Ethyl 2-methylpentanoate(CAS#39255-32-8)

Introduction

Ethyl 2-methylvalerate, also known as isoamyl acetate, is introduced below in terms of its properties, uses, preparation methods, and safety information:Properties:Ethyl 2-methylvalerate is a colorless liquid with a distinctive aroma. It has low to moderate volatility and is soluble in common organic solvents such as alcohols and ethers.Uses:Ethyl 2-methylvalerate is primarily used as a solvent and reaction medium. In organic synthesis, it is commonly used in the production of fragrances, preservatives, dyes, coatings, and adhesives. It is also widely applied in household chemicals, pharmaceuticals, and pesticides.Preparation:Ethyl 2-methylvalerate is typically prepared through the esterification of isovaleric acid with methanol. Isovaleric acid and methanol are added to a reaction vessel, along with an acid catalyst or acidic ion-exchange resin, usually under heated conditions. The product, ethyl 2-methylvalerate, is then purified by distillation.Safety Information:Ethyl 2-methylvalerate is a flammable liquid and can ignite upon exposure to fire or high temperatures, releasing toxic gases. Appropriate protective gloves and goggles should be worn to avoid direct contact with skin and eyes. In case of accidental inhalation or skin contact, immediate washing is required. During storage, ethyl 2-methylvalerate should be kept in a sealed container, away from fire sources and oxidizing agents.
