Determination of 3,3′-dichloro-4,4′-diaminodiphenylmethane in air

Spectrophotometric determination of amines with p-chloranil

“…However, as with p-chloranil, neither of these reagents can be used to determine tertiary amines, and neither are suited for determining amines in nonaqueous solvents. Both fluorescamine and o-phthalaldehyde were recommended along with Ehrlich's reagent (23) (p-dimethylaminobenzaldehyde), ethyl Ehrlich's reagent (24), p-dimethylaminocinnamaldehyde (23,25), and p-chloranil as possible reagents for detecting small amounts of primary amines on solid surfaces (26). In addition, H-acid (9-amino-1hydroxynaphthalene-3,6-disulfonic acid) and N-na (N-[lnaphthalenyl) -1,2-ethanediamine) are useful colorimetric reagents for determining a variety of primary and secondary amines (27).…”

Detection limits of chemical spot tests toward certain carcinogens on metal, painted, and concrete surfaces

“…After methanol has evaporated from the paper, lift paper from surface and by using a suitable dropper, streak visualization reagent across the paper. 4. Examine after suitable time period.…”

“…1. Ehrlich's reagent (3) (p -dimethylaminobenzaldehyde) or ethyl Ehrlich's reagent (4) (p-diethylaminobenzaldehyde) with primary amines.…”

“…Chloranil (6) (tetrachloro-l,4-benzoquinone) with primary aryl amines. 4. Fluorescamine (Fluram), (7-10) 4-phenylspiro(furan-2[3//]l/-phthalan)-3,3'-dione with primary amines.…”

Determination of several industrial aromatic amines in fish

“…Many workers have published detection schemes for various aromatic amines, using gas-liquid, high performance liquid, or thin-layer chromatography, sometimes coupled with ancillary techniques such as ultraviolet or fluorescence spectrometry (3)(4)(5)(6)(7)(8)(9)(10)(11)(12). Most investigations into amines in fish or foods have centered around naturally derived volatile amines such as diand trimethylamine, or more recently the N-nitrosamines (13-16).…”
