Phase behavior of undecane-tetradecane (n-C₁₁H₂₄-C₁₄H₃₀, C₁₁-C₁₄) mixtures in bulk and confined in SBA-15 have been studied using differential scanning calorimetry. The bulk C₁₁-C₁₄ system shows multiple phase regions due to rotator phase. Confined in the pores of SBA-15 (pore diameters 3.8-7.8 nm), the mixtures only show a melting boundary of a straight line and a curve, respectively. In SBA-15 (17.2 nm), phase behavior of themixtures has some similarity to that of the bulk. Under confinement, the phase diagrams of the mixtures vary with the pore size, temperature, and compositions.
