Reactive Group Datasheet

Ketones

What are reactive groups?

Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure. Each substance with a chemical datasheet has been assigned to one or more reactive groups, and CAMEO Chemicals uses the reactive group assignments to make its reactivity predictions. More Info...

If you can't find a chemical in the database--but you know what reactive group it belongs in--you can add the reactive group to MyChemicals instead in order to see the reactivity predictions.

There are 193 chemical datasheets assigned to this reactive group.

Description

Flammability

Many low-molecular-weight ketones (such as acetone and methyl ethyl ketone) are highly flammable. Most ketones are liquids with relatively high vapor pressures, capable of forming explosive mixtures with air.

Reactivity

Materials in this group 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.

Toxicity

Varies very widely. Some ketones are highly volatile and may have narcotic or anesthetic effects. Entry into the body occurs by absorption through the skin as well as inhalation and ingestion.

Other Characteristics

Compounds in this group are characterized by a carbonyl attached to two organic groups. These groups may be alkyl (paraffins) or aryl (aromatic). Reactions of this group are very similar in their behavior to that of aldehydes, because of their similar structure. These materials are generally used as solvents in the paint, textiles, plastics, and lacquer industries.

Examples

Acetone, acetophenone, cyclohexanone, diethylketone, diisobutylketone, dipropylketone, isophorone, methyl acetone, methyl amyl ketone, methyl butanone, methyl ethyl ketone.
