propaldehyde

Propaldehyde, also known as propanal, is an organic compound with the chemical formula CH3CH2CHO. It is a simple aldehyde, characterized by a carbonyl group bonded to an ethyl group and a hydrogen atom. Propanal is a colorless liquid at room temperature with a pungent, fruity odor. It is soluble in water and many organic solvents.

Propanal is produced industrially through the hydroformylation of ethylene, a process where ethylene reacts with carbon monoxide and hydrogen in the presence of a catalyst. Another common method involves the oxidation of propanol. Its primary use is as an intermediate in the synthesis of other chemicals. For example, it is used in the production of propionic acid, which finds applications in food preservation and the synthesis of pharmaceuticals and plastics. Propanal is also a precursor for the production of various alcohols and other organic compounds.

In terms of safety, propanal is considered flammable and should be handled with care, avoiding open flames and sparks. It can cause irritation to the skin, eyes, and respiratory tract. Exposure limits are established to minimize health risks in occupational settings. It is important to consult safety data sheets for detailed handling and storage information.
