【 摘 要 】

Ultrasonic speed for a mixture of dodecane and 1-butanol were calculated from (288.15 to318.15K) over the whole composition range at atmospheric pressure, from the experimental work of J.Peleterio. Flory(non-associated), Ramaswamy and Glinski (associated) were used to predict thebehaviour and molecular interactions of binary system. Deviation in ultrasonic speed (∆U) was used inRedlich Kister polynomial to determine the numerical coefficients and standard deviation. Isentropiccompressibility was also calculated over the entire composition range at various temperatures. Eyring’stheory-based McAllister models were used to correlate the thermoacoustic properties. Calculation bythese models were compared with the experimental values to test extent of the molecular interactions.Ramaswamy was found more consistent with experimental values in comparison to Flory.
