2,6-Dimethylphenol Usage And Synthesis

Chemical Properties

colourless crystals or white powder

Occurrence

Reported found in smoked fatty fish, boiled and cooked cured pork, rum, malt whiskey, Japanese whiskey, coffee, katsuobushi (dried bonito) and lamb’s lettuce (Valerianella locusta).

Uses

CAS # : 576-26-1

Uses

Intermediate for Plastics, Agrochemicals, Pharmaceuticals, and is used as a solvent.

Uses

Similar to other xylenol compounds, 2,6-dimethylphenol is used in the synthesis of anti-oxidant compounds due to the phenol moiety in the structure. In addition, this compound is used as a a reactant in the synthesis of polyphenylene ether polymers.

Preparation

From coal tar oil or coal hydrogenation.

Aroma threshold values

Detection: 400 ppb

General Description

Colorless to off-white crystalline solid with a sweet tarry odor. Odor threshold concentration: 0.4 mg/L .

Air & Water Reactions

Insoluble in water

Reactivity Profile

2,6-Dimethylphenol is incompatible with bases, acid chlorides, acid anhydrides, and oxidizing agents. Corrodes steel, brass, copper, and copper alloys.

Fire Hazard

2,6-Dimethylphenol is combustible.

Purification Methods

Fractionally distil 2,6-xylenol under nitrogen, crystallise it from *benzene or hexane, and sublime it at 38o/10mm. [Beilstein 6 IV 3122.]
