3,4-Dichloro-6-(trifluoromethyl)toluene synthesis
- Product Name:3,4-Dichloro-6-(trifluoromethyl)toluene
- CAS Number:74483-51-5
- Molecular formula:C8H5Cl2F3
- Molecular Weight:229.03
500 ml of hydrogen fluoride, 600 ml of carbon tetrachloride and 140 g of 3,4-dichlorotoluene are reacted at 110° to 115° C. and 18.5 to 19.5 bar pressure. 151 g of a stubstance containing, in addition to 79.1% by weight of 3,4-dichlorotoluene, 20.2% by weight of 2-methyl-4,5-dichloro-benzotrifluoride, are obtained, corresponding to 74% of the theoretical yield, relative to 3,4-dichlorotoluene converted.
