Propyl butyrate Usage And Synthesis
Chemical PropertiesClear colorless liquid
Chemical PropertiesPropyl butyrate has a pineapple and apricot-like odor with a sweet, fruity flavor of banana and pineapple. The odor is also described as sharp, pungent, rancid, sweaty and sickening.
OccurrenceReported found in fresh apple, cooked apple, apricot, banana, lemon papaya, Camembert cheese, Gruyere de Comte cheese, provolone cheese, purple passion fruit juice, apple juice, rum, fresh plums, jack fruit, ceriman or pinanona (Monstera deliciosa Liebm.), papaya, spineless monkey orange, starfruit, kiwifruit, wood apple and cherimoya.
UsesSolvent mixture for cellulose ethers.
DefinitionChEBI: Propyl butyrate is a butyrate ester resulting from the formal condensation of the hydroxy group of propanol with the carboxy group of butyric acid. It has a role as a human metabolite, a plant metabolite and an insect attractant. It is functionally related to a propan-1-ol.
PreparationFrom propyl alcohol and butyric acid in the presence of p-toluenesulfonic acid in benzene solution at the boil.
Aroma threshold valuesDetection: 0.8 to 124 ppb
Taste threshold valuesTaste characteristics at 20 ppm: sweet, fruity, tutti-frutti, bubble gum and pineapple-like, with a slight green nuance.
Synthesis Reference(s)The Journal of Organic Chemistry, 58, p. 6421, 1993 DOI: 10.1021/jo00075a043
General DescriptionNatural Occurrence: Apple, banana, kiwi, melon, papaya, passion fruit, rum and strawberry.
HazardIrritant to mucous membranes, narcotic in high concentration.
