Corresponding-States Model for the Correlation andPrediction of the Surface Tension of Silanes
2020
A new corresponding-states model
for the calculation of the surface
tension of silanes is proposed. It requires, as input properties,
the critical point temperature, the minimum temperature at which one
data for the surface tension is available, and the corresponding maximum
value of this property. It includes two adjustable coefficients, which
are calculated by considering the data available at the DIPPR database
for 5 silanes. Then the model is applied to predict the surface tension
values for other 31 silanes. Averaged absolute deviations below 12%
are found for the 36 silanes, being below 5% for 33 of them. Results
obtained by using the other five corresponding-states models available
in the literature, one of them specifically designed for silanes,
are also obtained. That proposed here gives clearly the best overall
results.
