Inputting molecular weights into a multilayer perceptron to estimate refractive indices of dialkylimidazolium-based ionic liquids-A purity evaluation

- Neural networks to estimate the refractive index of imidazolium-based ionic liquids.
- Purity determination by comparison of estimated and experimental refractive indices.
- Only the molecular weights are required as previously known information.
- Chemical approach by relating molecular weights and refractive indices.
- Successful results obtained with both bibliographical and experimental data.
