    Abstract: PURPOSE:To obtain an amorphous aluminosilicate having high oil-absorptivity and ion-exchange capacity, by adding an aqueous solution of a specific alkali metal aluminate to an aqueous solution of an alkali metal silicate and treating the mixture under specific condition. CONSTITUTION:An alkali metal aluminate having low alkali content and having an M2O/Al2O3 molar ratio of 1-2 and H2O/M2O ratio of 6-500 is prepared beforehand. Separately, an alkali metal silicate having an SiO2/M2O molar ratio of 1-4 and H2O/M2O ratio of 12-200 is prepared. The aqueous solution of the above alkali metal aluminate is added to an aqueous solution of the alkali metal silicate at 15-100 deg.C under vigorous agitation. The mixture is heated at 70-100 deg.C to obtain the objective amorphous aluminosilicate.

    Abstract: PURPOSE:To obtain a pigment which has excellent resistance to water, solvents, oxidation and light and safety and gives a clear color, by bringing a porous alumina contg. an anion into contact with an org. dye soln. and then sealing pores. CONSTITUTION:A porous alumina contg. 0.1mol/kg or more of an anion is brought into contact with an org. dye soln. to enclose a dye in pores, and the pores contg. the dye are sealed. Any of porous alumina contg. 0.1mol/kg or more of an anion and having pores capable of enclosing an org. dye molecule therein may be used, but one having a specific surface area of 10m /g or above is preferred to enclose the dye molecule therein. As the anion, chloride and sulfate ions are particularly preferred.

    Abstract: PURPOSE: To improve the yield of manufacture by bringing magnesium oxide having a specified specific surface area into contact with mother liquor for crystallizing sodium percarbonate at a specified temp. to inhibit the decomposition of H
    2 O
    2 in the mother liquor.
    CONSTITUTION: Sodium percarbonate crystals are deposited from an H
    2 O
    2 soln. and an Na
    2 CO
    3 soln. Mother liquor consisting of the solns. for crystallizing sodium percarbonate is treated by bringing magnesium oxide having ≥1m
    2 /g specific surface area, preferably highly active magnesium oxide having 50W 200m
    2 /g specific surface area into contact with the mother liquor at ≤28°C, preferably ≤25°C. In case of bath treatment, the amount of magnesium oxide to be used is about 0.1W10wt% of the amount of the mother liquor, and the contact time is about 1minW2hr. In case of column treatment, about 10W5,000 times as much mother liquor as magnesium oxide is passed at ≥2 superficial linear velocity in column. The decomposition of H
    2 O
    2 in the mother liquor is inhibited, and the stability of sodium percarbonate is improved.
