METHOD AND APPARATUS FOR SEPARATING ALKYL AROMATIC HYDROCARBON |
摘要 |
A method for separating an alkyl aromatic hydrocarbon, comprising the steps of: adding a first diluent and an extraction agent comprising a superstrong acid to a mixture containing the alkyl aromatic hydrocarbon and at least one isomer thereof to carry out acid-base extraction, thereby forming a complex of the alkyl aromatic hydrocarbon and the superstrong acid, and subsequently separating the complex from the mixture; and adding a release agent having a base degree of 0.06 to 10 relative to the alkyl aromatic hydrocarbon and a second diluent to the complex to carry out complex exchange between the alkyl aromatic hydrocarbon and the release agent, thereby separating the alkyl aromatic hydrocarbon from the complex. |
