2-Butanone Chemical Properties,Uses,Production

Description

2-Butanone is a stable, highly flammable chemical. It is incompatible with oxidising agents, bases, and strong reducing agents. It is a colourless liquid with a sharp, sweet odour. 2-Butanone is produced in large quantities. It is used as a solvent and nearly half of its use is in paints and other coatings because it will quickly evaporate into the air and it dissolves many substances. It is also used in glues and as a cleaning agent.

Chemical Properties

colourless liquid

Uses

2-Butanone is an eye irritant that has been used as a water soluble photoinitiator for the photopolymerization of methacrylic acid (MAA).

Definition

ChEBI: A dialkyl ketone that is a four-carbon ketone carrying a single keto- group at position C-2.

Uses

As solvent; in the surface coating industry; manufacture of smokeless powder; colorless synthetic resins.

General Description

Methyl ethyl ketone (MEK) is a colourless liquid with a sweet and sharp odour. It is soluble in alcohol, ether, acetone benzene, and water. It is a solvent often found in mixtures with acetone, ethyl acetate, n-hexane, toluene, or alcohols. It has applications in the surface coating industry and in the de-waxing of lubricating oils. MEK is used in the manufacture of colourless synthetic resins, artificial leather, rubbers, lacquers, varnishes, and glues.

Air & Water Reactions

Highly flammable. Slightly soluble in water.

Reactivity Profile

Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

Health Hazard

May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to 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

Flammable/combustible material. May be 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.
