| | Propyl butyrate Usage And Synthesis |
| Chemical Properties | Clear colorless liquid | | Chemical Properties | Propyl 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. | | Occurrence | Reported 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. | | Uses | Solvent mixture for cellulose ethers.
| | Preparation | From propyl alcohol and butyric acid in the presence of p-toluenesulfonic acid in benzene solution at the boil. | | Definition | ChEBI: 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. | | Aroma threshold values | Detection: 0.8 to 124 ppb | | Taste threshold values | Taste 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 Description | Natural Occurrence: Apple, banana, kiwi, melon, papaya, passion fruit, rum and strawberry. | | Hazard | Irritant to mucous membranes, narcotic in
high concentration.
