What are aromatic amines used for?
Aromatic amines have been used in the production of rubber and in cutting oils, as intermediates in azo dye manufacturing, and as pesticides and are well-established causes of bladder cancer and one of the first carcinogens to be associated with an occupational exposure (IARC 1987; Siemiatycki et al.
What is meant by aromatic amine?
An aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond NH2.
Is benzene an amine?
Phenylamine is a primary amine and contains the -NH2 group attached to a benzene ring. The old name for phenylamine is aniline, and you could also reasonably call it aminobenzene. Phenylamine is what it is most commonly for UK-based exam purposes.
What is an NH group called?
In organic chemistry, amines (/əˈmiːn, ˈæmiːn/, UK also /ˈeɪmiːn/) are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Inorganic derivatives of ammonia are also called amines, such as monochloramine (NClH2). The substituent -NH2 is called an amino group.
What is the color of amine?
Aromatic primary amines give a reddish brown color, while the secondary amines form characteristic green color. This color reaction is applied to the quantitative determination of small amounts (110 μg/5 ml or 20 μg/5ml) of aromatic secondary amines.
What is the difference between aliphatic amine and aromatic amine?
Aliphatic amines are the amine compounds in which Nitrogen is bonded to only alkyl groups, and aromatic amines are the amine compounds in which Nitrogen is bonded to at least one of the aryl groups. This structural difference leads to all other differences in their properties such as reactivity, acidity, and stability.
Is morpholine an amine?
dor, morpholine is what is volatile with in aqueous so Properties: Classified as a lower aliphatic secondary amine (Turcotte and Johnson, 1992). A mobile, hygroscopic liquid, with a characteristic amine odor, morpholine is miscible in water with the formation of some heat (Budavari, 1996).
What kind of compound is an aromatic amine?
Aromatic amine. An aromatic amine is an organic compound consisting of an aromatic ring attached to an amine.
What are the side effects of aromatic amines?
Anilines Aromatic amines can cause methaemoglobinemia, agranulocytosis, aplastic anaemia, hepatotoxicity, skin hypersensitivity and increased risk of mutagenicity. There are two principal mechanisms of aniline toxicity. The first is oxidation of the aromatic ring ortho or para to the aniline nitrogen as in Scheme 1.15.
Why are aromatic amines used in dyeing industry?
Aromatic amines are amines with nitrogen atom which is linked to an aromatic ring. The alkalinity of amine is decreased due to the aromatic ring and depends on its substituents. Aromatic amines are widely used in dyeing industry as a starting material for manufacturing of different types of azo dyes, such as methyl orange,…
What foods have high levels of aromatic amines?
And, those who liked their meat or fish charred had the highest levels of heterocyclic aromatic amines (HAAs), chemicals that affect the inner lining of blood vessels and have been associated with atherosclerosis, which causes arteries to narrow and is a primary cause of heart disease. Primary aromatic amines (PAAs) are food contaminants.
