  • New: Two methods of recovering hexachlorocyclotriphosphazene

We should be on the hexachlorocyclotriphosphazene this product is not too familiar with, so for its recycling method even less understanding, then in order to let everyone for a good understanding of the product, the following will be detailed for everyone to introduce the knowledge, I hope you read carefully.
1, acid hydrolysis method
In the reaction kettle to the liquid hexachlorocyclotriphosphazene in the appropriate amount of hydrochloric acid or directly into the hydrogen chloride gas, control the acid hydrolysis temperature below 80 ℃ to fully stir until the acid hydrolysis is complete, the acidification process escaped tail gas washed, Alkali washing, drying, compression and other steps after the recovery of methyl chloride gas.
2, hydrolysis method
In the reaction kettle, the appropriate amount of water was added to the trichlorocyclotriphosphazoline distillation residue, and the hydrolysis temperature was controlled to 60 ° C until the hydrolysis was complete. After completion of the hydrolysis, the resulting aqueous solution of methanol and hexachlorocyclotriphosphazene is decolorized by activated carbon, filtered and removed, and vacuum-concentrated. The distillate is methanol, and the concentration of methanol is about 75% product.
