Phase behavior of normal decane-dodecane(n-C_(10)H_(22)-C_(12)H_(26),C_(10)-C_(12)) system confined in SBA-15(Santa Barbara Amorphous,pore diameters 3.8,7.8,and 17.2 nm) has been studied by using differential scanning calorimetry.It has been found solid-liquid phase diagram of the C_(10)-C_(12)/SBA-15 system is composed of a straight line(3.8 nm),a curve(7.8 nm) and a loop line (17.2 nm).The growth of the phase diagram clearly shows the size effect on phase behavior of binary alkanes.Phase behavior has been compared among the systems C_(10)H_(22)-C_(12)H_(26)/SBA-15,C_(12)H_(26)-C_(14)H_(30)/SBA-15 and C_(14)H_(30)-C_(16)H_(34)/SBA-15.
Phase behavior of normal decane-dodecane (n-C_ (10) H_ (22) -C_ (12) H_ (26), C_ (10) -C_12) system confined in SBA-15 diameters 3.8, 7.8, and 17.2 nm) has been studied by using differential scanning calorimetry. It has been found that the solid-liquid phase diagram of the C_ (10) -C_ (12) / SBA-15 system is composed of a straight line 3.8 nm), a curve (7.8 nm) and a loop line (17.2 nm). The growth of the phase diagram shows the size effect on phase behavior of binary alkanes.Phase behavior has been compared among the systems C_ (10) H_ (22) -C 12 H 26 / SBA-15 C 12 H 26 C 14 H 30 / SBA-15 and C 14 H 30 C - 16) H_ (34) / SBA-15.
