Cupric tetrafluoroborate hydrate - Physico-chemical Properties
| Molecular Formula | B2CuF8H2O |
| Molar Mass | 255.17 |
| Physical and Chemical Properties | Chemical properties Solid copper fluoroborate is bright blue needle-like crystals. There is moisture. It is very soluble in water and easily forms a complex of water and ammonia, so it is very difficult to prepare anhydrous salt. Its typical hydrates are tetrahydrate and hexahydrate. The binding form of this type of compound is hydrated copper fluoroborate [Cu(H2O)n][BF4]2. There is also monohydrate [Cu(BF4)2 · H2O], which is a colorless crystal. Copper fluoroborate hexahydrate has a 2.175 relative density and can be decomposed into BF3, CuF2 and H2O when heated to 40 ℃, and can be decomposed into tetrahydrate at room temperature and vacuum. Both tetrahydrate and monohydrate have strong hygroscopicity. Only when P2O5 is dried for a long time can crystal water be removed. |
| Use | Use 1, can be used as copper and copper alloy electroplating bath composition. It is used as a plating electrolyte for a printing cylinder and a photographic printing cylinder. 2, this product is used for the preparation of copper plating electrolyte. The plating solution can be used for copper plating at high current density, and the coating is fine and smooth. 3, used as copper and copper alloy electroplating solution of raw materials, copper smelting and welding additives, printing and dyeing, photography, etc. |

Cupric tetrafluoroborate hydrate - Uses and synthesis methods
Toxicity
See boron trifluoride.
production method
put the 210kg 40% fluoroboric acid into the reactor, and slowly add 63~65kg of basic copper carbonate. Stir while adding to allow CO2 to escape completely. The feed liquid is filtered to remove the unreacted basic copper carbonate, the clear liquid is transferred to the evaporator, and concentrated to 1/10 of the original volume under reduced pressure. It can be cooled and crystallized, centrifuged and dehydrated to obtain the finished product.
Copper carbonate method fluoroboric acid and basic copper carbonate react in a reactor, filter to remove impurities, and then evaporate to one-tenth of the original volume to produce a finished product of copper fluoroborate. Its 4HBF4 + Cu2(OH)2CO3 & rarr;2Cu(BF4)2 + CO2 + 3H2O
