Stannous hydroxide

中文百科

氢氧化亚锡 Tin(II) hydroxide

(重定向自Stannous hydroxide)

氢氧化亚锡是一种不存在的无机化合物,实际上是水合氧化亚锡,只是为了表达方便,化学式写作Sn(OH)2并成为氢氧化亚锡。氢氧化亚锡是锡的2价(氧化态)化合物。氢氧化亚锡的外观是白色结晶粉末,有时会呈或微黄色结晶粉末,熔点约为摄氏120,难溶于水,微溶乙醇、乙醚,易溶于二氯烃类、丙酮等有机化合物、遇到高温容易分解或脱水变成黑色的一氧化锡。

氢氧化亚锡置于空气中常常会被氢氧化成氢氧化锡。

Tin(II) hydroxide 氢氧化亚锡

(重定向自Stannous hydroxide)

Tin(II) hydroxide, Sn(OH)2, also known as stannous hydroxide, is a chemical compound of tin in the +2 oxidation state. Pure Sn(OH)2 is prepared by reacting for example (CH3)3SnOH with SnCl2 in an aprotic solvent:

There had been confusion as it had been believed that Sn(OH)2 was precipitated when a tin(II) salt is reacted with an alkali hydroxide such as NaOH, but this product was determined analytically to be hydrated tin(II) oxide, being either 5 SnO • 2 H2O or 3 SnO • H2O. The structure of pure Sn(OH)2 is not known.
