✦ Synopsis

The excess enthalpies H E m of [x {BrCH2Cl or BrCH2CH2Cl or BrCH2CH2CH2Cl or BrCH2(CH2)2CH2Cl}+(1x){CH3(CH2)5CH3 or CH3(CH2)14CH3 or c-(CH2)6} have been measured at the temperature 298.15 K. Mixing was endothermic at all x and the H E m s were found to vary in the sequence: BrCH2CH2Cl q BrCH2Cl q BrCH2CH2CH2Cl 1 BrCH2(CH2)2CH2Cl for mixing with CH3(CH2)5CH3. This behaviour is similar to that found for mixing with CH3(CH2)14CH3 or c-(CH2)6. From the results, qualitative information could be obtained about the so-called ''proximity effect''.
