Ethylene (C 2 H 4 O) and propylene oxide (C 3 H 6 O) react with water to form ethylene and propylene glycol. However, by normal scrubbing standards, the reaction is very slow and an acid catalyst such as H 2 SO 4 is recommended to reduce the contact time required. Even then, a larger reaction tank is typically recommended to maximize the hydrolysis reaction.
