[Description]

Propionaldehyde is a volatile liquid substance which consists of one carbonyl group and its characteristic functional group. The main functional group is an aldehyde which classifies propionaldehyde in the carbonyls. The main trunk of this substance is a short aliphatic chain. The carbonyl group determines, to a large extent, its chemical properties and most importantly its nucleophilic property. Propionaldehyde is oxidized very easily.
[Appearance]

Propionaldehyde is a colorless liquid. Very strong, intensive fruit odor

[Uses]

Manufacture of propionic acid, polyvinyl, and other plastics; synthesis of rubber chemicals; disin- fectant; preservative.
[Uses]

Propionaldehyde is produced by the oxo reaction of ethylene with carbon monoxide and hydrogen. n-Propyl alcohol is produced by hydrogenation of propionaldehyde, and propionic acid is made by oxidation of propionaldehyde.
n-Propyl alcohol is used as solvent in printing inks and as an intermediate in the preparation of agricultural chemicals. Propionic acid is used as a grain preservative as, for example, in preventing spoilage of wet corn used as animal feed. The use of propionic acid as a grain preservative is an alterna tive to drying by heating, which consumes fuel, and is considered mostly when fuel is expensive.

[Safety Profile]

Moderately toxic by skin contact, ingestion, and subcutaneous routes. Mddly toxic by inhalation. A skin and severe eye irritant. Flammable liquid. Dangerous fire hazard when exposed to heat or flame; reacts vigorously with oxidizers. Explosive in the form of vapor when exposed to heat or flame. Vigorous polymerization reaction with methyl methacrylate. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

Hazard InformationBack Directory
[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.
[Reactivity Profile]

PROPIONALDEHYDE(123-38-6) 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 .
[Air & Water Reactions]

Highly flammable. Soluble in water.
[Hazard]

Flammable, dangerous fire risk, explosive limits in air 3.0–16%. Upper respiratory tract irri- tant.
[Health Hazard]

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

Used as a synthetic flavoring; as a disinfectant and preservative; to make propionic acid; in plastic and rubber manufacturing; to make alkyl resins and plasticizers.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek med- ical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin res- cue breathing (using universal precautions, including resusci- tation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24?48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmo- nary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
[Fire Hazard]

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

UN1275 Propionaldehyde, Hazard Class: 3; Labels: 3-Flammable liquid.
[Incompatibilities]

Incompatible with strong acids; amines. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoa- cids, epoxides. Strong caustics; reducing agents can cause explosive polymerization. Can self-ignite if finely dispersed on porous or combustible material, such as fabric. Heat or UV light can cause decomposition. Aldehydes are fre- quently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are gener- ated by the combination of aldehydes with azo, diazo com- pounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (anti- oxidants) to shipments of aldehydes retards autoxidation
