摘要
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.
