| Abstract: | A procedure for the semimicrodetermination of carboxylic acids in the presence of a large excess of acyl chloride is described. Acyl chloride is first reacted with m-chloroaniline. The m-chloroaniline hydrochloride and carboxylic acid are then determined sequentially by potentiometric titration with sodium hydroxide. Titrations are performed in 80–90% p-dioxane to enhance the potentiometric breaks. With 0.05 N sodium hydroxide, as little as 0.01 mM of carboxylic acid can be determined. |
