Hello sir,

I am doing my final year project manufacturing of Fluoboric acid ( HBF4) through HF and boric acid used as raw material. water by product.( Product solution ).

In this process i need some data. what is the enthalpy reference point boric acid and HF.

And also i can calculate HF enthalpy ( i.e., Input enthalpy ) by using enthalpy concentration diagram for 70% HF at 1 atm and 25 deg C . It comes around -279 KJ/Kg. how i can calculate solid boric acid at 25 deg C.

Reaction carried out 55- 50 deg C. what is the std heat of reaction for this reaction ? Also what is the enthalpy reference point Fluoboric acid solution.

4HF + H₃BO₃ = HBF₄ + 3H₂O
If i get data i move further step calculations.

i didn't find any data on websites and other books.


Help us ....
