Separation of ethyltoluene isomers |
| abstract |
A process of separating the ortho, meta and para isomers of ethyltoluene. One aspect employs a ferrierite absorbent which separates the para isomer from a mixture of the same and at least one of the meta and ortho isomers. A second aspect employs a silicalite absorbent which separates the ortho isomer from a mixture of the same and the meta isomer. A third aspect combines the ferrierite and silicalite absorbents in sequence to separate a mixture of the ortho, meta and para isomers into the essentially pure compounds. |
