2,2-dimethylpropane

2,2-dimethylpropane is a branched alkane hydrocarbon with the molecular formula C5H12 and CAS number 463-82-1. Also known as neopentane, it consists of a central carbon atom bonded to four methyl groups, creating a highly symmetrical structure. With a molecular weight of 72.15 g/mol, this compound is classified as a flammable gas under pressure and poses potential environmental hazards to aquatic life with long-lasting effects.

2,2-dimethylpropane is a colorless gas at room temperature with a faint gasoline-like odor. It has a boiling point of 9.5°C and melting point of -16.6°C, making it volatile under normal conditions. The compound is practically insoluble in water but readily soluble in organic solvents like alcohols and ethers. Its highly branched structure gives it lower density and different reactivity compared to linear pentane isomers.

2,2-dimethylpropane serves primarily as a specialty solvent and chemical intermediate in organic synthesis. It is used in the production of high-octane fuels due to its excellent anti-knock properties. The compound also finds applications in refrigeration systems, as a blowing agent for foam production, and in the manufacture of specialty chemicals. Its unique branched structure makes it valuable for research purposes and niche industrial applications.

2,2-dimethylpropane requires careful handling due to its flammable gas classification and pressurized state. Use appropriate personal protective equipment including safety goggles, protective gloves, and flame-resistant clothing. Ensure adequate ventilation and eliminate all ignition sources in the work area. Handle containers with care to prevent pressure release, and use proper gas handling equipment. Work in well-ventilated areas or under fume hoods to prevent vapor accumulation.

2,2-dimethylpropane must be stored in pressurized containers designed for flammable gases, away from heat sources, sparks, and open flames. Storage areas should be well-ventilated, cool, and dry with temperatures below 50°C. Keep containers upright and secure to prevent falling or damage. Store away from oxidizing agents and incompatible materials. Ensure proper grounding of equipment and containers to prevent static electricity buildup during handling.

In case of inhalation of 2,2-dimethylpropane, immediately move the affected person to fresh air and keep them at rest. If skin contact occurs, remove contaminated clothing and wash affected areas with plenty of water. For eye contact, rinse thoroughly with water for at least 15 minutes. Seek immediate medical attention if symptoms persist or if large amounts were inhaled. Do not induce vomiting if ingestion occurs.

2,2-dimethylpropane waste must be disposed of according to local, national, and EU waste regulations as a hazardous flammable gas waste. Contact authorized hazardous waste disposal companies for proper collection and treatment. Do not release into the environment due to its aquatic toxicity classification. Empty containers should be depressurized safely and disposed of according to metal waste regulations. Ensure complete documentation of waste disposal for regulatory compliance.

2,2-dimethylpropane is classified under ADR Class 2 as a flammable gas for transport purposes. It must be shipped in approved pressure vessels designed for gas transport, properly labeled with appropriate hazard placards and documentation. Transport vehicles must comply with ADR regulations for flammable gases, including proper ventilation and emergency equipment. Only trained personnel should handle transportation, and specific routing restrictions may apply in populated areas.

2,2-dimethylpropane is regulated under EU CLP regulation with hazard classes including Flammable Gas 1, Pressurized Gas, and Aquatic Chronic 2, requiring 'Danger' signal word and specific pictograms. It is not classified as a SVHC substance under REACH. Users must comply with occupational exposure limits, environmental discharge restrictions, and proper classification/labeling requirements. Industrial users may need to register quantities and maintain safety data sheets.
