Separation of xylene isomer from xylene mixture by selective inclusion using guanidinium ortho¡ªterphenyl 4,4¡¯¡ªdisulfonate host compound

摘要

The invention guanidinyl nium ortho-terphenyl of 4,4'-sulfonate host molecules relates to a method for separating xylene isomers using the optional port jeopneung ; The present invention is a mixture of xylene isomers phrase not de-nium ortho-terphenyl reaction by mixing 4,4'-sulfonate was then guanidinyl nium ortho-emitter using a selective Four jeopneung of phenyl 4,4-di-sulfonate provides a method for separating the xylene isomers, characterized by separating the xylene isomers ; The present invention is not di-nium sphere having a high affinity for p-xylene from ortho-xylene mixture - by mixing the terphenyl 4,4'-sulfonate by treatment of the xylene isomers with a simple process mixture was able to be purified in a high efficient separation of high purity para-xylene.
