Description

Disulfides, Alkylaryl Dialkyl Diaryl, Petroleum Refinery Spent Caustic Oxidn. Products is a complex mixture of organic disulfide compounds derived from the oxidation of spent caustic streams in petroleum refining. This product serves as a valuable source of sulfur-containing intermediates and additives, offering a cost-effective and sustainable alternative to virgin materials. It is primarily utilized by industrial manufacturers in the lubricant, rubber, and specialty chemical sectors seeking performance-enhancing additives or chemical feedstocks.

Application

• Lubricant and Grease Additives: Acts as an extreme pressure (EP) and anti-wear agent, improving the performance of industrial and automotive lubricants under high-load conditions.
• Rubber Vulcanization and Processing: Functions as a vulcanizing agent or accelerator component in the production of various rubber goods, including tires and industrial rubber products.
• Chemical Intermediate: Serves as a feedstock for the synthesis of more complex sulfur-containing chemicals, such as sulfonates, mercaptans, and other specialty organosulfur compounds.
• Oilfield Chemicals: Used in formulations for drilling fluids and production chemicals where sulfur-based additives are required for corrosion inhibition or lubrication.
• Metalworking Fluids: Incorporated as an additive to provide lubricity and surface protection in cutting, grinding, and forming operations.
• Flotation Agents: May be employed in mineral processing as a component in froth flotation reagents for ore beneficiation.

Quality Control

Our production of Disulfides, Alkylaryl Dialkyl Diaryl, Petroleum Refinery Spent Caustic Oxidn. Products adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including sulfur content, viscosity, and flash point to ensure it meets the requirements of downstream industrial applications. Certificates of Analysis (COA) detailing specific batch characteristics are available upon request, providing transparency and traceability for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. This material is easily oxidized (store under inert atmosphere) and is compatible with strong alkali/organic solvent. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize oxidation and moisture pickup.
