説明
Ethyl benzoate, C
9H
10O
2, is the ester formed by the condensation of benzoic acid and ethanol. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents.
As with many volatile esters, ethyl benzoate has a pleasant odor which could be described similar to wintergreen mint. It is a component of some artificial fruit flavors.
化学的特性
Ethyl benzoate is a colourless liquid that has a somewhat fruity odor similar to ylang-ylang, but milder than methyl benzoate. Soluble in ethanol, ethyl ether, petroleum ether, propylene glycol, mineral oil and most non-volatile oils, insoluble in water and glycerin.
天然物の起源
Reported found in volatiles from hard, mature peaches, pineapple and currant. Also reported found in apple
juice, banana, guava, cranberry, raspberry, sweet cherry, Parmesan cheese, butter, milk, white wine, red wine, cider, whiskies, cocoa,
black tea, fresh plum, apple brandy, cherry brandy, Bourbon vanilla, naranjilla fruit, ceriman or pinanona, pimento berry, olive and
