Pentan-2-yl acetate

Pentan-2-yl acetate is an organic chemical compound with the molecular formula C7H14O2 and CAS number 626-38-0. It belongs to the ester family, formed by the reaction between acetic acid and pentan-2-ol. With a molecular weight of 130.18 g/mol, this colorless liquid exhibits typical ester characteristics and is classified as a flammable liquid under safety regulations.

Pentan-2-yl acetate is a colorless liquid with a pleasant, fruity odor characteristic of acetate esters. It has limited solubility in water due to its organic nature but is miscible with most organic solvents including alcohols and hydrocarbons. The compound has a density lower than water and exhibits moderate volatility at room temperature, contributing to its distinctive aroma.

Pentan-2-yl acetate is primarily used as a solvent in various industrial applications including coatings, paints, and varnishes. It serves as a flavoring agent in the food industry due to its pleasant fruity aroma, and finds applications in the fragrance industry for perfumes and cosmetics. The compound is also utilized in chemical synthesis processes as an intermediate or reaction medium.

Pentan-2-yl acetate requires careful handling due to its flammable nature (Flam. Liq. 3 classification). Use appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation and avoid ignition sources. Work in well-ventilated areas away from heat, sparks, and open flames to minimize fire risk.

Pentan-2-yl acetate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources. Keep containers away from incompatible materials such as strong oxidizing agents and acids. Storage areas should be equipped with appropriate fire suppression systems and maintained at temperatures below 25°C to prevent vapor buildup and degradation.

In case of skin contact with pentan-2-yl acetate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water. For eye contact, rinse immediately with plenty of clean water for at least 15 minutes. If inhaled, move the person to fresh air immediately. Seek medical attention if irritation persists or if large quantities have been ingested.

Pentan-2-yl acetate must be disposed of according to local and national hazardous waste regulations. Do not pour down drains or dispose of with regular waste due to its flammable nature. Contact licensed waste disposal companies for proper collection and treatment. Small quantities can often be recovered through solvent recovery processes, while larger volumes require specialized incineration in approved facilities.

Pentan-2-yl acetate is classified under ADR Class 3 (flammable liquids), Packing Group III for transport purposes. It must be packaged in UN-approved containers with appropriate hazard labels including the GHS02 flame pictogram. Transport vehicles must comply with ADR regulations for Class 3 substances, including proper placarding, driver certification, and emergency equipment requirements.

Pentan-2-yl acetate is subject to standard chemical regulations including REACH registration requirements in Europe and CLP classification as Flam. Liq. 3 with Warning signal word. It is not classified as a Substance of Very High Concern (SVHC). Users must comply with occupational health and safety regulations, proper labeling requirements, and maintain safety data sheets for workplace use.
