Phase behavior of binary system of bromobenzene-chlorobenzene confined in SBA-15 and MCM-41
摘要:
Phase behavior of binary system of bromobenzene-chlorobenzene (C6H5Br-C6H5Cl) confined in SBA-15 and MCM-41 (pore diameter 8 nm, 3.8 nm, respectively) has been investigated by means of differential scanning calorimetry (DSC). Phase diagram of C6H5Br-C6H5Cl system confined in SBA-15 is a type of the complete miscible both in liquid and solid state, the same phase behavior as the bulk system. However, the phase diagram comprises only one boundary line, which is shifted down 22-36 K with respect to the bulk system. C6H5Br, C6H5Cl or the mixture within nanopores of MCM-41 is nonfreezing. The different phase behavior of the system confined in SBA-15 and MCM-41 is thought mainly due to the relative size of pore to molecule.

However, the phase diagram comprises only one boundary line, which is shifted down 22-36 K with respect to the bulk system. C6H5Br, C6H5Cl or the mixture within nanopores of MCM-41 is nonfreezing. The different phase behavior of the system confined in SBA-15 and MCM-41 is thought mainly due to the relative size of pore to molecule.
