ACETALDEHYDE Chemical compatibility with O-rings, rubbers, & plastics

Acetaldehyde is a colorless, flammable liquid with a pungent, fruity odor, represented by the chemical formula CH3CHO. It is an important intermediate in the production of various chemicals, including acetic acid, perfumes, and flavors. Acetaldehyde occurs naturally in ripe fruits, coffee, and bread, and is also produced by plants during photosynthesis. Industrially, it is produced by the oxidation of ethanol or the hydration of acetylene. Acetaldehyde is used in the manufacture of plastics, synthetic rubber, and as a solvent in certain applications. However, it is a toxic substance and can cause irritation to the eyes, skin, and respiratory system. Long-term exposure may lead to more severe health effects. Proper handling, storage, and disposal practices are essential to mitigate the risks associated with acetaldehyde.
