| titleOfInvention | Method for selectively absorbing and separating mixed toluene dichloride |
| abstract | The invention relates to a method for separating mixed toluene dichloride, in particular to method taking zeolite molecular sieve as adsorbent to selectively absorb and separate mixed toluene dichloride. Modified KL molecular sieve serves as adsorbent, and the mixed toluene dichloride is separated according to a separation method of performing rectification and then adsorption stripping or performing adsorption stripping and then rectification. The modified KL molecular sieve is prepared through a special method, which absorbs 2.4-toluene dichloride, 2.5-toluene dichloride and 3.4-toluene dichloride, and does not absorb 2.6-toluene dichloride which is the main product, so that desorbent can not be led into 2.6-toluene dichloride during the separation process, and the purity of 2.6-toluene dichloride is improved. |
