CH32CHCHO

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. It is soluble in water and most organic solvents.

Propanal can be synthesized through several methods. One common method is the hydroformylation of ethylene, a process that adds carbon monoxide and hydrogen to ethylene in the presence of a catalyst. It can also be produced by the oxidation of 1-propanol.

The chemical properties of propanal are characteristic of aldehydes. It readily undergoes oxidation to form propanoic acid. It can also participate in various addition reactions at the carbonyl group, such as reactions with nucleophiles. Propanal can undergo self-condensation reactions, like the aldol condensation, to form larger molecules.

Propanal has various industrial applications. It is used as an intermediate in the synthesis of other chemicals, including propanoic acid, which is used in preservatives and flavoring agents. It also finds use in the production of plastics, pharmaceuticals, and fragrances. Due to its flammability and potential for irritation, proper handling and safety precautions are necessary when working with propanal.
