DescriptionThe kinetics of the reactions of methylolphenols and urea were investigated using 2- and 4-hydroxybenzyl alcohols. The high-performance liquid chromatography (HPLC) using a reverse-phase column gave a clear separation between methylolphenols and hydroxybenzylureas. The molar ratios of hydroxybenzylureas to the corresponding methylolphenols in reaction mixtures were obtained from the ratios of peak areas of the chromatograms by using transfer factors corrected by quantitative 13C-NMR (carbon 13 nuclear magnetic resonance) measurements. The reactions of 2- and 4-hydroxybenzyl alcohols with excessive amounts of urea were found to follow the pseudo-first-order reaction.
