According to Dr Sam Chang of Nashville, Tennessee’s Vanderbilt-Ingram Cancer Center, 92% of vapers tested positive for o-toluidine and 2-naphthylamine, two chemicals which have been linked to bladder cancer.
Smokers excreted similar amounts of 4-aminobiphenyl (78.6 ± 85.2 ng/24 h) as non-smokers (68.1 ± 91.5 ng/24 h), and similar amounts of 2-naphthylamine (84.5 ± 102.7 ng/24 h) as non-smokers (120.8 ± 279.2) (95).
While some agents such as asbestos, benzene and heavy metals are currently widely used in many countries, other agents have mainly an historical interest (e.g., mustard gas and 2-naphthylamine).

Process technology is described for producing a reaction-derived product mixture containing a high yield of octylated phenyl-alpha-naphthylamine by catalytic alkylation of phenyl-alpha-naphthylamine with diisobutylene.
The antioxidant (C) is selected from the group consisting of a sulfur containing phenolic antioxidant, a phenyl-alpha-naphthylamine antioxidant, and combinations thereof.
Lack of a red color in the medium after the addition of sulfanilic acid and alpha-naphthylamine means only that nitrite is not present in the medium.
When alpha-naphthylamine (Nitrate reagent B) is added to the incubated medium, a red precipitate (prontosil) will be formed with any nitrite-sulfanilic acid complex present in the medium.
This complex will then yield a red precipitate (prontosil) when nitrate reagent B (alpha-naphthylamine) is then added to the test as shown in Figure 2.
This enamine compound is from most inexpensive and readily available asymmetric secondary naphthylamine.
The mole ratio of diphenylamine:N-aryl naphthylamine is from 1:1 to 10:1.
The enamine eliminates sodium bisulfite with formation of naphthylamine 6.
The resultant product composition comprises diphenylamine homooligomers and diphenylamine/N-aryl naphthylamine cross oligomers.
The enamine eliminates sodium bisulfite with formation of napthylamine 6.
Beta-naphthylamine and benzidine are substances that can cause malignant tumors.
The diphenylamine and N-aryl naphthylamine are desirably substituted with alkyl groups having from 1 to 20 carbon atoms or styryl groups.
An antioxidant stabilizer composition is disclosed that is the reaction product of a diphenylamine and an N-aryl naphthylamine in the presence of an organic peroxide.
A lubricating oil composition comprising, blended into a base oil, (A) an ester phosphate, (B) an ester thiophosphate, and (C) a naphthylamine derivative.
The reaction takes place in the presence of oxygen to form an antioxidant comprising oligomers of the alkylated diphenylamine and the alkylated phenyl-α-naphthyl amine, and a metal component of the catalyst.

The Bucherer reaction in organic chemistry is the reversible conversion of a naphthol to a naphthylamine in the presence of ammonia and sodium bisulfite.[1][2][3][4][5]
Industrial chemicals, such as benzidine and beta-naphthylamine, compounds known as arylamines, at even a low fluid consumption have been associated with bladder cancer.
