Propan-2-ol

Propan-2-ol is a secondary alcohol with the molecular formula C3H8O and CAS number 67-63-0. Also known as isopropyl alcohol or IPA, it has a molecular weight of 60.1 g/mol. This chemical compound is classified as a flammable liquid with irritant properties, requiring careful handling due to its fire hazard and potential to cause eye irritation and specific target organ toxicity.

Propan-2-ol is a colorless, volatile liquid with a characteristic sharp, alcoholic odor. It has excellent solubility in water and most organic solvents due to its polar hydroxyl group. The compound has a boiling point of 82.6°C and a flash point of 11.7°C, making it highly flammable. Its density is lower than water at approximately 0.785 g/cm³ at room temperature.

Propan-2-ol is widely used as a cleaning solvent, disinfectant, and degreasing agent in industrial applications. It serves as an intermediate in chemical synthesis, particularly in pharmaceutical and cosmetic manufacturing. Common applications include electronics cleaning, surface preparation, extraction processes, and as a component in cleaning formulations. Its antimicrobial properties make it valuable for sanitization purposes in various industries.

Propan-2-ol requires careful handling due to its flammable nature and irritant properties. Use appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and ensure adequate ventilation. Eliminate ignition sources and use explosion-proof equipment. Avoid direct skin and eye contact, and prevent inhalation of vapors. Ground containers during transfer operations and maintain fire extinguishing equipment nearby during use.

Propan-2-ol must be stored in a cool, well-ventilated area away from heat sources, sparks, and open flames. Use appropriate fire-resistant storage cabinets and ensure containers are tightly sealed to prevent vapor accumulation. Keep away from strong oxidizing agents and acids. Storage areas should be equipped with appropriate fire suppression systems and spill containment measures to prevent environmental contamination.

Propan-2-ol exposure requires immediate action depending on contact type. For skin contact, remove contaminated clothing and rinse thoroughly with water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical assistance.

Propan-2-ol disposal must comply with local and national waste regulations as a hazardous flammable liquid. Do not dispose of down drains or into the environment. Collect waste in appropriate containers labeled for flammable solvents and arrange disposal through licensed hazardous waste contractors. Small quantities may be recovered through distillation for reuse, while contaminated materials require specialized treatment facilities.

Propan-2-ol is classified under ADR as Class 3 (flammable liquids), Packing Group II, indicating moderate danger during transport. Packages must bear appropriate hazard labels and documentation. Use UN-approved packaging designed for flammable liquids and ensure vehicles are equipped with appropriate fire extinguishing equipment. Drivers require ADR certification for hazardous goods transport, and specific routing restrictions may apply.

Propan-2-ol is regulated under CLP regulation with classification as Flam. Liq. 2, STOT SE 3, and Eye Irrit. 2, requiring GHS02 and GHS07 pictograms with 'Danger' signal word. It falls under REACH registration requirements but is not classified as an SVHC substance. National regulations may impose additional restrictions on storage quantities, workplace exposure limits, and emission controls.
