Abstract

Afin de contrecarrer la tendance à se dissocier d'un détergent de faible alcalinité pour lave-vaisselle, on met en oeuvre un procédé de préparation de produits granulés précurseurs de ces détergents qui contiennent des sels de métaux alcalins de l'acide carboxylique et des acides polycarboxyliques organiques. A cet effet, on produit une partie des sels des acides polycarboxyliques de la manière usuelle, puis on fait réagir le carbonate alcalin avec les acides polycarboxyliques libres et leurs sels, ainsi que l'hydrocarbonate alcalin, en présence de 2 à 12 % en poids d'eau et des sels de métaux alcalins des acides polycarboxyliques à des températures inférieures à 60 °C.
