METHOD FOR SELECTIVE SEPARATION OF XYLENE ISOMER BY USING GUANIDINIUM PARA TOLUENE MONOSULFONATE

摘要

The invention guanidinyl nium p-toluene sulfonate mono selective separation method using xylene isomers relates . ; the invention xylene isomers mixture by mixing old to not de- nium p-toluene sulfonate by reacting a mono guanidinyl nium p-toluene sulfonate mono affinity for different xylene provides a method for selective separation of xylene isomers to separate the isomers . ; the present invention is a mixture of mono guanidinyl nium p-toluene sulfonate having a high affinity for the meta- xylene from a xylene mixture by treatment , and in a mixture of xylene isomers with a simple purification step was able to effectively remove the high-purity meta- xylene .
