1,3-Butadiene, a fundamental petrochemical with the chemical formula C4H6 and CAS number 106-99-0, is renowned for its role as a precursor to high-performance polymers and synthetic rubbers. Understanding its unique chemical and physical properties is essential for researchers, formulators, and procurement specialists who work with this versatile compound. As a colorless gas at standard conditions, its handling and application require specific knowledge.

The defining characteristic of 1,3-Butadiene is its conjugated diene structure, featuring two double bonds separated by a single bond (H₂C=CH−CH=CH₂). This conjugation imparts significant reactivity, particularly in addition reactions and polymerization. It readily undergoes Diels-Alder reactions, a cornerstone of organic synthesis for forming cyclic compounds, and is a prime monomer for chain-growth polymerization to create long polymer chains. For manufacturers seeking to buy 1,3-butadiene for these purposes, consistent purity is key.

Physically, 1,3-Butadiene is a highly flammable gas with a boiling point of approximately -4.4°C. This low boiling point means it is typically handled and transported as a liquefied gas under pressure. Its vapors are heavier than air, posing a risk of accumulation in low-lying areas and potential flashback ignition. Consequently, safety considerations are paramount when dealing with this chemical. Reputable suppliers, such as those offering C4H6 gas for sale, provide detailed safety data sheets (SDS) outlining all necessary precautions.

The industrial applications of 1,3-Butadiene are diverse, primarily driven by its polymerization capabilities. It is the essential monomer for producing styrene-butadiene rubber (SBR) and polybutadiene rubber (BR), materials vital for the automotive industry, particularly for tire manufacturing. Additionally, it's used in the synthesis of acrylonitrile-butadiene-styrene (ABS) resins, known for their impact resistance, and in the production of adiponitrile, a key intermediate for nylon. Accessing this chemical from a reliable synthetic rubber monomer manufacturer ensures the quality needed for these processes.

For those looking to procure 1,3-Butadiene, understanding its specifications, such as industrial grade purity (often 99.5%), and the best practices for storage and handling is critical. Whether you are a researcher exploring new polymer formulations or a procurement manager sourcing raw materials, a comprehensive grasp of the 1,3-butadiene chemical properties will facilitate informed decisions and ensure successful application. Partnering with experienced suppliers, particularly those in China known for their petrochemical output, can provide both quality products and valuable technical support.
