CH3CHCHO

CH3CHCHO is the chemical formula for propanal, also known as propionaldehyde. It is an organic compound with the aldehyde functional group. Propanal is a colorless liquid with a pungent, fruity odor. Its molecular weight is 58.08 g/mol. The boiling point of propanal is 48.8 degrees Celsius, and its melting point is -81 degrees Celsius. It is soluble in water and many organic solvents.

Propanal occurs naturally in some foods, including fruits and cheese, and is also produced during the fermentation of alcohol. Industrially, it is synthesized primarily through the hydroformylation of ethylene. This process involves reacting ethylene with carbon monoxide and hydrogen in the presence of a catalyst.

The primary use of propanal is as an intermediate in the production of other chemicals. It is used in the synthesis of propionic acid, which is a preservative in animal feed and a component in some herbicides and pharmaceuticals. Propanal is also a precursor for the production of certain alcohols, plastics, and perfumes. In some applications, it can be used as a solvent. Due to its flammable nature and potential for irritation, propanal should be handled with appropriate safety precautions.
