Abstract

PURPOSE: To manufacture prismatic basic aluminum sulfate having novel properties by adding soluble sulfate to an aqueous soln. of basic Al salt at a specified adding rate and reacting them.
CONSTITUTION: An alkali soln. is added to a soln. of Al salt of a univalent anion so as to make the molar ratio of OH/Al in the mixed soln. 0.5W2.55. To the resulting soln. of basic Al salt represented by a general formula Al(OH)cXd (where X is the univalent anion, c+d=3, and 0.5≤c≤2.55) is added soluble sulfate so as to make the molar ratio of SO4/Al≥(3-c)/2 in a time corresponding to an adding rate at which the adding time T satisfies both of equations T≥-14c+28 and T≥1.50, and they are reacted at ≤50°C. Thus, prismatic basic aluminum sulfate represented by a general formula Al(OH)a(SO4)b.nH2O (where a+2b=3, 2.44≤a≤2.56, 0.22≤b≤0.28, and 0≤n≤10) is obtd.
