Selective Separation of Xylene Isomers Using Guanidinium Meta-terphenyl 4,4'-Sulfonate |
| abstract |
The present invention relates to a method for the selective separation of xylene isomers using guanidinium meta-terphenyl 4,4'-disulfonate.n n n The present invention is made by reacting a mixture of guanidinium meta-terphenyl 4,4'-disulfonate with a xylene isomer mixture, thereby improving affinity for guanidinium meta-terphenyl 4,4'-disulfonate. Provided is a method for selectively separating xylene isomers that separates different xylene isomers.n n n The present invention is to efficiently separate and purify xylene isomers through a simple process in a mixture of xylene isomers using guanidinium meta-terphenyl 4,4'-disulfonate showing different affinity for each xylene isomer. Made it possible. |
