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 (4- niroaninline).
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.

Aromatic Amines. 2.
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].
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).
