2-methylpropane

2-methylpropane is a branched alkane hydrocarbon with the molecular formula C4H10 and CAS number 75-28-5. Also known as isobutane, it is a colorless, flammable gas at room temperature with a molecular weight of 58.12 g/mol. This saturated hydrocarbon belongs to the butane isomer family and is classified as a highly flammable gas under GHS regulations, requiring careful handling and storage procedures.

2-methylpropane is a colorless gas at room temperature and atmospheric pressure with a faint petroleum-like odor. It has a boiling point of -11.7°C and a melting point of -159.6°C. The substance is practically insoluble in water but readily soluble in organic solvents. As a pressurized gas, it can be liquefied under pressure and has a density lower than water when in liquid form.

2-methylpropane serves primarily as a refrigerant in commercial and domestic refrigeration systems, replacing ozone-depleting substances. It is widely used as a propellant in aerosol products including cosmetics, pharmaceuticals, and household sprays. Additionally, it functions as a fuel component in portable gas cartridges for camping equipment and as a feedstock in petrochemical processes for producing other chemical compounds and polymers.

2-methylpropane requires strict safety measures due to its flammable gas classification. Always use appropriate personal protective equipment including safety glasses, protective gloves, and flame-resistant clothing. Ensure adequate ventilation and eliminate all ignition sources including sparks, flames, and hot surfaces. Use only explosion-proof electrical equipment and ground all containers during transfer operations. Never smoke or use open flames in areas where the substance is handled or stored.

2-methylpropane must be stored in approved pressure vessels in cool, well-ventilated areas away from heat sources, ignition sources, and direct sunlight. Storage areas should be equipped with appropriate fire detection and suppression systems. Keep containers upright and secured to prevent falling. Store separately from oxidizing agents, acids, and other incompatible materials. Regular inspection of storage containers for leaks and damage is essential for safe storage.

2-methylpropane exposure requires immediate action depending on the route of contact. For inhalation, move the person to fresh air immediately and seek medical attention if breathing difficulties occur. In case of skin contact from liquid form, remove contaminated clothing and flush affected area with water. For eye contact, rinse thoroughly with water for at least 15 minutes and seek medical advice. Never attempt rescue in confined spaces without proper breathing apparatus.

2-methylpropane disposal must comply with local and national waste regulations as it is classified as hazardous waste. Empty containers should be returned to suppliers or specialized waste management companies. Never release the gas directly into the atmosphere or dispose of it in regular waste streams. Contact licensed waste disposal contractors who can handle pressurized gas containers safely through controlled venting or recovery systems in accordance with environmental protection standards.

2-methylpropane is classified under ADR Class 2 as a flammable gas, requiring specialized transportation procedures. It must be transported in UN-approved pressure vessels with appropriate labeling including flammable gas hazard labels. Vehicles must be equipped with proper ventilation, fire extinguishers, and emergency response equipment. Transport personnel require hazardous materials training certification, and specific routing restrictions may apply to avoid populated areas and tunnels.

2-methylpropane is subject to comprehensive chemical regulations including REACH registration requirements in Europe and CLP classification as a flammable gas. It falls under pressure equipment directives for storage and handling systems. The substance is not listed as an SVHC under REACH but must comply with workplace exposure limits and environmental emission standards. Users must maintain safety data sheets and implement appropriate risk management measures according to regulatory requirements.
