Procedure

In 100 parts of methanol containing 30 wt. % of water, 20 parts of sodium p-styrenesulfonate and 20 parts of ammonium sulfate were charged. The mixture was stirred at 65° C. for 30 minutes. After cooling to 30° C., the reaction mixture was filtered and the filtrate was condensed and dried to obtain 18.7 parts of ammonium p-styrenesulfonate. Analysis showed that only 0.14 wt. % of Na and 0.01 wt. % of SO4 were included in the product.
