IUPAC Name: Ethanal
Source: Has many important industrial and manufacturing applications but is most importantly used as a gasoline additive and intermediate in organic synthesis.
Summary: Acetaldehyde is both naturally occurring and synthetic chemical. It is found naturally in plants, fruits, and vegetables. It is produced synthetically to create acetic acid and other organic compounds, pharmaceuticals, dyes, rubber, adhesives, plastics, and may be an additive in food for flavor purposes. Acetaldehyde may also be used in gasoline. It is soluble in water up to 1,000,000 mg/L and has a density of 0.7834 g/mL. It has an acid dissociation constant of pKa = 13.57 at 25 C. The compound is classified by the EPA as a Hazardous Air Pollutant (HAPs). A Koc value of 1 indicates very high mobility within soil that may lead to leaching to groundwater. Photolysis, biodegradation, and volatilization are expected to be major fate processes in water and soil.
