摘　　要：以探究过氧化氢的稳定性为目的,采用氯酸钠为母体,以过氧化氢为还原剂,研究了几种稳定剂来降低过氧化氢的分解,通过稳定剂HEDP与几种复合稳定剂相比较,确定最佳稳定剂为复合稳定剂A(硫酸镁∶硅酸钠∶HEDP=7∶5∶1),其最佳用量为反应物料中过氧化氢质量分数的2.5%,能有效的对过氧化氢起到稳定的效果,进而提高二氧化氯的收率和其纯度,从而为其工业化生产奠定基础。To explore the stability of hydrogen peroxide,using sodium chlorate as the matrix and hydrogen peroxide as the reducing agent,several kinds of stabilizer was studied to reduce the decomposition of hydrogen peroxide by stabilizing agent HEDP compared with several kinds of composite stabilizer,determine the optimal stabilizer for A composite stabilizer(magnesium sulfate∶sodium silicate∶HEDP=7∶5∶1),the best dosage of 2.5%of hydrogen peroxide mass fraction of reaction materials,can effectively have the stable effect of hydrogen peroxide,thus improving the yield of chlorine dioxide and its purity,and thus lay the foundation for its industrial production.
