Overview
Cis-2-butene is an unsaturated hydrocarbon belonging to the alkene family. It is one of the isomers of butene, characterized by its double bond in the cis configuration. This compound is primarily used in industrial applications due to its reactivity and versatility. Cis-2-butene is commonly produced during petroleum refining and is a key intermediate in the synthesis of various chemicals. Its role in the production of synthetic rubber and plastics makes it a valuable commodity in the chemical industry.
Physical and Chemical Properties
Cis-2-butene is a colorless gas at room temperature with a faint, sweet odor. It has a boiling point of 3.7°C and a melting point of -138.9°C. The compound is highly flammable and reacts vigorously with oxidizing agents. The double bond in cis-2-butene makes it reactive, allowing it to participate in addition and polymerization reactions. Its insolubility in water but solubility in organic solvents like ethanol and acetone is notable for various industrial processes.
Main Applications
Cis-2-butene is widely used in the production of synthetic rubber, particularly butyl rubber, which is essential for manufacturing tires and other elastic products. It also serves as a precursor for plastics such as polyethylene and polypropylene. In addition, cis-2-butene is used as a chemical intermediate in the synthesis of other organic compounds, including alcohols, aldehydes, and ketones. Its role in petrochemical processes underscores its importance in industrial chemistry.
Safety and Storage
Due to its high flammability, cis-2-butene must be stored in a cool, well-ventilated area away from ignition sources. Proper grounding and bonding are essential to prevent static discharge during handling. Personal protective equipment (PPE) such as gloves, goggles, and flame-resistant clothing should be worn when working with this compound. In case of leakage, evacuate the area and use appropriate containment measures.
B2B Procurement Guide
When procuring cis-2-butene, it is crucial to verify the supplier's compliance with safety and quality standards. Bulk purchases may offer cost advantages, but ensure proper storage and transportation facilities are available. Request Material Safety Data Sheets (MSDS) and certificates of analysis to confirm purity and composition. Establish long-term relationships with reputable suppliers to ensure consistent quality and reliability.
