MOSCED (short for “modified separation of cohesive energy density" model) is a thermodynamic model for the estimation of limiting activity coefficients (also known as activity coefficient at infinite dilution). From a historical point of view MOSCED can be regarded as an improved modification of the Hansen method and the Hildebrand solubility model by adding higher interaction term such as polarity, induction and separation of hydrogen bonding terms. This allows the prediction of polar and associative compounds, which most solubility parameter models have been found to do poorly. In addition to making quantitative prediction, MOSCED can be used to understand fundamental molecular level interaction for intuitive solvent selection and formulation.

  • MOSCED (short for “modified separation of cohesive energy density" model) is a thermodynamic model for the estimation of limiting activity coefficients (also known as activity coefficient at infinite dilution). From a historical point of view MOSCED can be regarded as an improved modification of the Hansen method and the Hildebrand solubility model by adding higher interaction term such as polarity, induction and separation of hydrogen bonding terms. This allows the prediction of polar and associative compounds, which most solubility parameter models have been found to do poorly. In addition to making quantitative prediction, MOSCED can be used to understand fundamental molecular level interaction for intuitive solvent selection and formulation. In addition to infinite dilution, MOSCED can be used to parameterize excess Gibbs Free Energy model such as NRTL, WILSON, Mod-UNIFAC to map out Vapor Liquid Equilibria of mixture. This was demonstrated briefly by Schriber and Eckert using infinite dilution data to parameterize WILSON equation. The first publication is from 1984 and a major revision of parameters has been done 2005. This revised version is described here. (en)
  • MOSCED of Modified Separation of Cohesive Energy Density is een thermodynamisch model voor het afschatten van de grensactiviteitscoëfficiënten, die de afwijking van ideaal oplosgedrag bij oneindige verdunning kwantificeren. Hoe groter de waarde des te vluchtiger is de opgeloste stof meer dan dat deze puur is. Waarden kleiner dan ėėn geven aan dat de opgeloste stof associeert met het oplosmiddel en daardoor minder snel verdampt. Vanuit een historisch oogpunt kan MOSCED gezien worden als een verbetering op de eerder ontwikkelde activiteitsmodellen: en het . De eerste publicatie van het MOSCED model dateert van 1984, maar een grote verbetering werd in 2005 gemaakt. Deze laatste versie wordt hier besproken. (nl)
