Common name bromoacetic acid, colorless crystal, easy to deliquesce, soluble in water, ethanol, ether, acetone, benzene, tetrahydrofuran. Used in organic synthesis.
Stability
1. Stability: stable.
2. Incompatible materials: strong oxidants, strong alkalis.
3. Conditions to avoid contact: light, heat.
4. Polymerization hazard: no polymerization.
5. Decomposition product: hydrogen bromide.
6. Easily deliquescence. It can carry out many chemical reactions similar to chloroacetic acid, and the reaction conditions are relatively mild. It is easily hydrolyzed to produce glycolic acid when it comes into contact with water or humid air.
7. It is combustible in case of open flames and high heat. Contact with strong oxidants can cause chemical reactions. It is corrosive to most metals when wet. Hazardous combustion products carbon monoxide, carbon dioxide, hydrogen bromide.
8. The bromine atom is easily replaced by thiosulfate. It irritates and corrodes the skin, eyes and mucous membranes, and is more toxic than chloroacetic acid.
Storage method
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The package is sealed. It should be stored separately from oxidants, alkalis, and edible chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with suitable materials to contain the leakage.
Apps
1. Bromoacetic acid is the raw material for preparing ω-bromo-2,4-dichloroacetophenone, the latter is the intermediate for preparing imazalil, propiconazole and other triazole fungicides.
2. Organic synthesis intermediates. Used in the production of pesticides and medicines. It can also produce its esters.
3. Used in organic synthesis.
4. The esters of this product can be used to prepare β-hydroxy carboxylic acid, α, β unsaturated carboxylic acid.
Notes
Health hazards
Invasion route: inhalation, ingestion, transdermal absorption.
Health hazards: The product can cause severe local reactions to mucous membranes, eyes and skin; it can cause eye and skin burns. Animal poisoning manifested as gastroenteritis, jaundice and muscle weakness. Pathological examination showed obvious degeneration of the heart, liver, kidney and muscle. [6]
First aid measures
Skin contact: Take off contaminated clothing immediately and rinse with plenty of running water for at least 15 minutes. Seek medical attention.
Eye contact: Lift the eyelid immediately, and rinse thoroughly with plenty of running water or normal saline for at least 15 minutes. 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: Rinse mouth with water, drink milk or egg white. Seek medical attention.
Protection measures
Respiratory protection: In high-concentration environments, gas masks should be worn. Wear self-contained breathing apparatus during emergency rescue or escape.
Eye protection: wear chemical safety glasses.
Protective clothing: wear work clothes (made of anti-corrosion materials).
Hand protection: wear rubber gloves.
Others: After work, take a shower and change clothes. Pay attention to personal hygiene.
Fire-fighting measures
Hazardous combustion products: carbon monoxide, carbon dioxide, hydrogen bromide.
Fire extinguishing method: use water spray, foam, carbon dioxide to extinguish the fire.
Extinguishing agent: water mist, alcohol-resistant foam, dry powder, sandy soil.
Leakage emergency response
Emergency treatment: Isolate the leaked contaminated area and restrict access. Cut off the fire source. It is recommended that emergency treatment personnel wear dust masks (full face masks) and wear acid and alkali-proof overalls. Do not directly touch the leakage.
A small amount of leakage: use a clean shovel to collect in a dry, clean, covered container. You can also sprinkle the floor with soda ash, then wash it with a lot of water, and put it into the waste water system after the washing water is diluted.
A large amount of leakage: collect and recycle or transport to waste disposal sites for disposal.
Operational disposal and storage
Operation precautions: airtight operation, local exhaust. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety glasses, acid and alkali-proof overalls, and rubber acid and alkali-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidants and alkalis. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and 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 package is sealed. It should be stored separately from oxidants, alkalis, and edible chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment.
