测定了双硫脲金(Ⅰ)配合物(Cl-)的红外光谱、差热曲线(DTA)、热重曲线(TG);测定在21个不同温度下配合物发生分解反应后产物的红外谱图;提出了配合物热分解机理的一些论断;估算了热分解反应的活化能和指前因子;查明了双硫脲金(Ⅰ)配合物在升温速度为10℃/min条件下在230—260℃温度范围内配位体中硫脲能发生同分异构转变,硫脲转变为异硫氰酸铵;分解反应从～240℃开始,～322℃结束,650℃以上Au_2S分解为金属金。
The infrared spectrum, DTA and TG of bis (dithio) gold (Ⅰ) complex (Cl-) were measured. The infrared spectrum of the product after the decomposition reaction was measured at 21 different temperatures Some conclusions about the mechanism of the thermal decomposition of the complex were proposed. The activation energy and the pre-exponential factor of the thermal decomposition reaction were estimated. The results showed that the complex of gold (Ⅰ) Thiourea can undergo isomerization transformation in the ligand at temperature range of -260 ℃ and thiourea to ammonium isothiocyanate. The decomposition reaction begins at ~ 240 ℃, ends at ~ 322 ℃, and Au_2S decomposes to metal at 650 ℃ gold.
