Vanilin
Vanillin is an organic compound with the molecular formula . It is a phenolic aldehyde. Its functional groups include aldehyde, hydroxyl, and ether. It is the primary component of the ethanolic extract of the vanilla bean. Synthetic vanillin is now used more often than natural vanilla extract as a flavoring in foods, beverages, and pharmaceuticals. Vanillin and ethylvanillin are used by the food industry; ethylvanillin is more expensive, but has a stronger Note (perfumery), note. It differs from vanillin by having an ethoxy group (−O−CH2CH3) instead of a methoxy group (−O−CH3). Natural vanilla extract is a mixture of several hundred different compounds in addition to vanillin. Artificial vanilla flavoring is often a solution of pure vanillin, usually of synthetic origin. Because of the scarcity and expense of natural vanilla extract, synthetic preparation of its predominant component has long been of interest. The first commercial synthesis of vanillin began with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethylvanillin
Ethylvanillin is the organic compound with the chemical formula, formula (C2H5O)(HO)C6H3CHO. This colorless solid consists of a benzene ring with hydroxyl, ethoxy, and aldehyde, formyl groups on the 4, 3, and 1 positions, respectively. It is a Homologous series, homologue of vanillin, differing on the 3 position. Preparation Ethylvanillin is prepared from catechol, beginning with ethylation to give guaethol (1). This ether condenses with glyoxylic acid to give the corresponding mandelic acid derivative (2), which by oxidation (3) and decarboxylation, gives ethylvanillin (4).Karl-Georg Fahlbusch, Franz-Josef Hammerschmidt, Johannes Panten, Wilhelm Pickenhagen, Dietmar Schatkowski, Kurt Bauer, Dorothea Garbe, Horst Surburg "Flavors and Fragrances" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim: 2002.
