Procedure

While 1000 g of a phenol sulfonic acid aqueous solution at a concentration of 5% was stirred at room temperature, calcium hydroxide was gradually added to reach a pH of about 6. The mixture was continuously stirred for a while. Then, this was filtered with 0.4 micrometer glass filter to obtain a calcium phenolsulfonate aqueous solution, which was then spray-dried to obtain powders of calcium phenolsulfonate.
