摘要
用量热滴定法研究2,4-二氯酚与吡啶的氢键络合反应李志伟,陈爱通,胡日恒(天津大学化学系,天津,300072)(中国科学院化学研究所)关键词2,4-二氯酚,吡啶,正庚烷,氢键,量热滴定利用反应热测定样品滴定度是一种新兴的方法。在反应常数为103~10...
The authors have investigated the titled complex react ion. The result is in agreement with that of the infrared spectroscopy work. The reaction enthalpy △H=-21.0±0. 2 kJ/mol,the equilibrium constant k=31±3 L/mol(at 20. 0℃ and normal pressure). In addition, the authors have discussed the experiment design and given a new data processing methed for this sort of experiments.
