Abstract
The invention provides a process for purifying gallium alkoxides by decreasing the amount of impurity chlorine contained therein, gallium alkoxides which are useful as raw materials for the formation of dielectrics containing gallium oxide and as raw materials for the syntheses of compounds for photoelectronics. Gallium isopropoxide containing 0.98 weight percent of chlorine and potassium isopropoxide of 1.4 equivalents to the impurity chlorine are refluxed in toluene as a solvent for 5 hours, the solvent is distilled away, and the residue is simply distilled under vacuum to obtain gallium isopropoxide containing 0.022 weight percent of the chlorine in a 89% yield.
