高氯酸碳酰肼类配合物的比热容研究

Specific Heat Capacities of Carbohydrazide Perchloric Acid Coordination Compounds

用差示扫描量热仪(DSC)研究了高氯酸碳酰肼类配合物的比热容。测定了在50～140℃温度区间高氯酸碳酰肼合钴(Ⅱ)的比热容,以及在50～200℃温度区间高氯酸碳酰肼合锰(Ⅱ)、高氯酸碳酰肼合锌(Ⅱ)、高氯酸碳酰肼合镍(Ⅱ)的比热容,回归出比热容随温度变化的方程式,R≥0.985,标准方差SD≤0.060。在50.1～131.2℃温度区间,高氯酸碳酰肼合锰、高氯酸碳酰肼合锌的比热容方程符合二次函数,在50.1～142.9℃高氯酸碳酰肼合镍的比热容方程符合四次函数,在其余温度范围高氯酸碳酰肼合锰、高氯酸碳酰肼合锌和高氯酸碳酰肼合镍的比热容方程符合三次函数;高氯酸碳酰肼合钴(Ⅱ)比热容方程符合三次函数。对高氯酸碳酰肼合钴和高氯酸碳酰肼合镍进行了热重和红外分析。热重图谱显示仅[Co(CHZ)3](ClO4)2在140℃时开始失重,而加热前后它们各自的红外图谱均不同。

The specific heat capacity of carbohydrazide perchloric acid energetic coordination compounds was studied by differential scanning calorimetry （DSC）. The specific heat capacity of [ Co（CHZ） 3 ] （ClO4）2 was mensurated at 50 - 140 ℃ and the specific heat capacity of [Mn（CHZ）3] （ClO4）2,[Zn（CHZ）3] （ClO）2 and [ Ni（CHZ）3 ] （ClO4）2 was mensurated at 50 -200℃. The equations of the specific heat capacity changing with the temperature arc fitted by the least square method, i. e. R ≥ 0.985, SD≤0. 060. The equations of the specific heat capacity of [ Mn （ CHZ ）3] （ ClO4）2 and [Zn （ CHZ ） 3 ] （ ClO4 ）2 are functions of second degree at 50.1 - 131.2℃ and that of [ Ni （CHZ） 3 ] （ ClO4 ） 2 is the function of four degree at 50.1 - 142.9℃ ,however that of[Mn（CHZ）3] （ClO4）2,[Zn（CHZ）3] （ClO4）2 and [Ni（CHZ）3] （ClO4）2 are functions of three degree at the other temperature,and that of [ Co（CHZ）3] （ClO4）2 is the function of three degree. [Co（CHZ）3] （ClO4）2 and [Ni（CHZ）3] （ClO4）2were analyzed by method of TG and FTIR. TG curves show that only [ Co（CHZ） 3 ] （ClO4）2 loses weight after 140℃. FTIR spetra of two samples heated are different from that of the originals.
