As the zeolites exhibited effective catalytic activity to the methylation reaction of some aromatic amines
[16, 17, 22-24], several different zeolites such as H[beta], H-ZSM-5, NaX, NaY, and MCM-41 were chosen to catalyze the reaction of MDA with DMC in order to obtain MBDMA, as shown in Table 1.
Supernatants were run on HPLC to check the biodegradation of aromatic amine
Isolation of mutagenic aromatic amines
from coal conversion oil by cation exchange chromatography.
The stereospecificity due to the absence of aromatic amines
in common diuretics means they are safe for patients with known sulfa antibiotic allergies.
In some cases, the levels of aromatic amine
were 10 times above acceptable levels, it said.
Another important application of NAT2 genotyping is to study cancer risk related to exposure to aromatic amine
and heterocyclic amine carcinogens.

We know that we are not getting an aromatic amine
coming off, but we don't know if it is being bound or whether it's being metabolized and converted to something else."
To the best of our knowledge, no studies reported on the synthesis of hexasubstituted thiourea onto cyclotriphosphazene moieties bearing six units of amino acid or aromatic amines
. Our previous studies reported on thiourea bearing aromatic amine
with excellent antibacterial properties [6, 17].
Degradation of a 30 ppm solution of red dye 40 by the different types of bacteria used in this study showed evidence for the formation of analogous compounds to 1-naphthol and an aromatic amine
A mixture of 1-(2'-hydroxy-3'-iodo-5'-methylphenyl)-3-(2-hydroxy-4-methyl-5-chlorophenyl)-2-propen-1-one (0.01 mol) and substituted aromatic amine
(0.01 mol) was stirred at room temperature in water (20 mL) for an appropriate time (Table 1).
