The excess molar volumes\(V^{E}_M\) have been determined using a vibrating-tube densi-

meter as a function of mole fraction x at 298.15 K and atmospheric pressure for the twelve mixtures _XH_2m+1 ,C_mCO₂, CH₂ , (m =1,2,3) + (1 — x) ClC_n,H_2n+1 , (n = 5,6,7,8). All these mixtures exhibit a positive \(V^{E}_M\) which increases quasi-regularly with increasing size of the 1-chloroalkane. The results indicate the presence of specific inter­actions. A qualitative interpretation of the results is presented.
