Can phosphate rock and sulfuric acid not react directly?
Thread Content
The reaction between phosphate rock and sulfuric acid occurs in two steps: ① First, the phosphate rock is decomposed by phosphoric acid to produce monocalcium phosphate; ② Then, Ca(H2PO4)2 reacts further with sulfuric acid to yield phosphoric acid. Why can’t phosphate rock react directly with sulfuric acid?
Can’t or still not allowed? By combining these two reaction equations, it is possible to remove the F element at a relatively low cost through stepwise reactions and separation
According to the factory staff, phosphate powder cannot react directly with sulfuric acid
This reaction is reasonable; it should not be used directly in reactions, as both the reactants and products are too dangerous, and the production conditions are also unreasonable.
