Abstract
L'invention concerne un procédé de préparation d'acides phosphoriques par voie humide par réaction d'au moins un phosphate naturel sur au moins un acide fort, tel que l'acide sulfurique de préférence, caractérisé en ce que ladite réaction est effectuée en présente de 50 à 500 g/t de phosphate consommé d'au moins un agent tensioactif non ionique obtenu par condensation de 2 à 30 molécules d'oxyde d'éthylène par molécule d'au moins un alcool gras ramifié.
