(CH3) 2S + KMnO4 ~> MnIV + various oxidation products
Many organic compounds with C=C double bonds are indicated as well, but with different sensitivities. It is impossible to differentiate between them. H2S (hydrogen sulfide) is indicated with approximately twice the sensitivity. The tube H2S 5/b can be used as a filtering tube. Then, with n = 20 pump strokes approx. 30 ppm H2S is retained. Methyl mercaptan is indicated with approximately twice the sensitivity..
