Triisobutyl Aluminium - Nature
Open Data Verified Data
A colorless transparent liquid with a strong smell of mildew. The chemical properties are more active, and the chemical reaction activity is high. Soluble in benzene. Contact with air will smoke spontaneous combustion, suppress water, acid, alcohol, ammonia will occur hydrolysis, alcoholysis, acid hydrolysis and other reactions, while releasing a lot of heat and isobutane, an explosion can also occur when the reaction is severe.

Triisobutyl Aluminium - Safety
Open Data Verified Data
It is highly irritating and corrosive, causing damage to the respiratory tract and the conjunctiva. The maximum allowable concentration of hazardous substances in the air of the workshop is 2mg/m3[ Al].; Comprehensive protection should be taken. If inhalation or contact with the skin is accidental, a large amount of flowing water or normal saline should be used to rinse thoroughly and seek medical treatment. In the production process, sampling analysis or leakage, easy to cause combustion explosion, should pay more attention. Mixing with oxidants, acids, alcohols and edible chemicals is strictly prohibited. Storage and transport must be filled with inert gas or a specific container. Keep away from fire and heat source. The bin temperature should not exceed 30 ℃. The relative humidity was maintained below 75%.
