Butyraldehyde

Butyraldehyde, also known as butanal, is an organic compound with the formula C_H_O. It is a colorless, flammable liquid with a pungent odor. Butyraldehyde is an important intermediate in the production of various chemicals and is used in the manufacture of resins, plasticizers, and solvents.

Chemical Properties

Butyraldehyde is an aldehyde, characterized by the presence of a carbonyl group (C=O) attached to a terminal carbon atom. It is the simplest aldehyde derived from butane. The compound is miscible with most organic solvents but has limited solubility in water.

Production

Butyraldehyde is primarily produced by the oxo process, also known as hydroformylation, where propylene is reacted with carbon monoxide and hydrogen in the presence of a catalyst to form butyraldehyde. This process is a key step in the industrial production of butanol and other derivatives.

Applications

Butyraldehyde is used as a precursor in the synthesis of various chemical compounds. It is a key intermediate in the production of 2-ethylhexanol, which is further used to produce plasticizers such as Bis(2-ethylhexyl) phthalate.

Plasticizers

Plasticizers are substances added to materials to increase their flexibility, workability, or distensibility. Butyraldehyde is involved in the production of plasticizers that are used in the manufacture of polyvinyl chloride (PVC) products.

Resins and Solvents

Butyraldehyde is also used in the production of resins and solvents. It is a building block for the synthesis of acrylic acid and its esters, which are used in the production of paints, coatings, and adhesives.

Safety and Handling

Butyraldehyde is a flammable liquid and should be handled with care. It can cause irritation to the skin, eyes, and respiratory tract. Proper safety measures should be taken when handling this chemical, including the use of personal protective equipment and adequate ventilation.
