Benzyl acetate is a chemical compound from the group of carboxylic acid esters .
Occurrence
Benzyl acetate occurs naturally in many fruits, mushrooms and especially flowers and their oils (for example jasmine oil and ylang-ylang oil ).
Extraction and presentation
Benzyl acetate can be obtained by reacting benzyl alcohol with acetic acid and sodium acetate or benzyl chloride with alkali acetates .
use
Because of its flowery smell, benzyl acetate is mainly used as a fragrance and also as a solvent (e.g. for cellulose acetates and nitrates, oils, lacquers, polishes and inks) and is contained in printing inks, lacquers and leveling agents in coating materials.
safety instructions
The vapors of benzyl acetate can form an explosive mixture with air ( flash point 102 ° C, ignition temperature 460 ° C).
