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 alkyline compound is controlled to neutralize the carboxylic acid in the process.
L'invention concerne un procédé de production de particules sèches de sel d'acide alcalinométallique ou ammonium. Selon la présente invention, un acide carboxylique en fusion est mélangé à une solution d'un composant alcalin contenant de l'ammonium ou un métal alcalin et l'acide carboxylique et un composant alcalin réagissent afin de former le sel d'acide carboxylique. On retire alors l'eau du sel d'acide carboxylique afin de produire des particules de sel d'acide carboxylique sèches. Le taux d'alimentation de l'acide carboxylique en fusion et le composant alcalin est contrôlé afin de neutraliser l'acide carboxylique dans le procédé.
