Speeds of sound and isentropic compressibilities of alkyl cellosolve with aliphatic alcohols at 308.15K

Speeds of sound are measured in binary mixtures of alkyl cellosolve (2-ethoxyethanol and 2-butoxyethanol) with aliphatic alcohols at 308.15K. Aliphatic alcohols includes methanol, propan-1-ol, butan-1-ol, 2 methyl propan-1-ol, 2-methyl propan-2-ol and pentan-1-ol. Experimental sound speed data are used along with the density values to compute isentropic compressibilities in these mixtures. Deviations in isentropic compressibilities are negative in all the systems except in mixtures containing pentan-1-ol as non-common component, where as an inversion in sign of the function is observed. Further, speeds of sound are evaluated on the basis of Jacobson's free length theory and Schaff's collision factor theroy. The predicted values are in good agreement with the experimental results.
