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 met hyl propan-1-ol, 2-methyl propan-2-ol and pentan-1-ol. Experimental so und speed data are used along with the density values to compute isent ropic compressibilities in these mixtures. Deviations in isentropic co mpressibilities are negative in all the systems except in mixtures con taining pentan-1-ol as non-common component, where as an inversion in sign of the function is observed. Further, speeds of sound are evaluat ed on the basis of Jacobson's free length theory and Schaff's collisio n factor theroy. The predicted values are in good agreement with the e xperimental results.
