In this work we report the excess molar volumes, [Formula: see text] for the miscible mixtures {xc-C5H10 + (1 − x)CH3OH} and {xc-CkH2k + (1 − x)ClH2l+1OH} where k = 5, 6, 7, 8, or 10 and l = 2 or 3. The [Formula: see text] results are discussed in terms of the size of the cycloalkane ring and the type of alcohol. Key words: Excess volumes, cycloalkane + alkanol.
