Description

2,5-Furandione, Dihydro-, Monopolybutenyl Derivs. is a specialized class of succinic anhydride derivatives, where the succinic anhydride moiety is modified with polybutenyl groups. This chemical modification is crucial for imparting unique properties such as enhanced hydrophobicity, improved compatibility with hydrocarbon matrices, and specific reactivity profiles. It is primarily sought after by industrial chemists and formulators in the polymer and lubricant additive sectors. The compound, identified by CAS NO 67762-79-2, serves as a key intermediate for synthesizing performance-enhancing additives.

Application

• Lubricant Additives: Acts as a key intermediate in the synthesis of succinimide dispersants and ashless anti-wear agents for engine oils and industrial lubricants.
• Polymer Modification: Used as a functional monomer or grafting agent to introduce polar, reactive sites into polyolefins and other polymers, improving adhesion, dyeability, or compatibility.
• Corrosion Inhibitors: Serves as a precursor for manufacturing corrosion-inhibiting additives used in fuel and oil systems.
• Surfactants & Emulsifiers: The polybutenyl chain provides oleophilic character, making derivatives useful in formulating specialty surfactants for industrial applications.
• Adhesive & Sealant Formulations: Imparts tackifying and compatibility properties in hot-melt and pressure-sensitive adhesive systems.
• Fuel Additives: Utilized in the production of detergents and deposit control additives for gasoline and diesel fuels.

Quality Control

Our production of Polybutenyl Succinic Anhydride adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, saponification number, and polybutenyl molecular weight distribution are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing assay, viscosity, and color is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to hydrolysis and reduced reactivity. Keep away from strong bases and oxidizing agents.
