Materials. Phthalic anhydride (PA), adipic acid (AA), neopentyl glycol (NPG), p-hydroxybenzoic acid (PHBA), salycilic acid, m-hydroxybenzoic acid (MHBA), xylene, and methyl isobutyl ketone (MIBK) were purchased from Aldrich. p-Toluenesulfonic acid (p-TSA) was purchased from Matheson. "Aromatic 150" solvent and "Resimene 7A6", a hexakis(methyloxymethyl)melamine (HMMM) resin were supplied by Exxon and Monsanto, respectively. "Bonderite 1000" pretreated cold-rolled steel panels 3"x9"x2AGA were purchased from Parker. 

The linear oligoester diol was heated with salycilic acid and with MHBA using a similar procedure to yield modified polyols. Only 60% to 80% of theoretical distillate was obtained. 

This beneficial effect was attributed to rate enhancements of reduction processes. With benzoic acid, total degradation of the ring to CO2 occurred and the detection of salycilic acid suggested the intervention of 0H° radicals (56). These radicals were also proposed to explain the oxidation of n-Cx alkanes (x = 6,7,9,10) and of cyclohexane in 1 1 vol. water ydrocarbon two-phase mixtures over 10 wt °l Pt/Ti02 Traces of alcohols (and of 2-, 4-, 5-decanone with decane) were detected. No transformation occurred without O2 and in the absence of H2O the rate was substantially decreased. The role of Pt was attributed to a greater ease of oxygen reduction however the oxidation rate was only decreased by a factor of about 1.5 without Pt (59). 

Well-defined organic compounds. Some of the relatively few organic molecules in seawater with a known structure have been examined for their binding ability with trace metals, e.g. amino acids (Simoes Goncalves et al., 1982, 1983 Valenta et al., 1984) and phtalic-, citric- and salycilic acid (Stumm and Brauner, 1975). 

Table 10. Contents of low molecular weight (LMP) and high molecular weight (HMP) phenolic derivatives in aerial parts of typical plant species from an exposed grassland slope of the northern Andes to 2100 m asl. LMP amounts are in mg equiv of salycilic acid g w/w and HMP are in mg equiv of quebracho tannin g w/w. Unusually large amounts may be due to differences in oxidation potential relative to the standard. Errors are one SD. Data from Alonso-Amelot et al. 2005.
