Benzyl formate is a chemical compound from the group of carboxylic acid esters .

Occurrence

Potato rose ( Rosa rugosa ), wild form

Benzyl formate occurs naturally in various plants and mushrooms (for example potato rose , coffee, vanilla).

Extraction and presentation

Benzyl formate can be obtained by reacting the mixed carboxylic acid anhydride of formic acid and acetic acid with benzyl alcohol .

properties

Benzyl formate is a slightly volatile and colorless liquid that is only sparingly soluble in water. The miscibility with water is limited. As the temperature rises, the solubility of benzyl formate in water falls to about 40 ° C. and then rises again or the solubility of water in benzyl formate rises.
