Pent-2-ene

Pent-2-ene is an alkene hydrocarbon with the molecular formula C5H10 and CAS number 109-68-2. It is an unsaturated organic compound featuring a double bond between the second and third carbon atoms in a five-carbon chain. With a molecular weight of 70.13 g/mol, pent-2-ene exists as geometric isomers (cis and trans forms) and is classified as a highly hazardous substance with carcinogenic and mutagenic properties.

Pent-2-ene is a colorless liquid at room temperature with a characteristic hydrocarbon odor. As an alkene, it is highly flammable and has low water solubility but is miscible with most organic solvents. The compound has a relatively low boiling point typical of light hydrocarbons and exhibits the chemical reactivity characteristic of alkenes, including addition reactions across the double bond.

Pent-2-ene is primarily used as a chemical intermediate in organic synthesis and petrochemical processes. It serves as a building block for manufacturing various chemicals, polymers, and specialty compounds. The substance is also utilized in research applications and as a starting material for producing other alkenes or saturated hydrocarbons through various chemical transformations including hydrogenation, halogenation, and polymerization reactions.

Pent-2-ene requires extreme caution due to its carcinogenic and mutagenic properties (Carc. 1B; Muta. 1B). Use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work in well-ventilated areas or under fume hoods to prevent inhalation. Avoid skin contact and ensure proper grounding to prevent static electricity buildup. Emergency shower and eyewash stations should be readily accessible.

Pent-2-ene must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its flammability (ADR Class 3). Use appropriate containers designed for flammable liquids and ensure proper grounding. Store separately from oxidizing agents and incompatible materials. Maintain storage temperature below the substance's flash point and implement appropriate fire suppression systems in storage areas.

In case of skin contact with pent-2-ene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush with clean water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Seek immediate medical attention in all cases due to the substance's carcinogenic and mutagenic properties. Do not induce vomiting if ingested.

Pent-2-ene disposal must comply with local and European waste regulations due to its hazardous classification. The substance should be treated as hazardous waste and disposed of through licensed waste management facilities capable of handling carcinogenic materials. Never discharge into sewers, waterways, or soil. Incineration at appropriate high-temperature facilities with proper emission controls is typically the recommended disposal method for this type of organic compound.

Pent-2-ene is classified as ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport protocols. Use UN-approved packaging suitable for flammable liquids and ensure proper labeling with GHS08 pictogram and 'Danger' signal word. Transport vehicles must comply with ADR regulations for flammable substances, including appropriate placarding, equipment, and driver certification. Avoid transport during extreme weather conditions and ensure emergency response information accompanies shipments.

Pent-2-ene is subject to comprehensive European regulations including REACH registration requirements and CLP classification as Carc. 1B and Muta. 1B. The substance requires special authorization procedures due to its carcinogenic and mutagenic properties. Workplace exposure limits apply, and employers must implement strict control measures. Import/export may require additional permits, and use is restricted to industrial applications with appropriate risk management measures in place.
