WebPEP Review 98-06. The subject patent claims the use of the mono- or dipotassium salt of silicotungstic acid or phosphotungstic acid as catalyst for the continuous vapor-phase hydration of ethylene to ethanol wherein unreacted ethylene is recycled back to the hydration reaction. Traditional technology uses supported phosphoric acid as the catalyst. WebEthanol for use as an industrial feedstock or solvent (sometimes referred to as synthetic ethanol) is made from petrochemical feed stocks, primarily by the acid-catalyzed hydration of ethylene: C 2 H 4 + H 2 O → CH 3 CH 2 OH. The catalyst is most commonly phosphoric acid, adsorbed onto a porous support such as silica gel or diatomaceous earth.
