| introduction | bromopentafluorobenzene, also known as pentafluorobenzene, is an important new fine chemical, which is not only an intermediate of pesticide, medicine and liquid crystal materials, but also an intermediate of olefin polymerization catalyst, and has a wide range of applications and development prospects. |
| use | bromopentafluorobenzene is a polyfluorinated chemical substance widely distributed in the environment and released due to its use in different household and industrial products. Bromopentafluorobenzene is also used in the synthesis of phenylalanine and has herbicide activity. Medicine, pesticides, liquid crystal material intermediates. |
| preparation | add 208g of chloroform and 38.5g of bromine (0.24mol) to a 250mL four-mouth bottle, cool to -5 ℃, introduce 17g of chlorine (0.24mol), drop the obtained chloroform solution of bromine chloride into a reactor containing 80g of pentafluorobenzene (0.48mol) and 12.8g of aluminum trichloride (0.1mol) at 35 ℃, after 12 hours of heat preservation and stirring, 100g of brominated pentafluorobenzene was obtained by distillation under reduced pressure after post-treatment and distillation under reduced pressure with 84.5% yield. |
