Description

2-Butene is a versatile, highly reactive hydrocarbon gas that serves as a fundamental building block in industrial organic synthesis. Its value lies in its role as a key intermediate for producing a wide range of higher-value chemicals and polymers, offering manufacturers a critical raw material for scalable processes. This product is essential for industries including petrochemicals, polymer manufacturing, and specialty chemical synthesis, where its distinct isomeric forms (cis- and trans-) provide specific reactivity profiles.

Application

• Polymer Production: A crucial monomer and comonomer in the manufacture of polyethylene, polybutene, and other polyolefins.
• Chemical Intermediate: Used in the synthesis of important derivatives such as butylene oxide, sec-butanol, and methyl ethyl ketone (MEK).
• Alkylation Feedstock: Employed in refinery alkylation processes to produce high-octane gasoline blending components.
• Fuel & Fuel Additives: Acts as a component in liquefied petroleum gas (LPG) and as a precursor for oxygenated fuel additives.
• Solvent Manufacturing: Serves as a starting material for the production of various industrial solvents.
• Research & Development: Utilized in laboratories for organic synthesis, catalysis studies, and material science research.

Quality Control

Our 2-Butene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) detailing purity, isomer composition, and impurity profiles. Our quality systems are designed to meet the rigorous demands of industrial-scale chemical manufacturing and supply chain integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and gaseous nature, containers must be kept tightly sealed and upright to prevent leakage. Store away from strong oxidizing agents. Cylinders should be secured to prevent falling or damage.
