| Description | l DMDS is a thiomethylation agent used for organic synthesis.
l It is the most widely used sulphur compound as presulfiding agent for hydrodesulfurization, hydrotreatment and hydrocracking catalysts in oil refineries. l DMDS is added to sweet steam cracker feedstocks to reduce coke, prevent CO formation and tube corrosion, and thus increase run length of furnaces. l DMDS has been registered for use by many countries as a preplant soil fumigant with activity against nematodes, weeds and soil pathogens for a number of crops, DMDS is also approved as a food flavouring agent. |
