What is naphthylamine?

: either of two isomeric crystalline bases C10H9N used especially as dye intermediates.

How will you synthesize 1 naphthylamine from naphthalene?

Process for the preparation of 1-naphthylamine Abstract 1-Naphthylamine is prepared by the hydrogenation of 1-nitronophthalene which is virtually free of sulphur compounds and isomeric nitronaphthalenes, at elevated temperature and elevated pressure, in the presence of inert organic solvents miscible with water and in …

Where is 2-naphthylamine found?

2-Naphthylamine DNA adducts have been found in bladder and liver cells from exposed dogs (IARC 1987). 2-Naphthylamine is an aromatic amine (arylamine) that exists at room temperature as colorless crystals with a faint aromatic odor. It is soluble in hot water, alcohol, ether, and many organic solvents.

What is naphthylamine found in?

2-Naphthylamine is found in cigarette smoke and suspected to contribute to the development of bladder cancer. It is activated in the liver but quickly deactivated by conjugation to glucuronic acid. In the bladder, glucuronidase re-activates it by deconjugation, which leads to the development of bladder cancer.

Is 2-naphthylamine soluble in water?

2-naphthylamine is a naphthylamine carrying the amino group at position 2. It has a role as a carcinogenic agent. Beta-naphthylamine appears as a white to reddish colored solid in the form of flakes. Slightly soluble in hot water and denser than water.

Is 2-naphthylamine a carcinogen?

Exposures of workers are to be controlled through the required use of engineering controls, work practices, and personal protective equipment, including respirators. 2-Naphthylamine is listed in the NTP Report on Carcinogens as known to be a human carcinogen (NTP, 2005).

Is benzidine A?

What is benzidine? Benzidine is a manufactured chemical that does not occur in nature. In the past, large amounts of benzidine were used to produce dyes for cloth, paper, and leather. It was also used in clinical laboratories for detecting blood, as a rubber-compounding agent, and in the manufacture of plastic films.

Is 2 naphthylamine a carcinogen?

Is 2 naphthylamine soluble in water?

Is benzidine a toxic chemical?

No information is available on the acute (short-term) effects of benzidine in humans by inhalation exposure but benzidine is considered to be very acutely toxic to humans by ingestion. Chronic (long-term) exposure to benzidine in humans may result in injury to the bladder.

How is 2-naphthylamine soluble in hot water?

2-Naphthylamine is an aromatic amine (arylamine) that exists at room temperature as colorless crystals with a faint aromatic odor. It is soluble in hot water, alcohol, ether, and many organic solvents. 2-Naphthylamine oxidizes in the presence of air, and the vapors can be explosive (IARC 1974, Akron 2009).

Which is the most toxic form of naphthylamine?

CKR7XL41N4 Beta-naphthylamine appears as a white to reddish colored solid in the form of flakes. Slightly soluble in hot water and denser than water. Toxic by ingestion, inhalation and skin absorption. Used to make dyes and agricultural chemicals.

What does beta naphthylamine look like in water?

Beta-naphthylamine appears as a white to reddish colored solid in the form of flakes. Slightly soluble in hot water and denser than water. Toxic by ingestion, inhalation and skin absorption. Used to make dyes and agricultural chemicals.

What can N-phenyl-1-naphthylamine be used for?

N-Phenyl-1-naphthylamine’s production and use as an antioxidant in various lubrication oils and as both a protective agent and antioxidant in rubber and rubber mixtures for various products, including tires(1) may result in its release to the environment through various waste streams(SRC).
