Hydrochloric Acid → 1-Pentanol

First, 24.6 g of aluminum sec-butoxide (ASBD, manufactured by Kawaken Fine Chemicals Co., Ltd.), 6.51 g of 3-oxobutanoic acid ethyl ester, and 1-pentanol were mixed. The mixture displayed a white turbidity at first and stirred to form uniform solution. After 0.01 M dilute hydrochloric acid was dissolved in a 1-pentanol/1-ethoxy-2-propanol mixed solvent, the resulting solution was slowly added to the aluminum sec-butoxide solution. The mixture was stirred for some time. The solvent was adjusted to finally obtain the mixed solvent of 49 g of 1-pentanol and 21 g of 1-ethoxy-2-propanol. The mixture was further stirred in an oil bath with a temperature of 120° C. for 2 to 3 hours or more, thereby preparing a precursor sol of aluminum oxide. Thereby, precursor sols 8 to 11 of aluminum oxide were prepared, the sols containing different amounts, i.e., 1.8 g, 2.25 g, 2.7 g, and 3.06 g, of 0.01 M dilute hydrochloric acid.
