Allgemeine Beschreibung
4-Ethylguaiacol is a volatile compound, belonging to the class of phenols. It is identified as one of the key aroma components in commercial soy sauce, red wine, and apple cider. The unpleasant smoky, spicy, and clove-like aroma in wine is due to the presence of high concentrations of 4-Ethylguaiacol.
Synthese
4-Ethyl-2-methoxyphenol is produced from ortho-Dichloro ethylphenol by heating with Ethyl benzyl disulfonic acid and aqueous alkali at 180-200℃, followed by single Methylation.
