526-530Excess volumes for the
binary liquid mixtures of methyl butyrate with bromobenzene, chlorobenzene
and nitrobenzene have been calculated from the density data at 303 K, 308 K and 313 K as a function of
composition. Values of excess volumes (VE)
for all the systems studied are found to be highly negative over
the entire range of composition. The negative values of VE were found to
increase with increase in temperature
