Buta-1,3-diene

Buta-1,3-diene is a highly flammable organic compound with the molecular formula C4H6 and CAS number 106-99-0. This conjugated diene consists of four carbon atoms connected by alternating single and double bonds, making it a key building block in polymer chemistry. With a molecular weight of 54.09 g/mol, it exists as a colorless gas under normal conditions and is classified as extremely hazardous due to its carcinogenic and mutagenic properties.

Buta-1,3-diene is a colorless gas at room temperature with a characteristic mild aromatic odor. It has a boiling point of -4.4°C and a melting point of -108.9°C, making it gaseous under normal atmospheric conditions. The compound is slightly soluble in water but readily dissolves in organic solvents like alcohol and ether. It polymerizes easily and can form explosive peroxides when exposed to air and light.

Buta-1,3-diene is primarily used as a monomer in the production of synthetic rubber, particularly styrene-butadiene rubber (SBR) and polybutadiene rubber. It serves as a crucial raw material in manufacturing tires, footwear, and various rubber products. Additionally, it's employed in producing acrylonitrile-butadiene-styrene (ABS) plastics, latex paints, and as an intermediate in synthesizing other chemical compounds in the petrochemical industry.

Buta-1,3-diene requires extreme caution due to its carcinogenic properties and high flammability. Personnel must wear appropriate respiratory protection, chemical-resistant gloves, and protective clothing. Work areas must have adequate ventilation and explosion-proof equipment. Eliminate all ignition sources including static electricity, sparks, and hot surfaces. Use only in well-ventilated areas or fume hoods, and ensure emergency shower and eyewash stations are readily accessible.

Buta-1,3-diene must be stored in pressurized containers in cool, well-ventilated areas away from heat sources, sparks, and open flames. Storage areas should be equipped with explosion-proof electrical equipment and adequate fire suppression systems. Keep containers tightly sealed and protected from light to prevent polymerization. Store away from oxidizing agents and ensure proper grounding of equipment to prevent static electricity buildup.

Immediate evacuation from the exposure area to fresh air is essential in case of inhalation. Remove contaminated clothing and wash affected skin thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes. Seek immediate medical attention in all cases of exposure, emphasizing the carcinogenic nature of the substance to medical personnel. Do not induce vomiting if ingested.

Buta-1,3-diene disposal must comply with local and national hazardous waste regulations as it's classified as carcinogenic waste. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Never discharge into drains, waterways, or the environment. Small quantities may be allowed to evaporate in well-ventilated areas away from ignition sources, but only under controlled conditions and with proper authorization from environmental authorities.

Buta-1,3-diene is classified under ADR Class 2 (gases) for transportation purposes. It must be transported in appropriate pressure vessels designed for flammable gases, with proper labeling including GHS02, GHS04, and GHS08 pictograms. Vehicles must be equipped with appropriate fire extinguishers and emergency equipment. Transportation requires compliance with dangerous goods regulations, proper documentation, and trained personnel certified for hazardous materials transport.

Buta-1,3-diene is subject to strict regulations under REACH and CLP due to its classification as Carcinogenic 1A and Mutagenic 1B. It requires special handling procedures under occupational health and safety regulations, with mandatory exposure monitoring and health surveillance for workers. The substance is also regulated under various national chemical safety laws and may be subject to import/export licensing requirements in certain jurisdictions.
