SPEED OF SOUND AND ISENTROPIC COMPRESSIBILITIES OF TRICHLOROETHYLENE WITH BRANCHED ALCOHOLS AT 303.15 K

The speed of sound for the binary mixtures of trichloroethylene with b ranched alcohols has been determined at 303.15 K. The branched alcohol s include 2-propanol, 2-methyl-1-propanol, 3-methyl-1-butanol, 2-butan ol, and 2-methyl-2-propanol. Further, isentropic compressibilities (K- s) and deviation in isentropic compressibilities (Delta K-s) have been computed from the sound velocity and density data derived from excess volumes. The results show that Delta K-s values are positive over the entire range of composition for the systems trichloroethylene + 3-met hyl-1-butanol, + 2-butanol, and + 2-methyl-2-propanol, and an inversio n of sign from negative to positive is observed for the remaining syst ems trichloroethylene + 2-propanol and + 2 methyl-1-propanol.
