We report an optimized synthesis of aluminum n-hexyloxide (AH), aluminum phenoxide (APh) and aluminum isopropoxide (AIP) with high yields. Aluminum alkoxides, among other applications, are important starting materials to produce high surface area alumina catalyst supports for catalytic applications, such as hydrocracking and supported Fischer-Tropsch catalysts (FT). One mole of aluminum was reacted with excess alcohol in the presence of 0.001 mole mercuric chloride catalyst. All solid alkoxides were obtained in high yields (90-95%) and analyzed by H-1 NMR, C-13 NMR and Al-27 NMR, X-ray diffraction (XRD), ICP-MS and elemental analysis. Aluminum n-hexyloxide was synthesized and characterized for the first time. Results indicate that fresh AH, APh, and ALP have the same coordination number of aluminum, but AIP changes as it ages.
