摘要：A method for separating an alkyl aromatic hydrocarbon, the method having a
step of adding a first diluent and an extractant having a superacid to a mixture comprisingthe alkyl aromatic hydrocarbon and one or more isomers thereof to carry out an acid-base extraction to thereby form a complex of the alkyl aromatic hydrocarbon with thesuperacid, and thereafter separating the complex from the mixture, and a step of addingan eliminating agent having a relative basicity in a range of 0.06 to 10 with respect to thealkyl aromatic hydrocarbon and a second diluent to the complex, and carrying outcomplex exchange of the alkyl aromatic hydrocarbon for the eliminating agent tothereby separate the alkyl aromatic hydrocarbon from the complex.
