PROCESS FOR MAKING AQUEOUS ALKALI METAL PHOSPHATE SOLUTIONS ABSTRACT OF THE DISCLOSURE: The invention relates to a process for making aqueous alkali metal phosphate solutions by subjecting aqueous alkali metal phosphite solutions to catalytic oxidation with oxygen or air. More particularly, oxygen or air in stoichiometric excess proportions is introduced into the aqueous alkali. metal phosphite solution at about 30 to 110°C at a pH-value of 0 to about 8, and in the presence of SiO2 or aluminium silicate containing at most 10 weight % Al2O3, for as long as necessary to achieve conversion of the alkali metal phosphite to alkali metal phosphate. After completion of the oxidation, the aqueous solution is separated from the catalyst.
