Product 1

HCID 31392Calcium phenolsulfonate

Procedure

To 1000 g of 5% phenol sulfonic acid aqueous solution stirred at room temperature, 30 g of calcium hydroxide was added. The stirring was continued while measuring the pH value. At the time when the pH value reached 6, approximately, filtration was done by using a 0.4 μm glass filter to remove the insoluble components, so as to obtain a calcium phenolsulfonate aqueous solution.
