Ethyl orthosilicate, (C2H5O)4Si, the ester of orthosilicic acid and ethyl alcohol, is a colorless liquid boiling at 165° C. It can be hydrolyzed to produce what is known as a hydrated silica sol or a sol of condensed silicic acid and ethyl alcohol; and under suitable conditions the hydrated silica sol or condensed silicic acid sol can be made to form a gel. It was decided to study the rates of the hydrolysis and gel formation.
We have thus two reactions to be studied: 1. Eteyl orthosilicate + water ► silicic acid or condensed silicic acid + ethyl alcohol. 2. ilicic acid ► condensed silicic acid ► gel.
