Chemische Eigenschaften

Guaiacol appears as white or slightly yellow crystals or colorless to light yellow transparent oily liquid. It has a distinctive scent. It is slightly soluble in water and benzene, also easily soluble in glycerol. And it is miscible with ethanol, ether, chloroform, oil and glacier acetic acid. Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. It is also present in wood smoke, as a product of pyrolysis of lignin.

Occurrence

Detected in the distillation product from guaiac resin; guaiacol is found in castoreum oil, in the essential oil from fowers of Pandanus odoratissimus L , in the distillation waters of orange leaves, in the essential oil of Ruta Montana L and in the essential oil of tobacco leaves Also reported found in lemon peel oil, bog blueberry, asparagus, cabbage, celery, onion, chive, tomato, peppermint oil, rye bread, Parmesan cheese, butter, smoked fsh, meats, barley, dried bonito, malt, hardwood smoke, cognac, beer, brandy, rum, whiskies, sherry, grape wines, cocoa, coffee, tea, peanuts, popcorn, soybeans, avocado, beans, mushroom, sesame seed, mango, tamarind, rice dill, licorice, corn oil, cuttlefsh and other sources

Verwenden

Guaiacol is a precursor of vanillin and santalidol (a synthetic sandal- wood fragrance). it is obtained from wood tar by the destructive distillation of hardwood, by the distillation of the phenol fraction of coal tar, or through the use of o-dichlorobenzene. it is processed to yield vanillin.

Definition

ChEBI: Guaiacol is a monomethoxybenzene that consists of phenol with a methoxy substituent at the ortho position. It has a role as an expectorant, a disinfectant, a plant metabolite and an EC 1.1.1.25 (shikimate dehydrogenase) inhibitor. It is functionally related to a catechol.

synthetische

Guaiacol can be obtained by diazotization and hydrolysis of anthranium anisole or obtained from fractionated of wood oil.
In the nature of guaiacol is presented in the guaiacum or pine oil. In the creosote oil obtained from wood dry distillation, guaiacol is the major ingredient. This product could be obtained through fractional distillation of creosote oil. Japan Osaka Refining Company takes o-nitrochlorobenzene as raw material, first synthesizes o-nitroanisole, and then reduces it to o-anisidine, and finally obtains the goods. China's production method is roughly the same. Ingredient consumption quota: 1250 kg / t of amino-containing anisole, 1500 kg / t of sulfuric acid (93%), 700 kg / t of sodium nitrite and 400 kg / t of copper sulfate.

Allgemeine Beschreibung

Guaiacol is a colorless to amber crystals or liquid. Density (of solid) 1.129 g / cm3. Solidifies at 28°C (82.4°F), but may remain liquid for a long time even at a much lower temperature. Slightly water soluble . Soluble in aqueous sodium hydroxide. It is an agent thought to have disinfectant properties and used as an expectorant.

Air & Water Reaktionen

Sensitive to air and light (darkens). Slightly water soluble.

Reaktivit?t anzeigen

Guaiacol may react with oxidizing materials. Guaiacol forms salts readily with bases.

Hazard

Toxic by ingestion and skin absorption.

Brandgefahr

Guaiacol is combustible.

l?uterung methode

Crystallise guaiacol from *benzene/pet ether or distil it in a vacuum. [Beilstein 6 H 768, 6 IV 5563.]

Toxicity evaluation

LD50:900 mg / kg (rat, subcutaneous).
LD50: 3.7 mg / kg (rabbit, intravenously).
Oral administration of large amount can stimulate the esophagus and stomach, resulting in heart failure, collapse and death.
