摘要
采用正交方法研究了不同反应条件对三氧化二锑纯度、产率的影响 ,求得了三氧化二锑提纯的最佳工艺条件为 :锑白 /盐酸mol比 :1/ 12 5 ;溶解温度 :10 5℃ ;盐酸浓度 7mol/ 1;水解温度 :40℃ ;水解时间 :40min ;氨解温度 :10 0℃ ;氨解时间 :6 0min。
Effects on purity and productivity of antimony trioxide at different conditions were studied by orthogonal design,and the best condition of purification of antimony trioxide was obtained.The molecular ratio of antimony trioxide to hydrochloric acid is 1/12.5;The dissolving temperature is 105℃;The concentration of hydrochloric acid is 7mol/1;The hydrolysis temperature is 40℃;The hydrolysis time is 40min;The aminolysis temperature is 100℃;The aminolysis time is 60min.
