Method for isomerizing halogenated ethylbenzene and method for separating halogenated ethylbenzene isomers |
摘要 |
A method for isomerizing a halogenated ethylbenzene characterized by bringing the same into contact with an acidic zeolite containing at least one metal selected among metals of Groups 7 to 11; and a method of efficiently isolating a m-halogenated ethylbenzene from a mixture of halogenated ethylbenzene isomers by adsorption using a specific zeolite X or Y as the adsorbent. The isomerization method enables a halogenated ethylbenzene to be efficiently isomerized with the zeolite catalyst. The separation method enables m-chloroethylbenzene to be efficiently separated from a mixture of chloroethylbenzene isomers by using a specific zeolite as the adsorbent.
