Polymer-type antioxidants have been prepared by Eriedel-Crafts reaction of -cresol andp- and/or y -chloromethylstyrene in the presence of boron trifluoride-etherate (198). The oligomeric product resulting from the alkylation of phenyl-a-naphthylamine using C12—15 propylene oligomer in the presence of AlCl or activated white clays is used as an antioxidant additive for lubricating oils (199).

Recently, trans insertion of hexafluorobutyne into one of the M—H bonds in some metallocene hydrides, Cp2MH , was studied in some detail (47). Experiments carried out in the presence of various radical-sensitive reagents such as TV-phenyl-a-naphthylamine suggested that a free radical mechanism was unlikely. A stepwise ionic mechanism, involving a zwitter-ionic intermediate, Cp2(H2)M+—C(CF3)==CCF3, is improbable, since (i) the stereochemistry and the apparent rate are not influenced by the polarity of the solvents, (ii) no deuterium is incorporated in the reaction in EtOD, and (iii) the trend in reactivity (Mo > W) does not reflect the trend in v-basicity or M—C bond stability (W > Mo). An essentially concerted trans-insertion mechanism is inferred, which is supported inter alia by the low kinetic deuterium isotope effect (kH/k0 = 1).

It has been demonstrated that the nitroxyl radical, X, reacts with a secondary alkyl radical to form XI which, under high-temperature conditions (>120°C), regenerates the original diphenylamine molecule, Reaction (4.36). In essence, this group of stabilisers acts catalytically by scavenging alternately peroxy (ROO-) and alkyl radicals (R-). As stated earlier, sterically hindered phenols deactivate only two peroxy radicals per phenol molecule. Hence, under high-temperature conditions, aromatic amines are far superior to their phenolic counterparts. As shown in Table 4.3, the stoichiometric factor of the diphenylamines depends on the substituents in the para position [33]. The efficacy of the diphenylamine antioxidant is improved by alkylating the para positions. The stabilisation mechanism for phenyl-a-naphthylamines. Reaction sequence (4.37) [34], is described as follows ... 

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]. 

Anti-oxidants, AOs, for ester-based turbine lubricants are of the hindered amine type, as described in Chapter 4. Commonly used anti-oxidants are phenyl-a-naphthylamine, PAN, octylphenyl-a-naphthylamine, ORAN, and dioctyldipheny-lamine, DODPA, and derivatives thereof. Phenothiazine was a common anti-oxidant in the early years of ester-based turbine lubricants but although effective it formed particulates when the lubricant became oxidised. Since particulate formation is a major limiting factor for an engine manufacturer the use of phenothiazine stopped. Phenyl-P-naphthylamine was also used in early lubricants but its use was subsequently banned when it was found to be harmful.

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.
