Abstract
The present invention is a method of producing dry, alkali metal or ammonium carboxylic acid salt particles. In accordance with the invention, a molten carboxylic acid is mixed with a solution of an alkali metal-containing or ammonium-containing alkaline compound and the carboxylic acid and alkaline compound are reacted to form the carboxylic acid salt. Water is then removed from the carboxylic acid salt to produce dry, carboxylic acid salt particles. The feed ratio of the molten carboxylic acid and the alkaline compound is controlled to neutralize the carboxylic acid in the process.
