Abstract Solubilities of tetraphenylarsonium tetraphenylborate (Ph 4 AsB‐Ph 4 ) in water, methanol, ethanol, 1‐propanol, 1‐butanol, 1‐pentanol, 1‐hexanol and 1‐octanol at T = 293.2, 298.2, 303.2 and 308.2 K have been determined by spectrophotometry. The standard transfer Gibbs energy (Δ tr ‐G 0 w‐s ) and entropy (Δ tr ‐G 0 w‐s ) of Ph 4 AsBPh 4 from water to the n ‐alkanols at temerature from 293.2 K to 308.2 K have been obtained. Furthermore, the contribution of microscopic interaction to the standard Gibbs energy of transfer for Ph 4 AsBPh 4 was calculated and discussed. The results show that the effect of hydrophobic interaction of Ph 4 AsBPh 4 on its transfer process is the most important factor. According to the thermodynamical principle, the transfer process of Ph 4 AsBPh 4 from water to the n ‐alkanols is the entropy dominated.
