Abstract
We have studied dimethyl disulfide conversion on heterogeneous catalys ts in a flow setup at T=250-350 degrees C and atmospheric pressure. Me thyl mercaptan appears to be the main reaction product. The rate of di methyl disulfide decomposition and its selectivity towards methyl merc aptan in H2S medium are higher than those in pure helium. Thus the pro cess seems to involve the surface protons formed upon dissociative H2S chemisorption.
