chemical properties

clear colorless liquid

usage

suitable for use in the precipitation of nucleic acids.

general description

a clear colorless liquid with a characteristic vinous odor and pungent taste. flash point 55°f. density 6.5 lb / gal. vapors are heavier than air.

air & water reactions

highly flammable. soluble in water in all proportions.

reactivity profile

etanol reacts violently with acetyl chloride and acetyl bromide [rose, (1961); merck 11th ed., 1989]. mixtures with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. mixtures with concentrated hydrogen peroxide form powerful explosives. reacts readily with hypochlorous acid and with chlorine to give ethyl hypochlorite, which decomposes in the cold and explodes on exposure to sunlight or heat. base-catalysed reactions with isocyanates should be carried out in inert solvents. such reactions in the absence of solvents often occur with explosive violence [wischmeyer(1969)]. highly oxidized potassium metal was dropped into a dish of ethyl alcohol, an immediate explosion shattered the dish. potassium superoxide was considered the cause of the reaction [health and safety inf. 251(1967)]. etanol or metanol can ignite on contact with a platinum-black catalyst. (urben 1794).

health hazard

vapor: irritating to eyes, nose and throat. liquid: not harmful.

fire hazard

flammable. flashback along vapor trail may occur. vapor may explode if ignited in an enclosed area.
