Abstract A study has been made of the kinetics of the vapor‐phase hydration of acetylene over a zinc phosphate‐phosphoric acid‐activated carbon catalyst. Rates of acetylene hydration were measured in a fixed bed flow reactor operated at low conversions. The majority of the data was obtained at 350°C. The amounts of acetylene hydrated were determined by analyzing the products for acetaldehyde, crotonaldehyde and acetic acid. The catalyst activity diminished with increasing process time. The reaction rate data obtained at low conversions of acetylene were correlated by an empirical equation and a tentative mechanism suggested which is consistent with this equation. The data obtained in the low conversion (differential) reactor have been compared to the data obtained using a fixed bed flow reactor operated at high conversions, using the integrated form of the rate equation.
