Hidratación de etileno

C2H4 + H2O → C2H5OH

Descripción general

Ethylene undergoes acid-catalyzed hydration to form ethanol. This is the primary industrial method for producing synthetic ethanol, using phosphoric acid on a silica support at 300 C and 70 atm. The reaction is exothermic but requires high temperature for kinetic reasons.
