摘要
用自行研制的具有恒定温度环境的新型反应热量计，以０．０１ｍｏｌ·Ｌ－１Ｈ２ＳＯ４溶液为量热溶剂，分别测定了［２ＣｓＣｌ（ｓ）＋ＣｕＣｌ·２Ｈ２Ｏ（ｓ）］和Ｃｓ２ＣｕＣｌ４的溶解焓，根据Ｈｃｓｓ定律设计了一个热化学循环，求出了Ｃｓ２ＣｕＣｌ４的标准生成焓，推荐其值为：ΔｆＨ（Ｃｓ２ＣｕＣｌ４，Ｓ，２９８．２Ｋ）＝－１１２９．０４ｋＪ·ｍｏｌ－１．
he standard enthalpy of formation of Cs2CuCl4 was determined by a new model isoperibel reaction calorimeter. The calorimetric solvent is an acid solution consisting of 0.01mol L-1 H2SO4 A thermochemical cycle was designed to determine the enthalpy. According to the results obtained, the value ΔfH(Cs2CuCl4, s, 298.2K)=-1129.04kJ·mol-1 was recommended.
