In the complex world of petrochemicals, efficiency and reliability are paramount. For oil refineries, a critical component in achieving these goals is the effective use of sulfiding agents. Among these, Dimethyl Disulfide (DMDS) stands out for its efficacy and specific chemical properties. As a leading manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-purity DMDS to meet the demanding standards of the industry.

What is Dimethyl Disulfide (DMDS)?

Dimethyl Disulfide, commonly known as DMDS, is an organosulfur compound with the chemical formula CH3SSCH3. It is a colorless liquid with a distinct, pungent, garlic-like odor. Its chemical structure, featuring a sulfur-sulfur bond, makes it highly reactive and suitable for specific industrial processes. With a purity of 99.9%, our DMDS offers superior performance for your critical operations.

The Role of DMDS in Oil Refineries

One of the primary industrial applications for DMDS is its use as a sulfiding agent in oil refineries. Refineries utilize catalysts, such as those containing molybdenum or cobalt-molybdenum, to remove sulfur compounds from crude oil during processes like hydrodesulfurization (HDS) and hydrocracking. These catalysts are often supplied in their oxide form and must be converted to their active sulfide form before they can function effectively. DMDS is an excellent precursor for generating hydrogen sulfide (H2S) in situ at elevated temperatures, which then converts the metal oxides into metal sulfides. This process is crucial for the efficient operation of the refinery and for meeting environmental regulations concerning sulfur emissions.
