DMDS exhibits a range of well-defined physical and chemical characteristics that make it suitable for numerous applications. It typically presents as a colorless liquid. Key properties include a density of approximately 1.1 g/cm3, a boiling point of around 109.7 °C at 760 mmHg, and a low melting point of -85 °C. DMDS has a flash point of 24.4 °C, indicating its flammable nature, which necessitates careful handling and storage protocols. These precise specifications ensure its consistent performance in industrial processes.
The commitment to exceptional quality is paramount. Our Dimethyl Disulfide is produced to stringent standards, ensuring high purity. Our typical assay guarantees a purity of ≥99.0%, with some batches exceeding 99.5%. Rigorous analysis includes checks for sulfur content, methyl mercaptan content, methyl sulfide content, and moisture, all maintained within strict limits to ensure superior performance and safety. Every batch undergoes thorough testing to confirm it conforms to the highest factory standards, delivering a product you can trust.
The utility of Dimethyl Disulfide spans a remarkable array of industries.
In the petrochemical industry, DMDS serves as a critical sulfiding agent, particularly for catalyst pre-treatment in hydrodesulfurization (HDS) and hydrocracking units. It effectively converts metal oxides on catalyst surfaces into their more active sulfide forms, thereby enhancing their efficiency in removing sulfur and nitrogen compounds from petroleum streams. Furthermore, DMDS plays a role in controlling coke and carbon monoxide formation during various refining processes, contributing to optimized plant operations and extended catalyst lifespan.
Beyond petrochemicals, DMDS is a valuable component in the flavors and fragrances sector. Its characteristic odor, when highly diluted, contributes to the desirable profiles in certain food products, acting as a seasoning component. It is used to create specific aroma notes in a variety of foods and beverages, including certain cocoa, tea, and wine products.
DMDS also finds application in organic synthesis, serving as an important building block for the creation of various sulfur-containing organic compounds. Its reactive nature makes it a versatile reagent in the production of pesticides, pharmaceuticals, and other specialty chemicals. Additionally, it has been noted for use in dust control in steel rolling mills, showcasing its broad industrial applicability.
Given its highly flammable nature and classification as hazardous, proper handling and storage of Dimethyl Disulfide are crucial. It is highly volatile, and its vapors, being heavier than air, can form explosive mixtures. When heated or burned, it decomposes into corrosive and toxic vapors like hydrogen sulfide. Therefore, DMDS should always be stored in a cool, well-ventilated area, away from ignition sources and incompatible materials. Adherence to safety data sheet guidelines and local regulations is essential for safe operations. Packaging options typically include 200 kg drums, with flexibility for custom packaging solutions to meet specific customer requirements.
Dimethyl Disulfide (DMDS) is a chemical cornerstone with a profound impact across numerous industrial landscapes, from refining and chemical synthesis to the creation of flavors and fragrances. Its consistent purity and reliable performance are key to its widespread adoption.
