ACETIC ANHYDRIDE Resistant O-Rings and Seals
Acetic anhydride, also known as ethanoic anhydride and acetic oxide, is a colorless, flammable organic compound with the chemical formula (CH3CO)2O. It is widely used as a reagent in organic synthesis, as a solvent for cellulose acetate, and for production of acetic acid, vinyl acetate, and acetate esters.
Common types of failure when rubber is exposed to acetic anhydride include cracking and discoloration due to oxidation and hydrolysis. In addition, acetic anhydride is an extremely strong acid and can cause swelling, softening, and embrittlement of rubber materials. It can also cause damage to the rubber’s surface, leading to premature wear and tear.
