Propiedades volumétricas y de transporte para las mezclas binarias de β-pineno + n-dodecano
Resumen
El β-pineno es un derivado de la resina de pino, que se ha propuesto como una de las nuevas fuentes de hidrocarburos para la industria química y de combustibles. Por lo anterior, es necesario estudiar su interacción con otras moléculas orgánicas, como los alcanos lineales. En este trabajo se reportan los valores experimentales para la densidad, la viscosidad dinámica y el índice de refracción a presión atmosférica, para el sistema β-pineno + n-dodecano en todo el intervalo de composiciones y en el intervalo de temperatura de 293.15 a 323.15 K. Se obtuvieron las propiedades derivadas, el volumen de exceso mostró valores positivos, mientras que las desviaciones en la viscosidad y en el índice de refracción mostraron valores negativos. Los resultados se ajustaron a una ecuación empírica, la cual permite predecir los valores de las propiedades volumétricas y de transporte para la mezcla, bajo las condiciones estudiadas. Finalmente, se encontró que las interacciones moleculares son débiles y los valores de las propiedades derivadas dependen principalmente de las diferencias en la estructura molecular.
