guanidinyl nium meta- terphenyl- 4,4 '- di -sulfonate isomers of xylene by selective separation methods

摘要

The invention guanidinyl nium meta- xylene using a phenyl- 4,4'- site sulfonate relates to a method of selectively separating isomers Wren ; the present invention is not de- nium meta- xylene isomer mixture phrase - by reacting a mixture of 4,4'- terphenyl sulfonate guanidinyl nium meta- terphenyl affinity for 4,4'- sulfonate provides a method for selective separation of xylene isomers to separate the different xylene isomers ; the invention of xylene isomers by guanidinyl nium showing the different affinity meta- terphenyl- 4,4'- di- sulfonate was used to be able to efficiently separate and purify the xylene isomers with a simple process in a mixture of xylene isomers
