Reactive Group Datasheet

Amines

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 938 chemical datasheets assigned to this reactive group.

Description

Flammability

Amines are generally high-boiling liquids or solids at room temperature and are not highly flammable. Methylamine is an exception, because it is a gas with a wide flammability range. Amines are combustible. The combustion of amines yields noxious NOx.

Reactivity

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.

Toxicity

Variable. Some are very poisonous; others are only slightly toxic. Many amines are skin irritants. Some amines are known sensitizers for small populations of humans and serve to cause chemically induced allergic reactions. The effects of such reactions can be dramatic at rather low concentrations.

Other Characteristics

Amines are organic compounds derived from ammonia (NH3) by the replacement of one or more of the three hydrogen atoms of NH3 with an organic group R. The R group may be either aromatic or aliphatic. Aromatic amines contain at least one aromatic R group; aliphatic amines contain all aliphatic groups. Many amines have unpleasantly fishy or putrid odors.

Examples

Methylamine, aniline, triethanolamine, hexamethylenetetramine, cyclohexylamine, xylidine, ethylaniline, pyridine, anisidine, diphenylamine, ethylenediamine.
