四苯硼酸盐的热化学研究——Ⅱ.一价四苯硼酸盐的标准生成焓

STUDIES ON THERMOCHEMISTRY OF TETRAPHENYLBORATES Ⅱ.STANDARD ENTHALPIES OF FORMATION OF UNIVALENT TETRAPHENYLBORATES

本文用自行建立的精密溶解层热装(?)测定了298.15K时,NH_4BPh_4、KBPH_4、RbBPh_4、CsBPh_4、TlBPh_4、AgBPh_4和HgPh_2七种沉淀反应的反应焓,由此计算了一价四苯硼酸盐的标准生成焓、熵及吉布斯自由能.

Using precision solution calorimeter constructed in this laboratory, the enthalpies of reac tion of seven precipitates of NH4BPh4, KBPh4, RbBPh4, CsBPh4, TlBPh4, AgBPh4 and HgPh2 had been determined at 298.15 K. Further, the standard enthalpies, entropies and Gibbs free energies of formation of univalent tetraphenylborates had been calculated at 298,15 K.
