What is a carboxylate salt and how are they formed?
Because of their enhanced acidity, carboxylic acids react with bases to form ionic salts, as shown in the following equations.
In the case of alkali metal hydroxides and simple amines (or ammonia) the resulting salts have pronounced ionic character and are usually soluble in water.The sodium salt of a carboxylic acid (A) was produced by passing a gas (B) into an aqueous solution of caustic alkali at an envolved temperature and pressure (A) on heating in the presence of sodium hydroxide followed by the treatment with sulphuric acid gave a dibasic acid (C).
How do you make carboxylate salt?
A carboxylic acid salt is prepared by contacting a compound containing at least one primary alcohol group with a platinum containing catalyst at elevated temperature in an aqueous solution, containing at least one alkali metal and/or alkaline earth metal hydroxide.
What is ammonium salt of carboxylic acid?
The carboxylic acid is first converted into an ammonium salt which then produces an amide on heating.
The ammonium salt is formed by adding solid ammonium carbonate to an excess of the acid.
For example, ammonium ethanoate is made by adding ammonium carbonate to an excess of ethanoic acid.
