发明名称 Dimethyl disulphide based composition with masked odour and method of obtaining same
摘要 The normal strong aggressive odor of dimethyldisulfide is reduced by limiting the content of methylmercaptan to less than 500 ppm and of dimethylsulfide to less than 100 ppm, and incorporating up to 1 % of at least one odor masking agent. A composition based on dimethyldisulfide CH3SSCH3 (DMDS) containing (by wt.) at least 95 % DMDS, less than 500 ppm (preferably less than 200 ppm) methylmercaptan, less than 100 ppm (preferably less than 50 ppm) dimethylsulfide and up to 1 % ( preferably 0.1-0.5 % and especially about 0.2 %) of at least one odor masking agent.
