Abstract : Ultrasonic attenuation and velocity measurements in the critical temerpature region of the binary liquid system beta, beta'-dichloroethyl either + hexane are presented. This system has an upper critical solution temperature at 12.7C. Measurements were taken at frequencies between 1 and 9 MHz. The dependence of both attenuation and velocity on temperature and on frequency was investigated. The temperature dependence of the attenuation compares favorably with the theory of Fixman. However, the frequency dependence of the attenuation cannot be fit by a function that is a single power of frequency. A velocity dispersion is observed. (Author)
