In the chemical industry, it is often used as a catalyst, a biochemical reagent, and a mordant for basic dyes.
Silicotungstic acid can be used to catalyze the reaction of preparing ethyl acetate from acetic acid and ethylene:
C2H4+CH3COOH →CH3COOC2H5
When oxidizing ethylene to produce acetic acid, silicotungstic acid is used as a catalyst:
C2H4+ O2→CH3COOH
This method claims to meet the needs of green chemistry more than the Monsanto method. When silicotungstic acid is dispersed in silica gel at a weight percentage of 20-30%, its catalytic effect is the best.
