氧化铜转化法制备氢氧化钡

Preparation of Barium Hydroxide by Transformation of Copper Oxide

以硫化钡为原料,在水溶液中与氧化铜反应,生成氢氧化钡。副产物硫化铜经氧化焙烧生成氧化铜,循环使用于下一次合成中。放出的二氧化硫经石灰乳吸收用来制备亚硫酸氢钙。

Abstract The barium hydroxide was produced by the reaction of raw material barium sulfide with the copper oxide in water. The byproduct copper sulfide was transformed into copper oxide by roasting,which was cyclically used in the next syn- thesis. The dissipated sulfur dioxide was absorbed by the lime cream and applied for preparation of the calcium hydrogen sulfite.
