Benzoin Chemical Properties,Uses,Production

Chemical Properties

light yellow powder or crystals with a camphor-like odour

Chemical Properties

Benzoin has a faint, sweet, balsamic odor.

Uses

Degassing for powder coatings

Uses

benzoin is a fragrant essential oil with bactericidal, anti-irritation, and anti-itching properties. It is considered a good ingredient for reducing skin redness and is a preservative of fats. Although its primary constituent is benzoic acid, it also contains canillin and an oily aromatic liquid. This balsamic resin is extracted by cutting deeply into the trunks of trees that grow primarily in Indonesia and Thailand.

Definition

ChEBI: A ketone that consists of acetophenone bearing hydroxy and phenyl substituents at the alpha-position. The parent of the class of benzoins.

Definition

benzoin: A colourless crystallinecompound, C6H5CHOHCOC6H5; m.p.137°C. It is a condensation product ofbenzenecarbaldehyde (benzaldehyde),made by the action of sodiumcyanide on benzenecarbaldehyde inalcoholic solution. It also occurs naturallyas the resin of a tropical tree. Itis both a secondary alcohol and a ketone,and gives reactions characteristicof both types of compound.

Taste threshold values

Taste characteristics at 25 ppm: spicy, balsamic, resinous, fruity with an herbal nuance.

General Description

Off-white to yellow-white crystalline solid with an odor of camphor. Slightly acrid taste. When broken the fresh surfaces have a milky-white color.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-Hydroxy-2-phenylacetophenone is sensitive to heat and light. 2-Hydroxy-2-phenylacetophenone is incompatible with oxidizers. 2-Hydroxy-2-phenylacetophenone reduces Fehling's solution.

Hazard

Highly toxic.

Fire Hazard

Flash point data for 2-Hydroxy-2-phenylacetophenone are not available; however, 2-Hydroxy-2-phenylacetophenone is probably combustible.

Chemical Synthesis

It may be prepared by condensation of benzaldehyde with an alkali cyanide and used in organic synthesis.

Purification Methods

Crystallise benzoin from CCl4, hot EtOH (8mL/g), or 50% acetic acid. Also crystallise it from high purity *benzene, then twice from high purity MeOH, to remove fluorescent impurities [Elliott & Radley Anal Chem 33 1623 1961]. It can be sublimed. [Beilstein 8 IV 1279.]
