“…SVB or ε is the first-rank parameter in the suggested LSER model for ferrocene solubility and deals with the average equilibrium and chromatographic distribution constants on some SVB (styrene-divinylbenzene) adsorbents . The value of this parameter has an almost direct relationship with the branching of the solvent structure. , According to the positive sign of this scale in eq , we can say that the branched and cyclic solvents are a better options for dissolving ferrocene than n-hydrocarbons with lower structural branches. However, it should be emphasized that eq is a multiparameter model and its final decision depends on the effect of all involved parameters.…”

The solubility of ferrocene in various organic solvents is important because of its application in chemical process and its role as a standard electrochemical probe in nonaqueous systems. A multilinear quantitative structure property relationship (QSPR) model based on theoretical descriptors and a new linear solvation energy relationship (LSER) model based on empirical scales of solvents are suggested for Ostwald solubility coefficient of ferrocene in 35 organic solvents. The constructed models were validated using different statistical approaches such as internal validation and external test set. In addition to excellent external prediction ability, QSPR and LSER models covered 94 and 92% of cross-validated variance, respectively. The proposed models confirmed the role of polar interactions and basicity of solvents during the solvation of ferrocene in organic phase.

“…The two models are equivalent [36] and so are generally referred to as the Snyder-Soczewinski displacement model. The Snyder-Soczewinski model fit and explained normal phase retention data better than the other models [26,37], and has provided understanding of retention on silica [32], alumina [33,34], bonded phases [30] and other phases [38] under normal phase conditions.…”
