3,4,5,6-Tetrafluorophthalonitrile is a delicate molecule with tetrafluorosubstituted benzene ring and dinitrile functional group. The preparation method is not easy and needs to be strictly implemented.

First, raw material selection

Use tetrafluorobenzene as the base material, assisted by cyaniding reagent and suitable catalyst. The raw material must be pure, free of water and impurities, in order to obtain high-purity products.

Second, preliminary cyanidation

In an organic solvent (such as dimethylformamide), add hydrogen cyanide or sodium cyanide to tetrafluorobenzene, and with the help of catalysts (such as copper powder, copper salt), promote the fixed-point replacement of nitrile based on the ortho position of the benzene ring.

Third, reaction conditions

The heating temperature should be controlled at 120 to 160 degrees Celsius, and the reaction time ranges from several hours to dozens of hours. However, it is necessary to stir evenly to ensure the complete reaction.

Fourth, post-treatment

After the reaction is completed, cool and filter to remove solid impurities. Wash with water to remove residual inorganic salts, and then recrystallize and purify with organic solvents.

Fifth, purification process

Recrystallization uses mixed solvents such as ethanol and acetone, and repeated crystallization ensures a purity of more than 99%. Column chromatography can also be used to assist purification.

Sixth, safety and environmental protection

Cyanide is highly toxic in the reaction, and leakage is strictly prohibited during operation. Waste liquid must be specially treated and must not be discharged at will. Protecting nature is the virtue of modern craftsmen.
