| toxicity | toxic and corrosive. Oral or inhalation poisoning. Strong reaction with water releases irritant and corrosive gases, which can cause serious irritation to eyes, mucous membranes, skin and respiratory system. Patients who inhale human vapor should be removed from the contaminated area and placed to rest and keep warm. The patient developed eye irritation, rinsed with water, and rinsed with water for skin contact. The operator must wear whole body acid-resistant protective equipment. For the treatment of the leakage, dry sand is mixed and sent to the open area, and the diluted sewage is gradually poured into the water and put into the wastewater system. |
| Use | is used as a catalyst for organic synthesis. Brominating agent. Analytical reagents, isomerization catalysts. Used in the rubber industry. used as thermal softener of rubber, organic synthesis isomerization catalyst, can be used for the production of lithium aluminum hydride used as analytical reagent, isomerization catalyst film production, short shelf life of this product used as analytical reagents, organic synthesis isomerization catalyst |
| production method | can be made by the method of metallic aluminum or aluminum compound. Aluminum was added to the reactor by metal aluminum method, and bromine was added to react to generate aluminum bromide, and aluminum tribromide was prepared by vacuum distillation. Aluminum hydroxide was added to the reactor by 2A1 3Br2 → 2AIBr3 aluminum hydroxide method, hydrobromic acid was added to dissolve and react to form aluminum bromide. Al(OH)3 3HBr → A1Br3 3H2O |

Aluminium bromide, anhydrous - Safety
Open Data Verified Data
- This product is corrosive. Packaging glass bottles, and then concentrated in the wood box liner, each bottle of 500g net weight. Store in a cool, dry, to avoid direct sunlight in the warehouse, not affected with moisture; And alkali, oxidant Isolation storage and transportation, this product can corrode packaging, not long storage. It is an acid corrosion product. GB 8.1 class 81058. UNN0.17250 IMDG CODE page 8100, Class 3. Fire-fighting personnel must wear full-body protective clothing; Use cement powder, dry sand, carbon dioxide fire retardants, not water.
- toxicity and protection: toxic and corrosive. Poisoning by mouth or inhalation, and water release a strong reaction of irritant and corrosive gases, can seriously stimulate the eyes, mucous membranes, skin and respiratory system. Patients who inhale vapor should be removed from the contaminated area, placed to rest and kept warm. The patient developed eye irritation, rinsed with water, and rinsed with water for skin contact. The operator must wear the whole body acid-resistant protective equipment, treat the leakage, mix it with dry sand, send it to the open area, and gradually pour the diluted sewage into the water in batches and put it into the wastewater system.
