Product 1

HCID 6364608Maleic acid, disodium salt

Procedure

An aqueous sodium maleate solution was prepared by neutralizing maleic anhydride with an aqueous sodium hydroxide solution in a four-necked flask. The aqueous solution polymerization of this solution and an aqueous acrylic acid solution was effected in the presence of ammonium persulfate, hydrogen peroxide and sodium hydroxide at 100° C. for 6 h.
