1Butanal

1-Butanal, also known as butyraldehyde, is an organic compound with the chemical formula CH3CH2CH2CHO. It is an aldehyde derived from butane, featuring a formyl group (-CHO) at the end of a three-carbon chain. 1-Butanal is a colorless liquid with a pungent, fruity odor. It is soluble in organic solvents and moderately soluble in water.

This compound is primarily produced industrially through the hydroformylation of propylene. This process involves reacting propylene with synthesis gas (a mixture of carbon monoxide and hydrogen) in the presence of a catalyst, typically a rhodium or cobalt complex, to yield a mixture of n-butyraldehyde and isobutyraldehyde. 1-Butanal is the linear isomer.

1-Butanal is a significant intermediate in the chemical industry. It is a precursor to a wide range of chemicals, including butanol, butyric acid, and various plasticizers. Butanol, for example, is produced by the hydrogenation of 1-butanal. Its derivatives find applications in the production of solvents, coatings, and polymers. Due to its reactivity, 1-butanal is also used in the synthesis of perfumes and flavorings. It is important to handle 1-butanal with care as it is flammable and can be irritating to the skin, eyes, and respiratory system.
