A kind of separation and purification process of 4-5 fluorophenyl boron compound |
| abstract |
The invention provides a separation and purification process for a 4-5 fluorophenyl boron compound, in particular to the field of chemical technology. Elution was started at 50.1 minutes and adjusted with 100% methanol for an additional 15 minutes. The invention effectively removes the reaction reagent salt and unknown impurities in the compound reaction in the tetrapentafluorobenzene boron compound, thereby improving the purity of the sample, changing the traditional liquid-liquid extraction preparation method, and reducing the loss of the sample. |
