Thin layer chromatogram of reaction mixtures of 7 different herbicides with Br-Mmc. Each sample contains 8 μg in 100 mm3 acetone, 1 mm3/spot was applied with a micropipette. 0 = blank, 1. 2,4-dichlorophenoxyacetic acid, 2. 4-(4-chloro-o-tolyoxy)-butyric acid (MCPB), 3. 1-naphthylacetic acid, 4. 4-chloro-o-tolyoxyacetic acid (MCPA), 5. 2-(2,4-dichlorophenoxy)-propionic acid, 6. 2,4,5-trichlorophenoxyacetic acid, 7. 3,6-dichloro-o-anisic acid (Dicamba). A = Br-Mmc, B = byproducts
(* instead of benzene we recommend the less toxic toluene)
