摘　　要：采用热失重分析法（ＴＧ）、差示扫描量热法（ＤＳＣ）、红外分析法（ＦＴ－ＩＲ）和核磁共振法（ＮＭＲ）对三环己基氢氧化锡热变化进行了详细研究。在ＴＧＡ曲线上，三环己基氢氧化锡热失重Ｔｏｎｓｅｔ＝１２６．１℃，△Ｗ＝２．３２％，在ＤＳＣ曲线上为吸热转变Ｔｏｎｓｅｔ＝９４．１℃，Ｔｐｅａｋ＝１２４．１℃，△Ｈ１１１．５５Ｊ／ｇ（４２．９６ＫＪ／ｍｏｌ）。通过热分析数据，红外，核磁综合分析，确认此过程为脱水反应。三环己基氢氧化锡受热脱水，生成六环己基二锡氧化物。A thorough study has been made of the behavior of thermal reaction of tricyclohexyltin hydroxide (stannane tricyclohexylhydroxy - [1312] - 70 - 5]). It had an endothermic transition at in DSC curve and had a weight loss at in TGA curve. It was concluded from thermal analysis data and FT-IR that dehydration would take place when tricyclohexyltin hydroxide was heated (80 -150℃ ) and thus distannoane hexacyclohexyl -would be formed.
