Comportamiento acústico y volumétrico de las mezclas binarias de valeronitrilo + propanoato de propilo y valeronitrilo + propanoato de butilo entre 278,15 y 318,15K
Densities and speeds of sound of the binary mixtures valeronitrile/propyl propanoate and valeronitrile/butyl propanoate were determined at atmospheric pressure and at a temperature range which goes from 278.15 to 318.15K every 5K. With the experimental data, we calculated the following physicochemic...

| Summary: | Densities and speeds of sound of the binary mixtures valeronitrile/propyl propanoate and valeronitrile/butyl propanoate were determined at atmospheric pressure and at a temperature range which goes from 278.15 to 318.15K every 5K. With the experimental data, we calculated the following physicochemical properties: VE,, E, u, S y SE; these results were fitted with the polynomial equation of Redlich-Kister. The studied binary mixtures showed negative values of VE, E, u y SE in the whole range of composition and at all temperatures. The prediction of the speed of sound was performed with the models proposed by Nomoto, Ernst and Van Dael. |
