Mezclas binarias de líquido iónico con solvente molecular: Predicción del volumen de exceso molar desde índices de refracción
Resumen
El volumen de exceso molar de 30 mezclas binarias que contienen líquidos iónicos de imidazolio con diferentes solventes moleculares: (metanol, etanol, 1-propanol, 2-propanol, acetona, 2- butanona, 2-pentanona, acetato de metilo, acetato de etilo, acetato de butilo, carbonato de dimetilo, carbonato de dietilo, nitrometano, 1,3-dicloropropano y etilenglicol),se predice desde datos de índice de refracción, usando tres tipos de métodos acoplados con diferentes reglas de mezcla para el cálculo del índice de refracción: Lorentz-Lorenz, Dale-Gladstone, Eykman, Arago- Biot, Newton y Oster. En estos sistemas, las interacciones moleculares y las fuerzas intermoleculares provocan, durante la mezcla, desviaciones positivas o negativas del comportamiento ideal. Los resultados obtenidos se analizan en términos de la naturaleza del líquido iónico y solvente molecular.Descargas
