| titleOfInvention | A kind of preparation method of ortho-chlorotolu'ene |
| abstract | The present invention relates to a kind of preparation method of ortho-chlorotolu'ene, specifically refer to using toluene as raw material, Cl 2 For chlorine source, [BMIM] Cl-nZnCl 2 （N=1,2,2.5, n are ZnCl 2 With [BMIM] Cl mol ratio）Acidic ion liquid is catalyst, and catalysis toluene prepares ortho-chlorotolu'ene；The present invention is from [BMIM] Cl-nZnCl 2 （N=1,2 or 2.5）Acidic ion liquid is used as the catalyst of chlorination, Cl 2 For chlorine source, Toluene selective chlorination reaction is carried out；This method can both improve the selectivity of ortho-chlorotolu'ene in product, again can be by [BMIM] Cl-nZnCl isolated from product 2 Ionic-liquid catalyst is reused, and production cost is reduced, beneficial to the important method of ortho-chlorotolu'ene industrialized production. |
