Process for extracting meta-dichlorobenzene from isomer mixtures with mixed alkali metal exchanged X zeolite adsorbents |
| abstract |
A process for separating the isomers of dichlorobenzene from a feed mixture of the same. Separation of the isomers is effected by selective absorption and desorption and is susceptible to various flow schemes for performing continuous adsorptive separations. The process uses an X-type zeolite adsorbent having a mixture of sodium and potassium ions in the exchangeable cationic sites. The desorbent may be an alkyl benzene, such as toluene, xylene, p-diethylbenzene, etc. |
