A method for producing a particulate aluminum alloy involves pulverizing an aluminum alloy in a hydrocarbon solvent in the presence of an organic aluminum compound. Methods for producing trialkylaluminum involve reacting an aluminum-magnesium alloy with an alkyl halide in the presence of a nitrogen-containing organic compound to obtain a trialkylaluminum-containing reaction product, and reacting an aluminum-magnesium alloy and an alkyl halide. A highly active, low viscosity composition containing the particulate aluminum alloy and a method for producing the particulate aluminum alloy-containing composition are also described.
A composition comprising a particulate aluminum alloy having a median diameter equal to or less than 50 μm, a hydrocarbon solvent, and an organoaluminum compound represented by general formula (1) below.
A method for producing a particulate aluminum alloy, comprising pulverizing a slurry that contains an aluminum alloy, a hydrocarbon solvent, and an organoaluminum compound represented by the following general formula (1) to prepare a slurry containing a particulate aluminum alloy, and recovering the particulate aluminum alloy from the prepared slurry.
A method for producing trialkylaluminum, comprising a step (1) of obtaining a trialkylaluminum-containing reaction product by reacting an aluminum-magnesium alloy with an alkyl halide in the presence of a nitrogen-containing organic compound.

The present invention relates to a particulate aluminum alloy and to a composition that contains the particulate alloy. The present invention further relates to a method for producing the particulate alloy-containing composition and to a method for producing trialkylaluminum using the particulate alloy-containing composition.
The trialkylaluminums produced by the above production method are strong Lewis acids and are useful compounds used for catalysts for organic synthesis and cocatalysts for polyolefin synthesis as well as for starting materials for same. They are also used as starting materials for semiconductors for, e.g., light-emitting devices and solar cells.
The present application cites priority to Japanese Patent Application No. 2016-205712 filed Oct. 20, 2016 and Japanese Patent Application No. 2017-030968 filed Feb. 22, 2017, the entire contents of which are specifically cited as references herein.
An embodiment (the first embodiment) for executing the first aspect of the invention is described in the following.
The production method according to the present embodiment contains a step of pulverizing a slurry that contains an aluminum alloy, a hydrocarbon solvent, and an organoaluminum compound represented by general formula (1).
(In the formula, R1, R2, and R3 each independently represent a hydrogen atom, a linear or branched alkyl group having 1 to 6 carbons, an aryl group, or a halogen atom.)
