制备方法与用途

工业上生产硫化钠的主要方法有以下几种：

1. 煤粉还原法：将芒硝与煤粉按比例混合后高温煅烧还原，生成的产物用碱液溶解并浓缩，制得固体硫化钠。
2. 吸收法：使用氢氧化钠溶液吸收含有高浓度H2S的废气，反应生成硫化钠。这种方法适用于废气处理的同时生产硫化钠。
3. 硫化钡法：利用硫酸钠与硫化钡进行复分解反应制备沉淀硫酸钡时副产硫化钠。
4. 气体还原法：在有铁催化剂的情况下，将氢气、一氧化碳或甲烷等气体与硫酸钠反应生成无水颗粒状的硫化钠。

近年来，行业内更倾向于采用精制法和煤粉还原芒硝法。其中：

• 精制法以沉淀硫酸钡过程中副产的低浓度硫化钠溶液为原料，通过蒸发浓缩、除铁除碳等步骤最终得到高纯度硫化钠。
• 煤粉还原芒硝法则是在传统生产工艺基础上进行改进，提高了产品质量和设备耐腐蚀性。

此外，还有气体还原法直接制备高纯度无水颗粒状硫化钠。每种方法都有其特点和技术要求，在实际生产中可根据具体情况选择合适的方法。

  作者：Vivian Wing-Wah Yam、Kenneth Kam-Wing Lo、Chun-Ru Wang、Kung-Kai Cheung

  DOI：10.1021/jp9639051

  日期：1997.6.1

  A luminescent copper(I) sulfide cluster [Cu-4(mu-dtpm)(4)(mu(4)-S)](PF6)(2) (3) dtpm = bis[bis(4-methylphenyl)-phosphino]methane} has been synthesized and characterized by X-ray crystallography. Its photophysical and electrochemical properties have also been studied. The long-lived photoluminescence of 3 is assigned to originate from an excited state with a parentage of large ligand-to-metal charge-transfer LMCT [(S2-) --> Cu-4] character, with mixing of metal-centered MC [(ds/dp) Cu(I)(4)] state, The phosphorescent state of 3, as well as those of its analogues [Cu-4(mu-dppm)(4)(mu(4)-S)](PF6)(2) (1) and [Cu-4(mu-dppm)(4)(mu(4)-Se)](PF6)(2) (2), have been found to undergo facile electron-transfer reactions with different pyridinium accepters, which have been investigated with nanosecond transient absorption spectroscopy. Crystal data for 3: a = 37.38(1) Angstrom, b = 15.905(7) Angstrom, c = 27.761(5) Angstrom, beta = 128.69(1)degrees, V = 12881(6) Angstrom(3), Z = 4.
