111-71-7 Usage

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.

Air & Water Reactions

Flammable. Insoluble in water.

General Description

A colorless, oily liquid with a penetrating fruity odor. Insoluble in water and less dense than water. Hence floats on water. Flash point near 141°F. Used to make perfumes and pharmaceuticals.

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.

Uses

Manufacture of 1-heptanol; ethyl oenanthate.

Uses

Labelled Heptanal. Bioconversion of heptanal to heptanol by Saccharomyces cerevisiae and effect of C source maltose.

Reactivity Profile

Heptaldehyde may undergo exothermic self-condensation or polymerization reactions in the presence of acids. May generate flammable and/or toxic gases with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Is readily oxidized to give heptanoic acid. Can react with air to give first peroxo acids, and ultimately heptanoic acid. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The presence of stabilizers (antioxidants) retards autoxidation. Incompatible with strong oxidizers, bases and reducing agents.

Chemical Properties

colourless liquid

Purification Methods

Dry n-heptaldehyde with CaSO4 or Na2SO4 and fractionally distil it under reduced pressure. More extensive purification is by precipitation as the bisulfite compound (formed by adding the aldehyde to saturated aqueous NaHSO3) which is filtered off and recrystallised from hot H2O. The crystals, after being filtered and washed well with H2O, are hydrolysed by adding 700mL of aqueous Na2CO3 (12.5% w/w of anhydrous Na2CO3) per 100g of aldehyde. The aldehyde is then steam distilled off, separated, dried with CuSO4 and distilled under reduced pressure in a slow stream of nitrogen.
