| | 2-ETHYLBUTYRALDEHYDE Usage And Synthesis |
| Chemical Properties | Colorless liquid.Insoluble in water. | | Chemical Properties | Ethyl butyraldehyde is a colorless liquid | | Chemical Properties | 2-Ethylbutyraldehyde has a pungent odor. | | Occurrence | Reported found in melon, French fried potato, wheaten bread, scallops, citrus fruits, white bread and maize. | | Uses | 2-Ethylbutyraldehyde has been used in the preparation of aldoximes using aqueous hydroxylamine. | | Uses | Organic synthesis, pharmaceuticals, rubber
accelerators, synthetic resins. | | Definition | ChEBI: 2-Ethylbutanal is an organooxygen compound. | | Taste threshold values | Taste characteristics at 20 ppm: green, fruity, cocoa with sweet, fresh nuances. | | General Description | A clear colorless liquid. Flash point 70°F. Less dense than water and insoluble in water. Vapors heavier than air. | | Air & Water Reactions | Highly flammable. With air slowly form peroxides. Insoluble in water. | | Reactivity Profile | 2-ETHYLBUTYRALDEHYDE is an aldehyde. Aldehydes are frequently 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 generated by the combination of aldehydes with azo, diazo compounds, 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 (antioxidants) to shipments of aldehydes retards autoxidation. | | Hazard | Irritant to eyes and skin. Flammable, dangerous fire risk. | | Health Hazard | May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | | Fire Hazard | HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | | Safety Profile | Moderately toxic by
ingestion. Mildly toxic by inhalation. A skin
irritant. Flammable liquid. Can react
vigorously with oxidizing materials. To fight
fire, use alcohol foam, Co2, dry chemical.
When heated to decomposition it emits
acrid smoke and fumes. See also
ALDEHYDES. | | Synthesis | From diethyl carbinol and anhydrous oxalic acid or with sulfuric acid; a more recent synthetic route (Xeisel–Neuwirth
method) calls for the reduction of α-vinylcrotonaldehyde using iron dust and acetic acid | | Potential Exposure | Used in organic synthesis of pharmaceuticals and rubber chemicals. | | Shipping | UN1178 2-Ethyl butyraldehyde, Hazard Class: 3;
Labels: 3-Flammable liquid | | Incompatibilities | Vapors may form explosive mixture with
air. 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,
oxoacids, epoxides, and reducing agents. Aldehydes are frequently involved in self-condensation or polymerization

with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed. Consult with environmental regulatory agencies
for guidance on acceptable disposal practices. Generators
of waste containing this contaminant (≥100 kg/mo) must
conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
