EXCESS-ENTHALPIES OF (A CHLORINATED BENZENE PLUS AN ALKANOL) AT THE TEMPERATURE 298.15-K

Excess molar enthalpies HEmwere measured as a function of mole fraction at the temperature 298.15 K and atmospheric pressure for the 16 mixtures {x(C6H5Cl or 1,2-C6H4Cl2or 1,3-C6H4Cl2or 1,2,4-C6H3Cl3) + (1-x)CjH2j+1OH} where j = 1, 3, or 3. An LKB 2107 flow microcalorimeter was used for the measurements. The HEms for these mixtures are discussed in terms of the chloro-groups and also in terms of the carbon chain-lengths of the alkanols. These results are also compared with HEm[x{C6H5(CH3) or 1,2-C6H4(CH3)2or 1,3-C6H4(CH3)2or 1,4-C6H4(CH3)2or 1,2,3,-C6H3(CH3)3} + (1-x)CjH2j+1OH] which have been reported previously. © 1993 Academic Press Ltd.
