The hydroxyphenylbenzotriazole structure was constructed by a coupling of the diazonium salt of o-nitroaniline with 4-ethyl-phenol, followed by reduction of the nitro-azobenzene to the benzotriazole with zinc powder and NaOH. After blocking of the phenol by acetylation, bromination and dehydrobromination were performed as described earlier, and treatment with aqueous NaOH...

Figure 11, Time on stream dependence of (a) phenol conversion and 2-ethyl phenol selectivity and (b) 2-ethyl phenol yield at 3750C on Cul -xCoxFe204 (x = 0.0, 0.5 and 1.0). Reactant feed ratio of EtOFI PhOH = 5 1 was used with a WHSV = 0.869 h-1. Conversion and selectivity is denoted by open and solid symbols, respectively. Note an increase in 2-ethyl phenol selectivity with increasing TOS on all catalyst compositions.

A special type of polymeric antioxidant is anoxomer, which consists of 1,4-benzenediol, 2-(l,l-dimethylethyl)-polymer with diethylbenzene, 4-(l,l-dimethyl-ethyl)phenol, 4-methoxy-phenol, 4,4 -(l-methylethylidene)bis(phenol), and 4-methylphenol prepared by condensation polymerization of divinylbenzene (m- and p-) with tert-butylhydroquinone, tert-butylphenol, hy-droxyanisole, p-cresol, and 4,4 -isopropylidenediphenol. Total monomers, dimers, and trimers below 500 are not more than 1%. Anoxomer is permitted in the United States as an antioxidant in food at a level of not more than 5 ppm of fat and oil content of the food.

Oil-containing adhesives might emit fatty acid oxidation products like saturated and unsaturated aldehydes which can contribute to odor (Wilke, Jann and Brodner, 2004). Adhesives on a phenol resin base have been found responsible for odor annoyance in several office buildings in former East Berlin. Alkyl-substituted phenols, methyl, dimethyl and ethyl phenols, some of which have very low odor thresholds, have been detected in indoor air as well as in different floor samples and were most likely responsible for the off-odor (Kirchner and Pernak, 2004). 

The conditions vary from case to case and need to be optimized accordingly. Solution-phase synthesized ligands are characterized by H-NMR, 13C-NMR, and mass spectroscopy, and further immobilized on a solid support (see Note 9 or step 7c). As an example, we describe the solution-phase synthesis of ApA, 4-[2-(4-chloro-6-phenylamino-[l,3,5]-triazin-2-ylamino)-ethyl]-phenol (Fig. 2B).

The mass spectrum of ethyl phenol, a typical phenol, is shown in Figure 1.19. This spectrum shows that a methyl group is lost much more readily than an a-hydrogen.
