斯蒂芬酸在DMF中的热化学和热动力学性质研究
Thermochemistry and Thermodynamics of Solution of Styphnic Acid in DMF at 298.15 K
摘要
Abstract
The enthalpies of solution and the thermodynamics of styphnic acid 2,4,6-trinitroresorcinol (TNR) the solution solved in DMF were studied.The enthalpies of TNR solution with different concentrations were measured by a SETARAM C80Ⅱcalorimeter at 298.15 K and the empirical formula for enthalpies of TNR solution is calculated by polynomial simulation on the computer.The results show that the formula is ΔsolH=-14.392-988.6b+34.992b1/2.The standard molar enthalpy of solution is determined to be ΔsolHθm=-14.392 kJ·mol-1.The relative apparent molar enthalpies of solution (ΦLi),the relative partial molar enthalpies(Li),enthalpies of dilution (ΔdilH1,2) are also stretched respectively.The thermodynamics of TNR solution was studied by analyzing heat-flux to time curves,the rate constant of reaction and the reaction order were determined to be 1.632×10-3 s-1 and 0.6158,respectively.关键词
