asetaldehüüd

Asetaldehüüd, also known as ethanal, is an organic compound with the chemical formula CH3CHO. It is a colorless, volatile liquid with a pungent, fruity odor. Asetaldehüüd is the simplest aldehyde, meaning it contains a formyl group (-CHO) attached to a methyl group (-CH3). It is highly soluble in water and miscible with many organic solvents.

In nature, asetaldehüüd is a significant intermediate in cellular metabolism. It is produced during the fermentation of carbohydrates by yeasts, which is a key process in the production of alcoholic beverages. Asetaldehüüd is also formed during the metabolism of ethanol in the human body, and its accumulation can contribute to the unpleasant symptoms of a hangover.

Industrially, asetaldehüüd is primarily produced by the oxidation of ethylene or ethanol. It serves as a crucial building block in the synthesis of a wide range of chemicals, including acetic acid, acetic anhydride, and ethyl acetate. These derivatives find applications in the production of plastics, solvents, pharmaceuticals, and fragrances.

Asetaldehüüd is flammable and can form explosive mixtures with air. It is also an irritant to the eyes, skin, and respiratory system. Exposure to high concentrations can lead to dizziness, nausea, and headaches. Due to its reactivity and potential health hazards, proper handling procedures and safety precautions are essential when working with asetaldehüüd.
