In a process for preparing hemipotassium phosphate useful as an acidulant for beverages, an equimolar mixture of monopotassium phosphate and phosphoric acid is heated to a temperature above 100 ~C then cooled with vigorous agitation whereby the liquid loses its free water and crystallizes to a relatively dry crystalline mass. The hemipotassium phosphate provides a dry, flowable, crystalline product which can be transported and handled easily.

Dans un procédé de préparation de phosphate hémipotassique utile comme acidulant pour boissons, un mélange équimolaire de phosphate monopotassique et d'acide phosphorique est chauffé jusqu'à une température supérieure à 100 ·C, puis refroidi à l'aide d'une agitation vigoureuse par laquelle le liquide perd son eau libre et se cristallise pour donner une masse cristalline relativement sèche. Le phosphate hémipotassique donne un produit sec, fluide, cristallin pouvant être transporté et manipulé facilement.
