye protection: wear chemical safety glasses.
    Body protection: wear anti-static overalls.
    Hand protection: wear rubber gloves.
    Others: Smoking, eating and drinking are prohibited at the work site. After work, take a shower and change clothes. Pay attention to personal hygiene.
    First aid measures
    Skin contact: Take off contaminated clothing and wash skin thoroughly with soap and water.
    Eye contact: Lift the eyelid and rinse with running water or normal saline. Seek medical attention.
    Inhalation: quickly leave the scene to a place with fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
    Ingestion: Drink enough warm water, induce vomiting, and seek medical attention.
    Fire fighting method: Move the container from the fire scene to an open place as much as possible. Spray water to cool the fire container until the end of the fire. If the container in the fire scene has changed color or produces sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: foam, dry powder, carbon dioxide, sandy soil. Extinguishing with water is ineffective.
    Leak handling
    Quickly evacuate personnel from the contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protective clothing. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and flood drains. Small leakage: Use activated carbon or other inert materials to absorb. It can also be scrubbed with an emulsion made of a non-flammable dispersant, and the lotion is diluted and put into the waste water system. A large number of leaks: construct dikes or dig pits for storage; cover with foam to reduce steam disasters. Use explosion-proof pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.
    Waste disposal method: use incineration.
