中文摘要: |
测量了298.15-328.15K温度范围内四丁基氟化铵在20(wt)%-80 (wt)% H2O/DMF混合溶液中的电导率,测得的电导率分别通过Kray-Bray方程和Shedlovsky方程分析,推导出了四丁基氟化铵在H2O-DMF混合溶液中的摩尔极限电导、缔合常数和离解常数,并计算出缔合反应的热力学参数(△Ga,△Ha,△Sa);同时探讨了温度和混合溶剂的组成对摩尔极限电导、缔合常数和热力学参数的影响。 |

Conductance measurements at temperatures range from 298.15 to 328.15k were performed for tetrabutylammonium fluoride(TBAF) in 20(wt)%-80 (wt)% water/DMF mixtures. The conductivity data had been analyzed using Kraus-Bray and Shedlovsky models, the limiting equivalent conductance, the association constants, dissociation constants and thermodynamic parameters of association(△Ga,△Ha,△Sa)for TBAF were calculated and discussed based on the effect of the temperature and the composition of solvent mixture on them. |
