association constant
1.The Thermodynamics of Aqueous Borate Solutions——4. The Standard Association Constant of Ion Pair [CaB(OH)_4]~+
2.Using Hildebrand-Benesi equation,the molar ratio was found to be 1∶1 and association constant was 533.6 L/mol.
3.Relations between the association constant k of 2-Butanol and temperature were derived, and associated model was used to predict the VLE data for binary systems of 2-Butanol──n-Butane and 2-Butanol──2-Butene at 0. 5MPa and 0.7Mpa.
4.The association constant values, K, for the interaction of α CD 1, β CD 2, heptakis(2,6 di o methyl) β CD 3 and γ CD 4 with D ,L ,D,L phenylalanine (Phe) were determined by means of UV vis spectroscopy.
5.Mean activity coefficients of LiCl in LiCl Li 2B 4O 7 H 2O system have been determined in the ionic strength ranging from 0.01 to 2.50mol·kg -1 at 298.15K by the method of EMF using a pair of lithium ion selective electrode and Ag/AgCl electrode. Stoichiometric association equilibrium constant K m and Pitzer ion interaction parameters were evaluated from present measurements by using multiple regression and iterative method.
