PROPYL BENZOATE Usage And Synthesis

Description

Propyl benzoate is an organic chemical compound used as a food additive. It is an ester.

Chemical Properties

Propyl benzoate has a balsamic odor reminiscent of nuts with a sweet, fruity, nut-like taste.

Chemical Properties

CLEAR COLORLESS LIQUID

Occurrence

Reported found in sweet cherry, clove stem and butter.

Uses

Propyl benzoate was used to extract desipramine, a model compound used in the electrochemical analysis by a combined hollow fiber-based liquid three-phase microextraction and voltammetric method.

Uses

Propyl benzoate has a nutty odor and sweet fruity or nut-like taste, and as such, it is used as a synthetic flavoring agent in foods. It also has antimicrobial properties and is used as a preservative in cosmetics. It occurs naturally in the sweet cherry and in clove stems, as well as in butter.

Preparation

By exchange between methyl benzoate and propyl alcohol in the presence of potassium propylate; by heating benzamide sulfate with propyl alcohol at 90 to 95°C.

Definition

ChEBI: Propyl benzoate is a benzoate ester obtained by condensation of benzoic acid and propanol. It has a balsamic odor reminescent of nuts with a sweet, fruity, nut-like taste. It has a role as a flavouring agent, a plant metabolite and an antimicrobial food preservative.

Application

Propyl benzoate is used in flavor compositions, again partly for its nut-like effect in Hazelnut and Walnut imitation, also as a powerful undertone in fruit complexes, sometimes in wine-gum flavors, imitation Blackcurrant, etc. The concentration used is equivalent to about 10 to 50 ppm in the functional product.

Reactions

Propyl benzoate can be synthesized by the transesterification of methyl benzoate with propanol.

General Description

The adsorption data of propyl benzoate was obtained by frontal analysis on a symmetry-C18 column by a mixture of methanol and water as the mobile phase.
