Butan-2-ol

Butan-2-ol is a secondary alcohol with the molecular formula C4H10O and CAS number 78-92-2. Also known as sec-butanol or methyl ethyl carbinol, it belongs to the butanol family of alcohols. With a molecular weight of 74.12 g/mol, butan-2-ol is classified as a flammable liquid and poses moderate health hazards including eye irritation and specific target organ toxicity. It is widely used as an industrial solvent and chemical intermediate in various manufacturing processes.

Butan-2-ol is a colorless liquid with a characteristic alcohol odor at room temperature. It has moderate solubility in water due to its hydroxyl group while being miscible with most organic solvents. The compound has a boiling point of approximately 99-100°C and a flash point around 24°C, contributing to its flammable liquid classification. Its density is lower than water, and it exhibits typical secondary alcohol chemical reactivity including oxidation to ketones and esterification reactions.

Butan-2-ol serves primarily as an industrial solvent for paints, coatings, and adhesives due to its excellent dissolving properties. It functions as a chemical intermediate in the synthesis of various compounds including esters, ethers, and other organic chemicals. The compound is also used in the production of flotation agents, extraction processes, and as a component in cleaning formulations. Additionally, it finds applications in the pharmaceutical and cosmetic industries as a processing aid and solvent for active ingredients.

Butan-2-ol requires careful handling with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and adequate ventilation to prevent vapor inhalation. Avoid contact with eyes, skin, and respiratory system due to its irritant properties. Keep away from ignition sources, heat, and flames as it is a flammable liquid. Work in well-ventilated areas or use local exhaust ventilation to control vapor exposure. Ensure grounding and bonding when transferring to prevent static electricity buildup.

Butan-2-ol must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Use appropriate containers compatible with alcohols and ensure they are tightly sealed to prevent vapor release. Store separately from strong oxidizing agents, acids, and incompatible materials. Maintain storage temperatures below 25°C when possible and ensure adequate fire suppression systems are available. Keep containers upright and clearly labeled according to GHS requirements with appropriate hazard pictograms.

Immediate action is required following butan-2-ol exposure to minimize health effects. For eye contact, flush immediately with plenty of water for at least 15 minutes and seek medical attention. In case of skin contact, wash thoroughly with soap and water, removing contaminated clothing. If inhaled, move to fresh air immediately and seek medical help if breathing difficulties occur. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician in case of significant exposure or persistent symptoms.

Butan-2-ol disposal must comply with local and national hazardous waste regulations as it is classified as flammable waste. Contact licensed waste disposal companies specialized in handling flammable organic solvents for proper treatment. Do not pour down drains, sewers, or onto the ground as it can contaminate water sources. Small quantities may be incinerated in approved facilities with adequate emission controls. Always consult local environmental authorities for specific disposal requirements and maintain proper waste documentation for regulatory compliance.

Butan-2-ol is classified under ADR Class 3 (Flammable Liquids), Packing Group II, requiring specific transport regulations compliance. Use appropriate UN-specification packaging designed for flammable liquids with proper labeling including hazard diamonds and identification numbers. Vehicles must carry appropriate placards and emergency equipment according to ADR requirements. Drivers need specialized training for dangerous goods transport. Ensure proper documentation including transport documents and emergency response information accompanies all shipments. Avoid transport during extreme weather conditions that could increase fire risk.

Butan-2-ol is regulated under multiple European frameworks including REACH registration requirements for manufacturers and importers above tonnage thresholds. The CLP Regulation mandates proper classification and labeling with Warning signal word and GHS02/GHS07 pictograms. It is not currently listed as a Substance of Very High Concern (SVHC) under REACH. Workplace exposure limits may apply under occupational health regulations. Users must comply with local environmental discharge limits and waste disposal regulations. Industrial users should maintain safety data sheets and conduct appropriate risk assessments.
