稳定性

常温常压下稳定

避免的物料 氧化物。因在空气中易于氧化,故过滤等操作应在隔绝空气下进行。对于盐酸或硫酸等如在无空气条件下,也不能溶解。如接触空气时,则被氧化生成高铼酸而溶解。接触氧化剂(如Br2、H2O2等)也是如此,能吸附甲苯等而膨润。

水溶解性 insoluble H2O; soluble alkali sulfide solutions [HAW93]

1.于20~80℃下往Re2O7中通入硫化氢。

2.取过量的硫化钠加到高铼酸钾水溶液中,再加入浓盐酸及硫酸铵,配制成约6mol/L盐酸酸性混合液后,煮沸之,Re2S7则沉淀出来,将该溶液冷却至室温,过滤,洗涤后进行真空干燥。

3.取1g市售的高铼酸钾粉碎后,溶于100mL左右热稀盐酸(10%)中,往该溶液中通入硫化氢,则七硫化二铼以细粉状黑色沉淀析出,沉淀凝聚后,在隔绝空气下,过滤,先用硫化氢水溶液洗涤,接着用水洗涤,将沉淀先在真空中于140℃下加热2h,接着在P2O5上于165~170℃下干燥(以Abdelhalden干燥器为宜)。
