【摘要】：以馬來(lái)酸酐和丙烯酸為聚合單體,以過(guò)硫酸銨為引發(fā)劑,聚合得到馬來(lái)酸酐-丙烯酸共聚物。引入烯丙基磺酸鈉將馬來(lái)酸酐-丙烯酸共聚物進(jìn)行改性,得到磺酸基馬來(lái)酸酐-丙烯酸共聚物,磺酸基的引入增強(qiáng)了共聚物螯合鈣離子的能力和對(duì)碳酸鈣的分散性能。研究結(jié)果表明,磺酸基馬來(lái)酸酐-丙烯酸共聚物可以作為吸附劑去除工業(yè)硼酸中的鈣離子,為碳化硼的制備提供了質(zhì)量保障。
[Abstract]:Using maleic anhydride and acrylic acid as polymerization monomer and ammonium persulfate as initiator, the maleic anhydride acrylic acid copolymer was polymerized, and the maleic anhydride acrylic acid copolymer was modified with sodium allyl sulfonate. The copolymers of maleic anhydride and acrylic acid were obtained. The addition of sulfonic groups enhanced the ability of the copolymers to chelate calcium ions and the dispersion of calcium carbonate. Sulfonic anhydride-acrylic acid copolymer can be used as adsorbent to remove calcium ion from industrial boric acid, which provides quality assurance for the preparation of boron carbide.
