Procedure

The sodium octoate was prepared by stirring 3.60 g of octanoic acid in 3 g of water and neutralizing with 2.00 g of aqueous sodium hydroxide (50%). 5 g of water was used for dilution and rinse. A waxy solid formed which was dissolved by adding about 10 ml of ethanol. pH paper indicated a pH of about 8. The total solution was evaporated on a watch glass on a steam bath under a flow of nitrogen to give 4.04 g white solid. The solid was titrated in ethanol with aqueous HCl: the titer was 5.88 mmol/g. Estimated purity was 97.6%.
