EXCESS VOLUMES AND SPEED OF SOUND FOR M-CHLOROTOLUENE PLUS 2-PROPANOL, PLUS 2-METHYL-1-PROPANOL, AND PLUS 3-METHYL-1-BUTANOL AT 303.15-K

Excess volumes (V(E)) and Isentropic compressibilities (k(s)) of binar y mixtures of m-chlorotoluene with 2-propanol, 2-methyl-1-propanol, an d 3-methyl-1-butanol have been determined at 303.15 K. The excess volu me exhibits inversion in sign in the three mixtures. The data are alge braically smaller than those for mixtures which include toluene in pla ce of m-chlorotoluene. The deviation in isentropic compressibility is negative over the whole range of composition in the three mixtures. Th e deviation is algebraically smaller than that observed for mixtures o f the three alcohols with toluene.
