Properties and Usage:
Dimethyl disulfide (DMDS for short) is a volatile liquid with a strong sulfur odor and good chemical stability. It is mainly used in the fields of synthetic chemicals, agricultural soil treatment, oil and natural gas desulfurization, and environmental protection.
1.Chemical raw materials and intermediates
Synthetic chemicals: DMDS is used to produce a variety of sulfur-containing compounds, such as pesticides and pharmaceutical intermediates. These compounds have clear uses in agriculture, medicine and other industrial fields, such as pesticides, pharmaceutical raw materials, etc.
Catalyst: In some catalytic reactions, DMDS can be used as a catalyst or co-catalyst, especially during the synthesis and reaction of sulfides, which can significantly improve reaction efficiency and ensure high selectivity and precision of the reaction.
2. Agriculture
Soil Fumigants: DMDS is widely used in soil fumigation to eliminate pathogens, weeds and pests in the soil. This not only improves soil quality, but also significantly increases crop yields and improves the agricultural production environment.
3. Oil and gas industry
Desulfurizer: In the refining process of oil and natural gas, DMDS is used as a desulfurization agent to remove sulfides in oil and gas, thereby reducing environmental pollution and improving product quality.
Hydrogen Sulfide Capture: DMDS is also used in gas processing to capture and remove hydrogen sulfide, helping to prevent the impact of corrosive gases on equipment and the environment.
4.Environmental protection
Wastewater treatment: In wastewater treatment, DMDS, as an effective desulfurization reagent, can help remove sulfide pollutants in wastewater, reduce the pollution load of wastewater, improve water quality, and protect the water environment.
5. Food and spice industry
Odor Modulation: Due to its unique odor, DMDS is used in the food and flavor industries to modulate odor and enhance or modify the flavor profile of products.
Storage conditions: Store in a cool and dry place, away from direct sunlight and water, and keep away from oxidants and acids
Packing: This product is packed in 25kg 100kg drums, and it can also be customized according to customers' requirements
