Propionaldehyde Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Definition

ChEBI: An aldehyde that consists of ethane bearing a formyl substituent. The parent of the class of propanals.

General Description

A clear colorless liquid with an overpowering fruity-like odor. Less dense than water. Flash point 15°F. Vapors are heavier than air.

Air & Water Reactions

Highly flammable. Soluble in water.

Reactivity Profile

Propionaldehyde may form explosive peroxides. Reacts vigorously with oxidizing agents. Explosive in the form of vapor when exposed to heat or flame [Lewis]. Incompatible with strong bases and strong reducing agents. Vigorous polymerization reaction with methyl methacrylate. Polymerization may also occur in the presence of acids or caustics .

Health Hazard

Vapors will irritate nose and throat, and may cause nausea and vomiting. Liquid causes eye irritation.

Fire Hazard

Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back.

Purification Methods

the aldehyde with CaSO4 or CaCl2, and fractionally distil it under nitrogen or in the presence of a trace of hydroquinone (to retard oxidation). Blacet and Pitts [J Am Chem Soc 74 3382 1952] repeatedly distilled the middle fraction in a vacuum until it no longer gave a solid polymer when cooled to -80o. It is stored with CaSO4. [Beilstein 1 IV 3165.]
