Butyraldehyde, also known as butanal, is a colorless liquid with a characteristic fruity odor. It is used as a solvent, in the manufacturing of lubricants, rubber, plastics, and other products, and as a flavoring agent in food. Butyraldehyde is also used as a precursor in the synthesis of pharmaceuticals.
When rubber is exposed to butyraldehyde, it can cause the rubber to become brittle and cracked due to the oxidation process. It can also cause the rubber to swell and weaken, resulting in cracking and tearing. In addition, exposure to UV light can cause the rubber to discolor, fade, and crack. High temperatures and concentrations of butyraldehyde can also cause the rubber to become sticky.
