[0002] Three isobutyl aluminum, an organic compound, has a chemical formula of C8H 18 AlF, a colorless transparent liquid, is mainly used as a polymerization catalyst for butadiene rubber, synthetic resin, synthetic fiber and olefin polymer. It has a strong moldy odor, high chemical activity and high reactivity. It is highly corrosive and irritating, and can self-ignite when exposed to air. It will undergo hydrolysis, alcoholysis, acidolysis, etc. when it comes into contact with water, alcohol, acid, ammonia, etc., while releasing a large amount of heat and isobutane. The reaction is violent and can easily cause combustion and explosion. Therefore, the disposal of waste three isobutyl aluminum is difficult and dangerous. The existing technology involves similar methods for disposing of waste alkyl aluminum, such as adding triethyl aluminum deactivator to the waste liquid, making it inactive, and then using nitrogen to press it into a storage tank, and then sending it to a special waste fluidized bed combustion furnace for further treatment. This method requires the addition of a large amount of deactivator, which increases the cost of treatment, and the waste triethyl aluminum needs to be transferred to a secondary tank, which can easily cause accidents during the process.
