Abstract
Since the determination of mono-and bis-(hydroxymethyl)-urea in an initial reaction product byuse of infrared absorption spectra was difficult when hexamethylenetetramine is used as a catalyst, hexamethylenetetramine was removed by extraction with chloroform and used for quantitative determination by use of infrared absorption spectra with the standard deviation of 2%. Quantitative determination of hexamethylenetetramine in various kinds of initial reaction products is made by this method and clarified that nearly all hexamethylenetetramine remain unchanged during the initialreaction period.
