1.3 Synthetic Route

Put 210 kg of 40% fluoroboric acid into the reactor, and slowly add 63~65 kg of basic copper carbonate. Stir while adding to allow CO2 to escape completely. The feed liquid was filtered to remove the unreacted basic copper carbonate, and the clear liquid was transferred to the evaporator and concentrated to 1/10 of the original volume under reduced pressure. It can be cooled and crystallized, centrifugal dehydration, and the finished product is obtained.
