Question

Which chemical is manufactured by the contact process? Name the catalyst used here.​

Answer 1

Answer:

Platinum was initially used as the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V2O5) is now preferred.

Answer 2

The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was initially used as the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V2O5) is now preferred.

This process was patented in 1831 by British, vinegar merchant Peregrine Phillips. In addition to being a far more economical process for producing concentrated sulfuric acid than the previous lead chamber process, the contact process also produces sulfur trioxide and oleum.
