摘要： A contaminated Group III metal hydrocarbon is purified by providing an adduct of Group III metal hydrocarbon with a Lewis base in a solvent having a boiling point which is up to 200 DEG C, but at least 30 DEG C higher than the boiling point of the Group III metal hydrocarbon, separating the solvent from the adduct, and heating the adduct for thermal dissociation, thereby releasing the Group III metal hydrocarbon in high purity form.

摘要： Trialkylgallium is prepared by reacting a gallium halide or alkyl gallium with trialkylaluminum in a solvent having a boiling point which is at least 10 DEG C higher than the boiling point of the trialkylgallium, such as mesitylene or o-dichlorobenzene. High purity alkyl gallium is obtained in high yields.

摘要： PROBLEM TO BE SOLVED: To provide a method for industrially and inexpensively producing an organometallic compound. SOLUTION: In the method for producing the organometallic compound, it is repeated that a trialkylaluminum is reacted with a metal halide to provide the organometallic compound and the trialkylaluminum is regenerated from the reaction products containing a dialkylaluminum halide which is the above by-product and the regenerated trialkylaluminum is again reacted with the metal halide to provide the organometallic compound.
