What is the purpose of adding acid to ethylene oxide?

Reply #22020-07-06

Ethylene oxide readily reacts with acids; therefore, it can be used as an antacid added to certain substances to reduce their acidity or to prevent them from becoming acidic over time. For example, in the production of chlorinated butyl rubber, if ethylene oxide is added to the solution of isobutylene and isoprene copolymer prior to chlorination, the final product can be made completely free of alkali washing and water washing.

Ethylene oxide can explode when heated! Moreover, due to its low boiling point, it will evaporate into the atmosphere when heated, and it is toxic! To turn it into a stable and non-toxic molecule, a small amount of dilute hydrochloric acid is added; under acid catalysis, polyethers are formed
