In another case,l l PFA (with a melt flow rate of 4-9 g/lO-min) was first mixed with 0.1% by weight of a tin powder, 0.03% by weight of N-phenyl-a-naphthylamine, and 0.02% by weight of carbon black. This mixture was tumbled in a drum while being heated to a temperature of 304°C-310°C which lightened the color of the mixture. The cooled powder was loaded in the cavity of a carousel-type rotolining machine. Tin helped eliminate the bubbles from the part.

Stabilisers are usually determined by a time-consuming extraction from the polymer, followed by an IR or UV spectrophotometric measurement on the extract. Most stabilisers are complex aromatic compounds which exhibit intense UV absorption and therefore should show luminescence in many cases. The fluorescence emission spectra of Irgafos 168 and its phosphate degradation product, recorded in hexane at an excitation wavelength of 270 nm, are not spectrally distinct. However, the fluorescence quantum yield of the phosphate greatly exceeds that of the phosphite and this difference may enable quantitation of the phosphate concentration [150]. The application of emission spectroscopy to additive analysis was illustrated for Nonox Cl (/V./V -di-/i-naphthyl-p-phcnylene-diamine) [149] with fluorescence ex/em peaks at 392/490 nm and phosphorescence ex/em at 382/516 nm. Parker and Barnes [151] have reported the use of fluorescence for the determination of V-phenyl-l-naphthylamine and N-phenyl-2-naphthylamine in extracted vulcanised rubber. While pine tar and other additives in the rubber seriously interfered with the absorption spectrophotometric method this was not the case with the fluoromet-ric method. 

A portion of the white film from each package was heated in TCB containing 0.1% w/v of N-phenyl-2-naphthylamine as an antioxidant. The portion of the white film not covered by the label was sampled for the "bad" package sample. The "good" packages had no label. The nominal polymer concentration in solution was 2 mg/mL. The samples were filtered hot through 0.5-pm pore size glass fiber filters. TCB is a non-solvent for PET. Therefore, only the PE and EVA layers were dissolved. The middle PE layer accounted for about 80% of the film thickness. PET and EVA were minor components of the film.

Most of the work on the inhibition of oxidative degradation of HTPB by incorporating anti-oxidants is in the form of patents or classified reports [225-227]. The use of N-phenyl-P-naphthylamine (PBNA) has been extensively studied [226, 228] for this purpose but it is reported to be a carcinogenic material and hence banned for use as a propellant ingredient in developed countries.

In the ketone method, the central carbon atom is derived from phosgene (qv). A diarylketone is prepared from phosgene and a tertiary arylamine and then condenses with another mole of a tertiary arylamine (same or different) in the presence of phosphorus oxychloride or zinc chloride. The dye is produced directly without an oxidation step. Thus, ethyl violet [2390-59-2], Cl Basic Violet 4 (15), is prepared from 4,4 -bis(diethylamino)benzophenone with diethylaniline in the presence of phosphorus oxychloride. This reaction is very useful for the preparation of unsymmetrical dyes. Condensation of 4,4,-bis(dimethylamino)benzophenone [90-94-8] (Michler s ketone) with N-phenyl- 1-naphthylamine gives the Victoria Blue B [2580-56-5], Cl Basic Blue 26, which is used for coloring paper and producing ballpoint pen pastes and inks.

A new colorimetric procedure has been developed for the quantitative measurement of atmospheric ozone. The specific, sensitive, and reproducible nonaqueous method utilizes the rate of color produced on ozonization of o-dichlorobenzene solutions of N-phenyl-2-naphthylamine. The color reaction conforms to Beer s law and has a practical sensitivity of 1.8 X 10 mg. of ozone. Oxygen and oxides of nitrogen, in concentrations greater than those normally occurring in the atmosphere, do not interfere with the chromogenic reaction.

Occupational exposure to compounds containing a 2NA nucleus can result in 2NA exposure if metabolic enzymes can degrade the material. For example, workers inhaling 30 mg N-phenyl-2-naphthylamine in 1 day excreted 3—4 pg 2NA in their urine over the next 24 h. This is the 2NA exposure equivalent of smoking 5 packs of cigarettes. 

Preparation. In the most satisfactory procedure, a solution of acetophenone in isopropanol was treated with a trace of acetic acid and exposed in an inverted flask to sunlight for several months. The resulting 2,3-diphenylbutane-2,3-diol (li 35 g.) was treated with about 20 mg. of N-phenyl- 8-naphthylamine (polymeriza-... 

In contrast to the diphenylamine derivatives, transformation of the nitrogen radical (XII) to a nitroxyl radical, N-0-, has not been observed. Due to the longer lifetime of the nitrogen-centred radical (XII) by resonance stabilisation, dimerisation and oligomerisation take place whilst maintaining the -NH- function. Indications have been found that the products of Reaction (4.37) may result from direct reaction of phenyl-a-naphthylamine with oxygen [27, 35]. 

It was speculated that the second step of over-oxidation to acid might take place via a free radical pathway, arising from the catalytic decomposition of the t-BuOOH. It was further thought that the use of a free radical inhibitor might reduce the extent of the acid formation and inqjrove the overall aldehyde selectivity. The use of free radical scavengers such as 2,6-di-ier/-butyl-4-methylphenol (Table 4, Run 24), the stable free-radical, TEMPO, (Run 25) or the amine type inhibitor, N-Phenyl -2-Naphthylamine (Run 26), did not show any improvement in the reaction selectivity towards the formation of the aldehyde. The lack of any significant reduction in the amoimts of ester formed when using these modifiers showed that both steps of aldehyde and acid formation most likely do not include the involvement of free radical intermediates.

Using 02 Anderson et al. showed that the two major phenolic metabolites of N-phenyl-2-naphthylamine produced by liver enzymes are likely to be derived via arene oxide intermediates. The mechanism by which bromo-benzene is converted to 4-bromocatechol in isolated rat hepatocytes was shown with 62 to proceed via dehydrogenation of a dihydrodiol intermediate rather than by two successive hydroxylation reactions of the substrate. Similar studies have been performed on chlorpromazine.
