| Abstract |
Formaldehyde emitted during heat treatment of phenolic resin containing hexamethylenetetramine was measured by colorimetric methods using the following reaction agents: sulfite-pararosaniline, MBHT (3-methyl-2-benzothiazolone-hydrazone-hydrochloride), AHMT (4-amino-3-hydrazino-5-mercapto-1,2,4-triazole) and acetylacetone. The stain tube for formaldehyde was tested as well. Interferences by hexamethylenetetramine occurred with all reagents excepting AHMT. |
