硫酸亚锡制备

1制法
硫酸亚锡的制造方法有以下五种,其中主要制备方法是合成法。
(1)氧化亚锡  硫酸合成法 将氯化亚锡溶于盐酸,加水稀释,在不断搅拌下缓缓加入浓度为10%~15%经过滤的碳酸钠溶液,至溶液呈碱性为止,生成氧化亚锡沉淀。加热反应器中之悬浮液,至白色沉淀完全转变为黑色有光泽的沉淀。冷却后过滤,并用水漂洗至无氯离子反应。在溶解器中加热,使黑色沉淀溶于10%~15%的硫酸中,将黄色不溶物滤去,然后蒸发浓缩,并及时过滤生成的硫酸亚锡结晶,滤液弃去,滤饼用乙醇洗涤,再经低温干燥即为成品。乙醇洗液可回收利用。其反应式如下:

(2)萃取法 将粒状锡与过量稀硫酸在100℃以上作用,然后用水萃取,在真空中蒸发结晶而得。

(3)沉淀法 将氯化亚锡溶液加硫酸沉淀而得。
(4)混酸法 用浓硫酸、浓硝酸与水的混合物溶解锡片而制得。
(5)置换法 硫酸铜与锡置换反应制得。
