Procedure

In another 1-liter flask, 297 grams 2-propanol, 148.560 grams acetone, 139.902 grams TEOS, 19.10 grams MTEOS, 51.7 g PTEOS, 5.624 grams 0.1 M nitric acid and 66.827 grams deionized water were combined. The flask was refluxed and/or heated for 1 to 12 hours. To the solution, 43.93 grams of butanol was added. The solution was filtered to be used in the pH tuning experiments.
